(Summary) While prolonged sedentary behaviors (SBs) increase cardiovascular disease (CVD) risk, interrupting prolonged sitting (PS) with frequent light exercise reduces arterial functional decline. Skeletal muscle electrical stimulation (EMS) enhances peripheral circulation through passive muscle contraction, suggesting that EMS reduces CVD risk by providing an alternative to active exercise for prolonged SBs. This study aimed to investigate the effects of EMS to skeletal muscles during PS on the endothelial function of the brachial artery (BA). Study participants included 12 healthy adult men who were subjected to 15 min of supine rest, followed by 1 h of PS only (control [CON] trial), or 20 min of EMS to the lower extremities at 50% of the maximum tolerance intensity during PS (EMS trial). Flow-mediated dilation (FMD) of the BA was measured before and 30 min after PS, and normalized FMD (nFMD) was calculated. The nFMD of the CON trial significantly decreased 30 min after PS completion (6.21% ± 1.13%) compared with that before PS (7.26% ± 0.73%), and there was no significant change in the EMS trial before and after PS. The EMS trial showed a significant increase in the nFMD 30 min after PS completion (1.14 ± 0.77) compared with that before PS (0.84 ± 0.43). However, no significant difference was observed in the CON trials. Passive contraction of the lower extremity muscles by EMS increases BA nFMD, suggesting that prolonged sedentary lower extremity EMS use may reduce the risk of vascular endothelial dysfunction.

(Summary) This study aimed to determine whether arm-cranking training with electrical muscle stimulation (EMS) results in a greater improvement in vessel function than performing the same exercise without EMS. First, nine healthy young men performed two 20-min arm-cranking trials at 50% V O with and without EMS applied to the lower limbs. The flow-mediated vasodilation (FMD) of the right brachial artery was measured using a high-resolution ultrasound device. Both FMD and normalized FMD were increased significantly after the arm-cranking with EMS trial, and significant differences were observed between the two trials. Second, 16 healthy adult men were randomly assigned to either the arm-cranking exercise training (A) group or arm-cranking training with EMS (A+EMS) group. The subjects were engaged in 20 min of arm-cranking at 50% V O twice a week for 8 weeks with/without EMS applied to the lower limbs. The FMD increased significantly after A+EMS training session and the FMD in A+EMS group was significantly higher than that in the A group. These results indicate that acute/chronic endurance arm-cranking with EMS applied to the lower limbs improves the brachial artery endothelial function more markedly than the same exercise without EMS.

(Summary) <p></p><p>High-intensity interval exercise leads to greater improvements in the vascular endothelial function than continuous exercise at moderate intensity. However, few studies have been performed on the effects of repetition exercise consisting of high-intensity exercise followed by complete rest on the arterial function. Therefore, the purpose of this study was to investigate the effects of repetition exercise on the vascular endothelial function determined by flow-mediated vasodilation (FMD). Eleven healthy male subjects completed two exercise sessions on a cycle ergometer in a counterbalanced order. The exercise sessions were 20 min cycling at 50% maximal work rate (W<sub>max</sub>) (continuous exercise, CE) and 20 × 20-sec intervals at 100%W<sub>max</sub> interspersed with 40-sec intervals at complete rest (repetition exercise, RE). Before and after each protocol, the brachial systolic and diastolic blood pressure were measured in the supine position. Relative FMD was assessed at rest and 30 and 60 min after each exercise regimen, and then the normalized FMD (nFMD) was calculated from the peak shear rate. The FMD significantly increased 30 min after RE (8.2 ± 1.5% to 11.5 ± 3.1%, p<0.01) and non-significantly increased 30 min after CE (7.5 ± 1.6% to 8.1 ± 2.1%, n.s.) before returning to baseline at 60 min after both exercise regimens. The FMD value at 30 min after RE was significantly greater than that at 30 min after CE (p<0.01). The nFMD (a.u.) significantly increased 30 min after RE (1.38 ± 0.64 to 2.00 ± 0.94, p<0.05) and non-significantly increased 30 min after CE (1.20 ± 0.54 to 1.49 ± 0.57, n.s.) before returning to baseline at 60 min after both exercise regimens. These results suggest that repetition exercise may lead to an acute improvement in the vascular endothelial function.</p> (Keyword) vascular endothelial function / continuous exercise / repetition exercise (Tokushima University Institutional Repository) ● Metadata: 115222 (Link to Publication Site) ● Publication site (DOI): 10.7600/jspfsm.68.199 (Link to Search Site for Scientific Articles) ● CiNii @ National Institute of Informatics (CRID): 1390001288138658944 ● Summary page in Scopus @ Elsevier: 2-s2.0-85066310460 (Tokushima University Institutional Repository: 115222, DOI: 10.7600/jspfsm.68.199, CiNii: 1390001288138658944, Elsevier: Scopus)

(Summary) <p></p><p>Endurance exercises such as cycling and running are useful for improving the arterial function and preventing cardiovascular disease (CVD). However, subjects suffering from spinal cord injury (SCI) or lower limb osteoarthritis (OA) cannot perform these kinds of lower limb exercises. Recently, electrical muscle stimulation (EMS) has been shown to be able to increase the muscle strength and blood flow and improve the peripheral circulation. Arm-cranking exercises with EMS may therefore be able to reduce the risk of CVD for patients with SCI and lower OA. However, this point has not been fully clarified. The purpose of this study was to assess the effect of submaximal arm-cranking exercise with EMS on arterial stiffness. Ten healthy young subjects performed submaximal arm-cranking exercise alone (A) and submaximal arm-cranking exercise with EMS (A+E). In the A+E trial, the submaximal arm-cranking exercise was performed at 30%VO<sub>2</sub> max for 20 min while EMS was applied to their thigh and calf muscles during the exercise. The brachial-ankle pulse wave velocity (ba-PWV), systolic and diastolic blood pressure (SBP/DBP) and heart rate (HR) were measured before and after each exercise. Immediately after the exercise session, the HR of the subjects in the A+E trial was significantly elevated in comparison to those in the A trial. The SBP and DBP did not differ between the two trials to a statistically significant extent. In the A+E trial, the ba-PWV was significantly reduced immediately after exercise in comparison to the A trial (1082.6 ± 105.9 cm·sec<sup>-1</sup> vs. 1191.7 ± 86.7 cm·sec<sup>-1</sup>, p < 0.05). These findings suggest that arm-cranking exercise with EMS reduces arterial stiffness and might be useful for reducing the risk of CVD.</p> (Keyword) arm-cranking exercise / electrical muscle stimulation / pulse wave velocity (Tokushima University Institutional Repository) ● Metadata: 115220 (Link to Publication Site) ● Publication site (DOI): 10.7600/jspfsm.68.183 (Link to Search Site for Scientific Articles) ● CiNii @ National Institute of Informatics (CRID): 1390282763114691584 ● Summary page in Scopus @ Elsevier: 2-s2.0-85066325625 (Tokushima University Institutional Repository: 115220, DOI: 10.7600/jspfsm.68.183, CiNii: 1390282763114691584, Elsevier: Scopus)

(Summary) <p></p><p>As well as active smoking, passive smoking is associated with a high risk of developing cardiovascular disease. The antioxidant vitamin C may inhibit the unfavorable effects of passive smoking. In this study, we investigated the effects of vitamin C ingestion on changes in the flow-mediated dilatation (FMD) at the brachial artery in patients exposed to transient passive smoking. The study participants included seven healthy adult males who were examined by high-resolution ultrasonography of the brachial artery before and after 15-minute of passive smoking. FMD was used to examine the endothelial function. Randomized crossover controlled trial, measurements were performed on two different days 120-minute after the oral administration of 1000mg of ascorbic acid (VC trial) or a placebo (P trial). Although the FMD values decreased after passive smoking in both trials, the FMD values of the VC trial were higher than those of the P trial, with significant differences between the trials observed immediately and 30-minute after passive smoking. The results of this study suggested that the ingestion of vitamin C may suppress the decrease in the vascular endothelial function caused by transient passive smoking.</p> (Keyword) passive smoking / antioxidants / vitamin C / vascular endothelial function (Tokushima University Institutional Repository) ● Metadata: 115223 (Link to Publication Site) ● Publication site (DOI): 10.7600/jspfsm.68.153 (Link to Search Site for Scientific Articles) ● CiNii @ National Institute of Informatics (CRID): 1390001288126966784 ● Search Scopus @ Elsevier (DOI): 10.7600/jspfsm.68.153 (Tokushima University Institutional Repository: 115223, DOI: 10.7600/jspfsm.68.153, CiNii: 1390001288126966784)

Hajime Miura, Miduki Ishikawa and Kenichi Deguchi : Moderate-intensity arm-cranking exercise may not improve arterial function in healthy adult men, International Journal of Sports Medicine, Vol.39, No.13, 962-966, 2018. (Summary) Endurance exercises, such as cycling or running, are useful for improving arterial function. However, people suffering from partial paralysis or arthritis are unable to perform these kinds of lower-limb exercises. In the present study, we explored the acute effect of upper-arm exercise on arterial stiffness in healthy men. Fourteen healthy adult men performed two experimental trials. The order of experiments was randomized between a 30-min arm-cranking exercise at 50% V O (A-trial) and a 30-min leg-cycling exercise at 50% V O (C-trial). The brachial to ankle pulse wave velocity (baPWV), brachial systolic/diastolic blood pressure and heart rate were obtained with subjects in the supine position. The baseline hemodynamic values were not markedly different between the two trials. Compared with the baseline value, the baPWV was significantly reduced at 30 and 60 min after the C-trial. In the A-trial, however, there were no significant changes in the baPWV throughout the trial. These results indicate that acute 50% V O arm-cranking exercise induced relatively little change in the baPWV, which was the opposite of the finding observed with leg-cycling exercise. Therefore, in order to improve arterial function via aerobic upper-arm exercises, the exercise mode/intensity or other approaches should be considered.

(Summary) Chlorothalonil, a polychlorinated aromatic fungicide, is considered non-toxic to small mammals. However, chlorothalonil inactivates sulfhydryl enzymes and depletes cellular glutathione. Chlorothalonil increases intracellular Zn2+ concentration ([Zn2+]i) in mammalian cells possibly because intracellular Zn2+ is released via zinc-thiol/disulfide interchange. The effects of chlorothalonil at sublethal concentrations on the cellular content of nonprotein thiols ([NPT]i) and [Zn2+]i were examined using flow cytometry in rat thymocytes. Low concentrations (0.3 1 µM) of chlorothalonil increased, but high concentrations (3 10 µM) decreased [NPT]i. These effects of chlorothalonil were partly attenuated by an intracellular Zn2+ chelator. Chlorothalonil at 0.3 10 µM increased [Zn2+]i in a concentration-dependent manner, which was largely dependent on the release of intracellular Zn2+. Both the decrease in [NPT]i and increase in [Zn2+]i increase the vulnerability of cells to oxidative stress. Chlorothalonil at 1 10 µM potentiated the cytotoxicity of H2O2 (300 µM). It was also the case for 10 µM pentachloronitrobenzene, but not 10 µM pentachlorophenol. In conclusion, chlorothalonil at low (sublethal) micromolar concentrations is cytotoxic to mammalian cells under oxidative stress.

(Summary) <p>High-intensity interval exercise (IE) leads to greater improvements in the arterial function than continuous exercise at moderate intensity (CE). However, few studies have been performed on the effects of the repetition exercise (RE) on the vascular endothelial function. The purpose of this study was to compare the effects of CE vs. IE vs. RE during aerobic exercise on the vascular endothelial function determined by flow-mediated vasodilation (FMD). Ten healthy male subjects randomly performed 3 trials as follows: CE (20-min cycling at 50%W<sub>max</sub>), IE (10 × 1-min intervals cycling at 75%W<sub>max</sub> interspersed with 1-min intervals cycling at 25%W<sub>max</sub>), and RE (30 × 20-sec intervals cycling at 100%W<sub>max</sub> interspersed with 20-sec intervals at rest). FMD was assessed at rest and 30 and 60 min after each exercise, and then the normalized FMD (nFMD) was calculated from the peak shear rate. The nFMD (a.u.) significant increased 30 min after IE (1.2 ± 0.2 to 3.0 ± 1.0, p<0.05) and increased 30 min after CE (1.0 ± 0.2 to 1.4 ± 0.2, n.s.) and returned to baseline at 60 min after both exercises, while the nFMD decreased 30 min after RE (1.3 ± 0.2 to 1.2 ± 0.1, n.s.) and was sustained at 60 min. The nFMD value at 30 min after IE was significantly greater than that at 30 min after RE (3.0 ± 1.0 versus 1.2 ± 0.1, p<0.05).

(Summary) Cetylpyridinium chloride (CPC) is an antimicrobial agent used in many personal care products, with subsequent release into the environment. Since CPC is found at low concentrations in river and municipal wastewater, its influence on wildlife is of concern. Therefore, in this study, we used flow cytometry to examine the effects of sublethal concentrations of CPC on rat thymic lymphocytes in order to characterize the cellular actions of CPC at low concentrations in the presence and absence of H2O2-induced oxidative stress. CPC treatment increased the population of living cells with phosphatidylserine exposed on the outer surface of their plasma membranes (a marker of early stage apoptosis), elevated intracellular Zn2+ levels, and decreased the cellular content of nonprotein thiols. CPC also potentiated the cytotoxicity of H2O2. Our results suggest that, even at environmentally relevant sublethal concentrations, CPC exerts cytotoxic effects under oxidative stress conditions by increasing intracellular Zn2+ concentration and decreasing the cellular content of nonprotein thiols. These findings indicate that, under some in vitro conditions, CPC is bioactive at environmentally relevant concentrations. Therefore, CPC release from personal care products into the environment may need to be regulated to avoid its adverse effects on wildlife.

(Summary) <p>Habitual exercise is important for improving or maintaining the arterial function with age. However, the role of functional fitness on arterial stiffness in the elderly is unclear. This study was conducted to examine the relationships between functional fitness and arterial stiffness in elderly woman. Four hundred and seventy-nine elderly woman participated in the present investigation. The systolic/diastolic blood pressure and brachial to ankle pulse wave velocity were obtained in the supine position using an automatic pulse wave form analyzer. Four items of functional fitness (standing/sitting, walking, hand working, and self-care working) were assessed. The measurement variables were calculated for five chronological classifications (60~64, 65~69, 70~74, 75~79 and 80 yrs or over). The four items of functional fitness and brachial to ankle pulse wave velocity increased linearly with age. A multiple stepwise regression analysis revealed that systolic blood pressure (β= 0.366), age (β= 0.225), heart rate (β= 0.188), body mass index (β= -0.102), and standing/sitting (β= 0.098) were independent contributors to brachial to ankle pulse wave velocity, accounting for 29.6% of the variability.

(Summary) Regular physical exercise is recommended for the prevention and treatment of cardiovascular disease. However, it is unclear whether the effects of exercise training on arterial stiffness are the same in older hypertensive individuals as those observed in older healthy subjects. The aim of this study was to compare the effects of exercise training on arterial stiffness between older hypertensive and healthy females. Ninety-two females with untreated hypertension and 108 healthy females were randomly assigned to either the control group or to participate in a 12-week training program. In the training groups, the subjects engaged in 90 min of training twice a week for 12 weeks. Each training program included recreational activities, six to eight resistance exercises for circuit training and chair-based exercise for the lower extremities. The systolic/diastolic blood pressure (SBP/DBP) and brachial to ankle pulse wave velocity (baPWV) were obtained in the supine position using an automatic pulse wave form analyzer. Compared with that observed in the control group, greater reductions in the baPWV and SBP/DBP were achieved in both training groups (P < 0.05). Furthermore, a significant difference in the delta baPWV values obtained before and after training was noted between the hypertensive (-72.5 ± 8.1 cm s(-1)) and healthy females (-131.5 ± 107.3 cm s(-1)) who participated in the training program (P < 0.05). These data indicate that exercise training produces fewer improvements in arterial stiffness in older hypertensive females than in older healthy females.

(Summary) Interval training has a beneficial effect for treating the cardiovascular disease. However, it is not clarify the effects of different exercise intensity and duration on arterial function. In the present study, we evaluated the effect of acute short-term high and moderate- intensity interval exercise on pulse wave velocity. Thirteen healthy men were randomly as- signed to perform both acute interval exercise (IE; cycling for 24.6 min at 80%V 4 O2max and 50%V 4 O2max) and acute continuous moderate-intensity exercise (CME; cycling for 30 min at 50%V 4 O2max). The IE and CME protocols were designed such that the exercises resulted in the same workload during each session. The brachial systolic and diastolic blood pressure (SBP and DBP), and brachial to ankle pulse wave velocity (baPWV) were obtained in the supine position using an automatic pulse wave form analyzer at pre- and post-exercise. In IE, baPWV at post- exercise decreased significantly compared with pre-exercise value (1181.9±119.2 cm sec-1 vs. 1108.4±109.4 cm sec-1, p<0.01). In CME, however, it was not significantly different between pre- and post-exercise values (1173.5±137.1 cm sec-1 vs. 1164.8±96.0 cm sec-1, p=ns). No significant differences in SBP and DBP were found both protocols. These results suggest that acute short-term high and moderate-intensity interval exercise was more effective in reducing baPWV compared with acute continuous exercise.

(Summary) [Purpose] In order to establish a useful rehabilitation program for knee osteoarthritis (OA) patients, we tried to measure calf muscle oxygenation at various walking speeds. [Methods] The subjects were 7 older females with knee OA (OA group) and 7 older females who were not suffering from OA (non-OA group). All subjects performed treadmill walking at three different speeds for 2 minutes each with a rest period in between. The walking speeds were: 75% free gait speed (75%FGS), free gait speed (100%FGS), and 125% free gait speed (125%FGS). We measured muscle oxygenation {blood volume (BV) and oxygenated hemoglobin (oxy-Hb)} at the medial head of the gastrocnemius muscle (GM) and the tibialis anterior muscle (TA) using near-infrared spectroscopy (NIRS). The differences of BV and oxy-Hb (Δ) were calculated from the mean value ten seconds before the start of walking and the mean value ten seconds after the end of walking for each condition. [Results] In the OA group both BV and oxy- Hb of GM and TA showed no signi cant differences among the conditions. In the non-OA group, however, the oxy- Hb of TA showed signi cant differences between the 75%FGS and 125%FGS conditions. [Conclusion] The different muscle oxygen patterns of the OA and non-OA groups might be explained by differences in the calf muscle pumping action during gait.

33.	Hajime Miura : Arterial function during various acute exercises, The Journal of Physical Fitness and Sports Medicine, Vol.1, No.4, 605-610, 2012. (Summary) The decline in arterial function with aging is considered to be part of a physiological process reflecting elevated systolic blood pressure. However, the extent and rate of this decline can be manipulated by habitual exercise. In order to prevent and treat cardiovascular diseases (CVD), various types of exercise are recommended. The purpose of this review is to introduce the current findings on the characteristic features of arterial function during acute exercise. Moderate intensity endurance exercise increases the arterial compliance, which has beneficial effects on arterial function. In contrast to endurance exercise, acute middle-high intensity resistance exercise, or acute eccentric exercise, has unfavorable effects on arterial function. Even in endurance exercise, however, a severe intensity of endurance exercise, such as ultra-marathon races decreases arterial compliance and moderate-intensity-arm-cranking increases arterial stiffness. These findings indicate that, in order to establish an optimal exercise prescription for keeping or improving arterial function, various factors, including the exercise mode, exercise intensity or exercise volume should be taken into consideration.

(Summary) The decline in arterial function with aging is considered to be part of a physiological process reflecting elevated blood pressure. However, the extent and rate of this decline can be manipulated. Various types of exercise programs are recommended for improving and/or maintaining the arterial function in middle-aged to older individuals. To establish an optimal exercise prescription or guideline, it is necessary to determine the exercise mode, intensity, and frequency that provide the best outcomes. The purpose of this review is to introduce the potential of exercise for improving arterial function, and to review the exercise programs that can be used to reduce the risk of cardiovascular diseases. Regular endurance training has beneficial effects in arterial function in middle-age and older people. In contrast to endurance training, high-intensity resistance training decreases arterial compliance, which indicates reduced arterial function. In the case of low-intensity resistance training, eccentric resistance training, or combined endurance and resistance training, arterial function is unchanged or improved after a few of months training. To establish an optimal exercise prescription, it is also necessary to determine the training frequency. A recent study indicated that two days per week of training resulted in a decrease in the pulse wave velocity. These findings indicate that, in order to improve and/or maintain arterial function during the aging process, endurance exercise, relative low-intensity resistance training, or a combination of both types of training at least two days per week for several weeks, should be recommended for middle-aged and older individuals.

(Summary) Habitual exercise is important for improving or maintaining arterial function with age. However, the role of physical activity on arterial stiffness in adolescents is unclear. This study evaluated the influence of physical activity on the brachial-ankle pulse wave velocity (baPWV) in high school students. The baPWV, brachial systolic blood pressure (SBP), diastolic blood pressure (DBP), and body composition were assessed in 221 healthy male high school students (16.4 ± 1.5 yrs). Self-reported physical activity (PA) was evaluated by the short form of the International Physical Activity Questionnaire (IPAQ-SF). Measurement variables were calculated for four age stages (15, 16, 17, and 18 yrs). The values for baPWV, SBP and DBP increased from 15 to 18 yrs. Stepwise regression analysis showed that SBP (β = 0.496), PA (β = -0.170), age (β = 0.186), and weight (β = -0.133) were independent contributors to baPWV, accounting for 36.6% of the variability. These results support the concept that physical activity lowers baPWV, which indicates an improvement in the arterial function of adolescents as well as middle-aged to elderly people.

(Summary) Orthostatic changes induce temporary loss of circulatory regulation. Feedback systems react to cardiovascular alterations to compensate for the instability. To clarify the existence of anticipatory cardiovascular regulation during active standing, we continuously recorded blood flow velocity (BFV) in the common carotid artery and cerebral blood volume (CBV) in healthy men. The maximum BFV value decreased significantly before standing in the reaction-time condition. The decrease significantly correlated with the change in systolic blood pressure that accompanies upright standing from a supine position. The anticipatory BFV decrease disappeared during self-paced standing, and all BFV parameters significantly declined after the self-paced standing. The CBV recording showed a significant increase in oxyhemoglobin levels before standing in the reaction-time condition. Our study suggests that some feed-forward cardiovascular regulation triggered by central command could be activated before standing, and it may play a functional role in the maintenance of cerebral perfusion during standing.

(Summary) The purpose of this study was to evaluate arterial function by near infrared spectroscopy (NIRS). 16 elderly subjects were studied: 8 were arteriosclerosis obliterans patients (ASO), and 8 were healthy elderly (non-ASO). A cuff around the thigh was inflated to a pressure of 20% above their ankle systolic blood pressure for 3 min. The NIRS probe was positioned over the gatrocnemius muscle to measure oxygenated hemoglobin (O(2)Hb), and the recovery time and rate for DeltaO(2)Hb after occlusion were calculated. Compared with the non-ASO group, the ASO group had a longer recovery time (p < 0.05) and a shallower recovery rate gradient (p < 0.01). The ankle to brachial index was correlated with recovery time (r = -0.61, p < 0.01) and recovery rate (r = 0.80, p < 0.001). These data suggest that NIRS may provide an effective non-invasive method for evaluating arterial function in patients with arteriosclerosis obliterans.

(Summary) The purpose of this study was to identify the characteristics of masseter muscle oxygen consumption and common carotid blood flow (BF) during various frequencies of chewing determined by a near infrared spectroscopy (NIRS) and an ultrasound Doppler. Nine healthy men were asked to chew a stick of gum at three different frequencies; 30times min-1 (F30), 60 times min-1 (F60), and 120 times min-1 (F120). During the trial, the NIRS probe was placed on the right masseter muscle, and the ultrasound transducer was placed on the right common carotid artery. With increasing frequency, deoxy-Hb, total-Hb and blood flow increased during chewing. Compared with F30, deoxy-Hb and BF increased significantly in both F60 and F120. In total-Hb, there were significant differences between F30 and F120, between F60 and F120. These results indicated that more oxygen was consumed by the masseter muscle and more oxygen was supplied to the brain with increasing frequency of chewing.

(Summary) The purpose of this study was to evaluate the oxygenation at the frontal area during reading, calculation and finger-tasks determined by a near infrared spectroscopy (NIRS). Ten healthy subjects performed the following trials for 1 min; reading silently, reading aloud, simple calculation, difficult calculation, easy finger-tasks, and complicated finger-tasks. The NIRS-probe was placed over the frontal area. When comparing reading silently and aloud, oxygenated Hb (oxy-Hb) and blood volume (BV) were significantly larger during reading aloud. In case of calculations, oxy-Hb and BV were significantly larger during difficult calculation. For finger tasks, the level was significantly larger during the complicated tasks. These data suggested that various tasks such as reading, calculation and finger-task might be useful in the prevention of dementia. (Keyword) oxygenation / frintal cortex / near infrared spectroscopy

(Summary) The aerobic training reduces the artery stiffness and systolic blood pressure. The anaerobic training such as resistance training, however, is associated with higher artery stiffness. We hypothesized that low-intensity circuit training might improve the large artery stiffness. The purpose of this study was to determine the effects of long-term low-intensity circuit training on artery stiffness in sedentary women. Twenty healthy women divided into two groups (training group and control group). In the training group, subjects asked to perform the resistance exercises consisted of arm curls, bench presses, lateral pull-downs, leg presses and squats 3 days per week for 2 months. They conducted 5 sets at 30% of their 10RM. Aerobic capacity (ventilatory threshold [VT]), muscle strength, resting blood pressure, and arterial stiffness index (brachial - ankle Pulse Wave Velocity [baPWV]) were evaluated before and after training period. After the low-intensity circuit training, work rate at VT was significantly increased (108.6±25.6W to 128.1±24.3W). The baPWV was significantly decreased (988.7±80.5cm sec-1 to 895.7±62.6cm sec-1). In control group, however, there were no significant differences during same duration. These results suggested that long-term low-intensity circuit training attenuates the large artery stiffness in healthy women. This kind of exercise may have great potential to lower the risks of circulatory illness in aged men.

Hajime Miura, Kevin McCully, Shoko Nioka and Britton Chance : Relationship between muscle architectural features and oxygenation status determined by near infrared device, European Journal of Applied Physiology, Vol.91, No.2-3, 273-278, 2004. (Summary) This study tested whether regional differences in oxygenation status could result from differences in muscle fiber architecture. Architectural properties, oxygen supply, and consumption in the medial head of the gastrocnemius muscle (GM) were determined in vivo in six men using B-mode ultrasound and functional near infrared (NIR) imaging devices. Fascicle length, fascicle angle, NIR-O(2) saturation (deoxygenated Hb or oxygenated Hb), and NIR-blood volume (sum of deoxygenated and oxygenated Hb) were obtained in the distal and proximal portions of the GM at rest and during contraction. Exercise consisted of 2 min of standing plantar flexion at 1 Hz with an additional load of 50% of each subject's weight. Plantar flexion produced larger decreases (Delta: difference between rest and exercise values) in NIR-O(2) saturation [mean saturation (SD) of 0.14 (0.05) vs 0.07 (0.04) optical density units] and NIR-blood volume [mean saturation (SD) of -0.23 (0.08) vs -0.13 (0.04) optical density units] in the distal compared with the proximal portion ( P<0.05 for all comparisons). It also produced larger changes (Delta) in fascicle length [mean length (SD) of -16.5 (4.7) vs -8.2 (4.2) mm] and fascicle angle (mean angle (SD) of 10.8 (1.4) degrees vs 3.9 (2.1) degrees ] in the distal compared with the proximal portion ( P<0.05 for all comparisons). There were significant correlations between DeltaNIR-O(2 )saturation and Deltafascicle length ( r=-0.84, P<0.05), and between DeltaNIR-O(2) saturation and Deltafascicle angle ( r=-0.90, P<0.05), between DeltaNIR-blood volume and Deltafascicle length ( r=0.91, P<0.05), between DeltaNIR-blood volume and Deltafascicle angle ( r=-0.85, P<0.05). In conclusion, the plantar flexion exercise produced regional differences in oxygenation status consistent with regional differences in muscle architecture.

Hajime Miura, Kevin McCully and Britton Chance : Application of multiple NIRS imaging device to the exercising muscle metabolism, Spectroscopy: An International Journal, Vol.17, No.2/3, 549-558, 2003. (Summary) Near infrared spectroscopy (NIRS) is a developing technique that measures the balance between muscle oxygen consumption and oxygen supply that is noninvasive and potentially portable. Differential absorption of light in the 600-900 nm region detects the changes in small vessel hemoglobin oxygen saturation and blood volume. Recent developments include the combining of multiple light sources and photodetectors to provide `images' of oxygen saturation and blood volume of wide regions of muscle. Using multiple NIRS imaging device, we monitored localized muscle metabolism during various exercises in the field as well as in the laboratory. In healthy subjects, the regional differences in oxygen saturation and blood volume were detected in the medial head of the gastrocnemius muscle during a standing plantar flexion exercise, consistent with differences in intramuscular pressure. Patients with peripheral arterial disease (PAD) showed slower recovery for both oxygenation and blood volume after exercise. Treatment for PAD resulted in improvements in NIRS-measured recovery times. In summary, NIRS devices have the ability to detect and monitor impaired muscle circulation. In addition, NIRS devices with multiple channels have the potential to evaluate the regional differences in oxygen status. Multiple NIRS imaging devices have the potential to play an important role in monitoring exercise prescription and clinical uses.

(Summary) The knee braces offer a useful adjunct to the treatment and rehabilitation of ligamentous knee injuries. The knee brace, however, may compresses the soft tissue of the thigh and leg. The purpose of this study was to compare the muscle oxygen status with and without knee brace. Eight healthy men performed two trials with (Brace) and without knee brace (Control). Each trial consisted of 5 intermittent submaximal ankle planter flexion exercises for 1 min with 2-min recovery. Relative levels of HbO2/MbO2 (NIR-oxygenation) and Hb/Mb (NIR-deoxygenation) were measured in the medial head of gastrocnemius muscle using near infrared spectroscopy (NIR). NIR-oxygenation decreased and NIR-deoxygenation increased during contraction, and returned to resting level during recovery. In Brace trials, it was significantly different from control trials during contraction and recovery. The rate of recovery of NIR-oxygenation was slower in Brace than control trial. Knee brace produced higher deoxygenation level and slower recovery of O2 resaturation. Light surface compression (30 to 50mmHg) influences on the blood vessels, especially vein. O2 resaturation determined by NIR is a function of O2 delivery and utilization. This study suggests that the knee brace compressed the soft tissue of the thigh, such that exercise hyperemia was reduced and venous blood pooling was increased in the gastrocnemius muscle. External compression from knee brace might be responsible for premature muscle fatigue.

(Summary) Using a near infrared (NIR) imaging device, we tested the hypothesis that regional differences in oxygen status could be detected in the gastrocnemius muscle during exercise and recovery. Six healthy subjects performed the standing plantar flexion exercises for 2 min; the frequency was one contraction per second. The NIR imaging device was placed over the medial head of the right gastrocnemius muscle and the signals from two optical sensors located, respectively, on the middle proximal and middle distal portions were used. The NIR-O2 saturation (difference between deoxygenated and oxygenated Hb signals) and NIR-blood volume (sum of the oxygenated and deoxygenated Hb signals) were calculated in optical density units. Plantar flexion resulted in more deoxygenation during exercise and more reoxygenation during recovery in the distal portion compared with the proximal portion. The changes in NIR-O2 between rest and 2 min-exercise, and between 2 min-exercise and 3 min-recovery were 0.11 and -0.23, respectively, in the distal portion, which were significantly larger than proximal values (0.05 and 0.10, p<0.05). Plantar flexion resulted in lower NIR-blood volumes during exercise and greater recovery of blood after exercise in the distal portion compared to the proximal portion. The changes in NIR-blood volume between rest and 2 min-exercise, and between 2 min-exercise and 3 min-recovery were 0.19 and 0.31, respectively, in the distal portion, which were significantly larger than proximal values (-0.07 and 0.12, p<0.05 for all comparisons). These findings indicate that the distal portion of the medial gastrocnemius had larger changes in NIR-O2 saturation and NIR-blood volume than the proximal portion. This is consistent with the distal portion having greater impairment of blood flow possibly due to the higher intramuscular pressure during exercise. In conclusion: 1) regional differences in oxygen status in the gastrocnemius muscle were detected with exercise, with the distal portion having greater NIR-O2 saturation and NIR-blood volume changes, and 2) the NIR imaging device might be a useful method to detect the regional differences of oxygen status in the muscle.

(Summary) The purpose of this study was to determine the usefulness of functional near infrared (fNIR) imaging machine as a tool to identify the peripheral vascular disease. This machine is able to measure regional differences in blood volume (sum of oxygenated and deoxygenated hemoglobin) and oxygen saturation over 4x10 cm area of muscle. Six patients with peripheral vascular disease (PVD group) and six elderly subjects without any disease (Healthy group) were participated as subjects. They performed the one-legged standing plantar flexion exercise for 1 min; the frequency was one contraction per 5 sec. The probe was placed over the medial head of gastrocnemius muscle. The PVD group had a larger decrease in blood volume and oxygen saturation during 1-min exercise compared with Healthy group. After exercise, the recovery time (T1/2) of blood volume and oxygen saturation was slower in the PVD compared to the Healthy group. T1/2 in two of PVD subjects improved after taking the medication. In conclusion: 1) PVD patients showed changes in oxygen status consistent with their disease, 2) T1/2 demonstrated sensitivity to change during treatment of PVD patients, and 3) this fNIR imaging machine can be a valuable tool for the clinical assessment of PVD.

(Summary) The repeated heel-raiseis a typical stretch-shortening cyc1e (SSC) exercise. The exercise is not only performed in resistance training but also used for evaluating muscular strength in c1inical settings. The present study was undertaken to investigate the effect of repeated heel-raise exercise to a volitional exhaustion on contractile properties of the triceps surae muscle and parameters reflecting muscle injury.Five Healthy university students with no orthopedic disorders served as subjects. Each subject performed two exercises. ln SSC condition，the subjects repeated the SSC exercise every 2 seconds to volitional exhaustion. ln the IS0 condition，they repeated the same number of an isometric exercise as that of the SSC exercise.In the SSC condition，the subjects exhausted after repeating the exercise 28.6 times. At exhaustion，maximal torque developing capacity decreased significantly and the decrease was accompanied by a tendency of a lower median power frequency of the EMG signals. A significantly higher lactate concenlration was also observed. On the other hand，the ISO exercise induced no significant changes in these parameters.In the SSC condition，the decreased maximal torque developing capacity at exhaustion remained one hour and even one day following the exhausting exercise. The circumference of the lower extremity became larger significantly at exhaustion as compared with the pre-exercise values and remained higher one hour and one day after the exercise. The pressure threshold for pain in the medial head of the gastrocnemius muscle and the muscle-tendon junction of the triceps surae muscle became significantlylower compared with pre-exercise value one hour or one day following the exercise. Muscle painevaluated using visual analog scale f1uctuated and the higher value was observed at exhaustion and one day after SSC exercise. ln the ISO condition，no significant changes in these parameters were observed.The results of the present study indicated that the SSC exercise had more profound effects oncontractile properties， myo-electrical signals and injury-related parameters than the ISO exercise.Furthermore, the results suggest that，even in a relatively small number of repetitions，repeated heel-raise, at ypical SSC exercise，induces as light muscle injury.

(Summary) A walking and/or running for raising quality of life (QOL) was studied from the face of exercise physiology，exercise biochemistry，sport sociology. Three experiments and a survey were carried out to achieve the purpose. The results were summarized as follows:1) The running program in the long time was effective in the decrease of body fat percentage， the decrease of body weight as overweight person， and also in the increase of muscular endurance.2) Appropriate BMI and muscular endurance are important for the marathon race.3) Accelerometer steps per day did not significantly for correlate to body composition，health-related parameters in blood or serum adipocytokine levels.4) Each subject ofthe walk exercise must be examined from the coordination ability.5) A exercise class rises the Self-efficacy(SE)，and the individual group activity iseffective to maintain the SE.

37.	Hajime Miura : Near infrared optical imaging of human breast tissue, 2 nd International Conference on Biomedical Spectroscopy, Lomdon, Jul. 2003. (Summary) Though it has already been applied to the brain or muscle metabolism, near infrared (NIR) diffuse optical imaging has a potential to replace existing technology for measuring the human breast tissue. Recently, we developed the NIR imaging device which consisted of one LED module and four detector modules. The probe is triangular with the LED module (760 and 850nm) at one corner. These are four detector modules arranged in two lines. Each line consists of two detector modules and two lines create a 30 degree angle with the light source module at the vertex. This probe was placed over the breast tissue at eight different orientations in order to measure the oxygenation level. In order to identify the level of oxygenation before and after ovulation, the mammary glands of healthy women were measured. After ovulation, the level of oxygenated Hb at the underside of the breast was higher compared with before ovulation. This result indicated that this device could detect the severity of the hardened mammary. The final goal of this study is to apply the NIR imaging device to detect or diagnose breast cancer. The optical data showed that the control subjects exhibited homogeneous levels of oxygenation around the breast region. In the breast cancer patients, however, substantial contrasts in oxygenation levels between the tumor and adjacent parenchyma were found. These results suggest that this NIR imaging device could provide accurate and quantitative measurements of oxygenation levels of tumors without requiring knowledge of size or shape. In conclusion, NIR is a non-invasive and relatively low-cost optical technique that offers the advantage of being less restrictive than MRS, MRI or mammography and more comfortable and suitable for monitoring. Therefore, this kind of device is useful for self detection of breast cancer.

Hajime Miura, Emi Nakagawa, Kzutake Toiguchi, Kevin McCully and Britton Chance : Muscle oxygen supply and oxygenation in forearm area during sustained isometric contraction, Medicine and Science in Sports and Exercise, No.5, s40, San Francisco, May 2003. (Summary) The muscle oxygen supply is determined by many factors; vasoconstriction, driving forces, vasodilation, mechanical factors. PURPOSE: In order to identify the mechanism of peripheral circulation, we measured the blood vessel structure and muscle oxygen status in the forearm area during a high intensity of static handgrip exercise. METHODS: The artery diameter (Di) and mean blood flow velocity (MBV) in the ulnaris and radial arteries were measured by an ultrasound colored doppler imaging device. The muscle oxygenated Hb (o.d.) in the flexor carpi ulnaris and brachioradialis muscles were determined by a multiple near infrared imaging device. Seven healthy subjects performed the 1min-sustained isometric handgrip exercise without thumb at 60%MVC. RESULTS: During the trial, there is no significant difference of Di between two arteries. The MBV in the ulnaris and radial arteries was similar during muscle contraction (3.8 v.s. 3.6cm/sec, p>0.05). During recovery, the MBV in the ulnaris artery was significantly higher compared with the radial artery (14.5 v.s. 10.0cm/sec, p<0.05). The flexor carpi ulnaris muscle had a larger deoxygenation (-0.25 v.s. -0.11 o.d., p<0.05) during contraction and it has a larger re-oxygenation (0.12 v.s. 0.05 o.d., p<0.05) during recovery compared with the brachiradialis muscle. CONCLUSION: Although the ulnaris artery diameter and flow velocity did not changed during higher muscle contraction, the higher blood flow velocity and greater re-oxygenation during recovery suggested that larger circulatory compromise at ulnaris area might be occurred at the capillary beds compared with brachioradialis area.

(Summary) The multi-channel near infrared (NIR) imaging device has potential to measure physiological important differences in the regional muscle metabolism. We have developed a new NIR imaging system, which consists of one LED and 8 photodetectors. In order to identify the exercising muscle metabolism, we measured the deoxygenated Hb/Mb and total-Hb/Mb in the thigh muscles during cycling, in the calf muscles during plantar flexion exercise, and in the forearm muscles during hand grip exercise. These results suggested that regional difference of muscle oxygen status was detected in some muscle groups and even within one muscle. This multi-channel NIR imaging device is a useful tool for measuring the muscle metabolism.

42.	Hajime Miura : Application of multiple NIRS imaging device to muscle metabolism, 1 st International Conference on Biomedical Spectroscopy: From muscle to Men, Cardiff (UK), Jul. 2002. (Summary) Near infrared spectroscopy (NIRS) allows the measurement the balance between oxygen consumption and oxygen supply in relation to muscle bioenergetics in human tissue in more simple and portable way. At 760 nm, deoxygenated hemoglobin (Hb) has a higher absorbency, and at 850 nm, oxygenated Hb has a larger absorbency. The difference signal will be sensitive to changes in heme-oxygen concentration (oxygen saturation) and the sum signal to changes in overall heme concentration (blood volume). In case of measuring the muscle metabolism, some of important notices should be paid attention; 1) it is not able to evaluate the absolute value because the path length of light from light source and photodetector (PD) is not known, 2) subcutaneous fat is influenced on NIRS signal. Approach to measuring kinetics of different signal is also available. Using a NIRS, the localized muscle metabolism was detected during various exercises such as running, cycling, or rowing in the laboratory, skiing, or skating in the field. Recent interesting development with NIRS is the combining of multiple light sources and PDs. One of these imaging devices consists of the 9 light sources and 4 PDs. It allows to measure both oxygen saturation and blood volume at wide area and to show the 2-D colored imaging display. Using this device, the regional difference of muscle oxygen status during some exercises was found in the healthy subjects. In the patients with peripheral vascular disease, they have a slow recovery for both oxygenation and blood volume after exercise. After taking the medicine, their recovery time was improved. In this way, these multiple NIRS imaging device has a potential to evaluate the disease symptom. Previous multiple NIRS imaging device, however, has some problems; 1) the light sources do not cycle fast enough, indicating the lack of time resolution, 2) the distance from light source and PD is fixed. Though it has already applied to the brain metabolism or cancer detection, these multiple NIRS imaging device are also useful for measuring the muscle metabolism. The final goal with this approach is to apply the exercise prescription or rehabilitation.

Hajime Miura, Kevin McCully, Motohiko Miyachi, Shoko Nioka and Britton Chance : Heterogeneity for muscle oxygen supply and oxygenation in arm muscles during static exercise, 49th American College of Sports Medicine, Medicine & Science in Sports & Exercise, Vol.34, No.5, S166, St.Louis (USA), Jun. 2002. (Summary) During static muscle activity, mechanical compression of blood vessels increases due to the muscle tension developed. However, there is still controversy concerning oxygen supply changes. PURPOSE: In order to identify the regional difference of oxygen supply and consumption, we measured the upper-limb blood flow and oxygenation level during static handgrip exercise. METHODS: Diameter and mean blood velocity in brachial and ulnaris arteries were measured by a Doppler ultrasound device. Oxygen saturation in biceps brachial and carpi ulnaris muscles were determined by near infrared spectroscopy. Eight healthy male subjects performed the 2min-sustained isometric handgrip at 30% of maximal voluntary contraction and 2min-recovery. RESULTS: The diameter of brachial artery did not change throughout trial. In ulnaris artery, however, diameter decreased significantly during contraction and returned to resting levels after contraction (2.2 to 1.7mm). When compared to rest, mean velocity was significantly higher during contraction and faster yet during recovery. In ulnaris artery, mean velocity during recovery was significantly faster than in brachial artery (0.18 vs 0.08m/sec). Larger deoxygenation (optical density) in carpi ulnaris muscle was also found compared with biceps muscle during contraction (0.28 vs 0.12). CONCLUSION: During forearm exercise the ulnaris area produced greater changes in blood flow and oxygen consumption than the biceps brachial area. This could result from differences in mechanical compression of blood vessels in the forearm area, and is consistent with previous results in exercising calf muscles.

Hajime Miura, Daisuke Kondo, Hideki Matoba, Kevin McCully and Britton Chance : Influence of knee brace on muscle oxygen status during ankle plantar flexion, 6th IOC World Congress on Sport Science, St.Louis (USA), May 2002. (Summary) The purpose of this study was to compare the muscle oxygen status during planter flexion with and without knee brace. Eight healthy men performed two trials with (Brace) and without knee brace (Control). Each trial consisted of 5 intermittent submaximal ankle planter flexion exercises for 1 min with 3-min recovery. Relative levels of HbO2/MbO2 (NIR-oxygenation) and Hb/Mb (NIR-deoxygenation) were measured in the medial head of gastrocnemius muscle using near infrared spectroscopy (NIR). NIR-oxygenation decreased and NIR-deoxygenation increased during contraction, and returned to resting level during recovery. In Brace trials, it was significantly different from control trials during contraction and recovery. The rate of recovery of NIR-oxygenation was slower in Brace than control trial. The blood lactate concentration immediately after each trial was significantly higher in Brace compared with control. One of the most interesting findings was that muscle oxygen status determined by NIR was different between Brace and control trial. Knee brace produced higher deoxygenation level and slower recovery of O2 resaturation. Light surface compression (30 to 50mmHg) influences on the blood vessels, especially vein. O2 resaturation determined by NIR is a function of O2 delivery and utilization. This study suggests that the knee brace compressed the soft tissue of the thigh, such that exercise hyperemia was reduced and venous blood pooling was increased in the gastrocnemius muscle. Furthermore, it is suggested that reduced oxygen delivery was responsible for the higher blood lactated concentrations. From these findings, athletes and coaches should be aware of potential adverse effects of knee brace on oxygen delivery and muscle metabolism. External compression from knee brace might be responsible for premature muscle fatigue.

Hajime Miura, Kevin McCully, Motohiko Miyachi and Britton Chance : Muscle architectural features and oxygen supply during isometric contraction, 48th American College of Sports Medicine, Medicine & Sciences in Sports & Exercise, Vol.33, No.5, S263, Baltimore (USA), May 2001. (Summary) This study tested whether regional differences in oxygen supply could result from differences in muscle fiber architecture. Architectural properties, oxygen supply and consumption in medial head of gastrocnemius muscle (MG) were determined in vivo in six men using B-mode ultrasound and functional near infrared imaging (NIR) devices. Fascicle length, fascicle angle, total-Hb (sum of deoxygenated and oxygenated Hb) and deoxy/oxygenation (deoxygenated Hb or oxygenated Hb) were obtained in the distal and proximal portions in MG at rest and during contraction. The diameter of tibialis posterior artery was measured in two of subjects during contraction. Exercise protocol consisted of the 1-min isometric plantar flexion at 10.0kg load. Muscle contraction produced larger changes (delta : difference between rest and exercise values) in fascicle length (-15.7 vs. -8.5 mm) and fascicle angle (11.3 vs. 3.5 degrees) in the distal compared to proximal portion (p<0.05 for all comparisons). It also produced larger changes (delta) in total-Hb (-0.22 vs. -0.15 optical density) and deoxygenation (0.11 vs. 0.07 optical density) in the distal compared to proximal portion (p<0.05 for all comparisons). There were significant correlations between delta total-Hb and delta fascicle length (r=0.92, p<0.05), and between delta total-Hb and delta fascicle angle (r=-0.85, p<0.05), between delta deoxygenation and delta fascicle length (r=-0.80, p<0.05), between delta deoxygenation and delta fascicle angle (r=0.89, p<0.05). The reduced diameter of tibialis posterior artery was also found during contraction. Therefore, the larger changes in fascicle length and fascicle angle in the distal portion support the hypotheses that NIR measured differences in oxygen supply between distal and proximal portions are due to the architectural alterations in muscle and blood vessels.

(Summary) This study tested whether regional differences in oxygen status could result from differences in muscle fiber architecture. Architectural properties and oxygen status in medial head of gastrocnemius muscle (MG) were determined in vivo in six men using B-mode ultrasound and functional near infrared imaging (NIR) devices. Fascicle length, fascicle angle, oxygen saturation and blood volume were obtained in the distal and proximal portions in MG at rest and during exercise. Exercise consisted of plantar flexion at one contraction per second for 1 minute. Muscle contraction produced larger changes in fascicle length (-15.7 vs. -8.5 mm) and fascicle angle (11.3 vs. 3.5 degrees) in the distal compared to proximal portion (p<0.05 for all comparisons). Exercise produced larger changes in oxygen saturation (0.11 vs. 0.07) and blood volume (-0.22 vs. -0.15) in the distal compared to proximal portion (p<0.05 for all comparisons). The larger change in fascicle length and angle in the distal portion support the hypotheses that NIR measured differences in oxygen status between distal and proximal portions are due to the architectural alterations in muscle blood flow.

(Summary) 近赤外分光(NIRS)装置は非侵襲的方法のために，骨格筋，脳，肝臓などの様々な生体組織の代謝が測定可能である．近年，このNIRSの特徴を利用して，乳がんを診断する装置の開発が行われている．本研究では，近年の乳がんの罹患率の増加を踏まえ，自己検診を目指した小型NIRS装置を開発し，in vivoでの測定により評価検討した．測定プローブは7×10cmの扇型であり，光源を中心に2組の受光部(距離:1.5cm，3.0cm)が45度の角度で構成されている．第1実験として，本装置を用いて，6名の成人女性に排卵前後の乳房の上部外側の酸素動態の変化を測定した．その結果，排卵前に比べて排卵後では血液量の有意な増加が認められ，NIRSを用いて乳腺の変化を可視化することが可能であることが示された．第2実験として，乳がん患者を対象に乳頭部を中心に扇型のプローブを45度ずつ円形に移動させながら，乳房部全体の代謝を測定した．その結果，がん組織が存在する部分では他の部分と異なり，脱酸素化Hbおよび血液量の顕著な増加が認められ，本測定装置での乳がん検出の可能性が示唆された．一方，測定方法，特にプローブと乳房部の接触により生じる圧の影響で，データに大きな誤差が生じることが明らかになったため，今後，再現性の高い測定方法を見出す必要性が示された．

(Summary) 本研究では高齢者の循環器系疾患の罹患率を低下させるための運動プログラムを開発するために，高齢者を対象とした低強度抵抗性運動が動脈のスティフネスに及ぼす効果について縦断的研究を実施した．16名の高齢者(男性3名，女性13名 71.3±5.1歳)を対象にゴムチューブおよび軽量ダンベルを用いた抵抗性運動を60分間，週に2回，3ヶ月実施した．運動介入前後には，筋力，心肺能力の測定と同時に大動脈スティフネスの指標である脈派伝播速度(PWV)を測定した．その結果，左上腕部の収縮期の血圧は142.6±20.4から132.3±18.4mmHgに，脈圧は59.5±13.2から56.6±12.0mmHgに，PWVは2094.1±395.4から1874.2±264.9cm/secにそれぞれ有意に低下した．以上のことから，低強度で実施する抵抗性運動は持久的運動と同様に高齢者の大動脈のスティフネスを低下させ，収縮期血圧および脈圧の低下を促進することが示唆された．

Hajime Miura : Muscle oxygen supply and oxygenation in the forearm area during a high intensity period of static handgrip exercise, Advances in Exercise and Sports Physiology, Vol.9, No.4, 142, Aug. 2003. (Summary) The muscle oxygen supply is determined by many factors such as vasoconstriction, drving forces, vasodilation, mechanical factors. PURPOSE: In order to identify the mechanism of peripheral circulation, the blood vessel structure and muscle oxygenation in the forearm area were measured during a high intensity period of static handgrip exercise. METHODS: The artery diameter (Di) and mean blood flow velocity (MBV) in the ulnaris artery was measured by an ultrasound colored doppler imaging device. The level of muscle oxygenated Hb (oxy-Hb) in the flexor caripi ulnaris muscle was determined by a multiple near infrared imaging device. Six healthy subjects performed the1min-sustained isometric handgrip exercise without using their thumbs at 60%MVC. RESULTS: During the trial, there was no significantly difference of Di. Compared with the rest value (0.02±0.02m/sec), the MBV during contraction and recovery was significantly faster (0.07±0.04, 0.23±0.15, respectively). The flexor carpi ulnaris muiscle had a deoxygenation and it has a re-oxygenation during recovery. CONCLUSION: Although the ulnaris artery diameter did not change during high muscle contraction, the higher blood flow velocity and greater re-oxygenation suggested that larger circulatory compromise at the ulnaris area might have occurred at the capillary beds.

(Summary) 膝用スポーツ装具は膝関節の障害予防·再発予防の目的で，スポーツ，リハビリテーション等の分野で広く普及している．一方，このように膝関節周辺部に装具を装着することは，外圧(機械的締め付け)を加えることであり，筋の酸素の供給と消費のバランスに影響を及ぼす可能性が考えられる．そこで本研究では膝用スポーツ装具が足関節底屈運動時の酸素動態に及ぼす影響について明らかにしようとした．被検者は成人男性8名であり，仰臥位姿勢で等張性の足関節底屈運動を，膝用装具装着時と非装着時の2条件で実施した．なお，各条件下でのプロトコールは1分間の底屈運動を3分間の回復をはさんで5回繰り返す反復運動であった．測定の際には腓腹筋内側部に近赤外線分光装置を装着し，酸素化Hbおよび脱酸素化Hbの変化を観察した．その結果，非装着時では運動時に酸素化Hbの低下および脱酸素化Hbの増加が，また，回復時に安静レベル方向への回復がみられた．一方，装着時では運動時に酸素化Hbの低下および脱酸素化Hbの増加がみられ，脱酸素化Hbは非装着時に比べて有意に高い値を示した．また，回復時における安静レベル方向への回復の遅延がみられ，非装着時に比べて酸素化Hbは有意に低い値を，脱酸素化Hbは有意に高い値を示した．このように，膝用スポーツ装具は腓腹筋の脱酸素化レベルの上昇と回復の遅延をもたらすことが示唆された．これは装具装着による加圧が特に静脈に影響を及ぼし，静脈還流·運動性充血の抑制，静脈血の貯留などが原因と考えられる．

(Summary) Oxygen supply system at contracting muscle may be controlled by the anatomical features such as vasoconstriction or vasodilation as well as muscle functional and anatomical features. Using both near infrared spectroscopy (NIRS) and a B-mode ultrasound imaging (USI) devices, we tried to identify the characteristic features of muscle oxygen status and arterial diameter response during muscle contraction. Ten healthy subjects performed the sustained isometric handgrip of 30% maximal voluntary contraction for 1 min. The NIRS and USI devices were positioned around the flexor carpi ulnaris muscle. The total-Hb (sum of oxygenated and deoxygenated Hb signal) and the diameter of ulnaris artery were measured during trial. The total-Hb (optical density) decreased (0.0 to 0.12±0.04) during the contraction and then increased (to 0.15±0.05) over the resting level during the recovery. The vessel diameter, however, decreased (3.3±0.5 to 2.6±0.5mm) and recovered (to 3.4±0.5mm) after the contraction. These results suggest that the sustained muscle contraction produced the larger vasocontraction and decrement of total-Hb due to the larger intramuscular pressure.

(Summary) 【はじめに】トレーニングの実施，あるいは過度の運動刺激により生じた生理的な疲労は，不十分な回復により，慢性的な疲労に陥る．この際，休息·安静により急速に回復可能な症状はオーバーリーチングといわれ，また，更に長期的に不十分な回復が続く場合は，オーバートレーニング状態に陥るといわれている．これらオーバーリーチングおよびオーバートレーニングの発生機序はいまだに確立されていないが，不適切なトレーニングというストレス因子が身体および精神面に過剰なストレスを与え，生理的機能の低下を招くと考えられている．【呼吸循環応答】オーバートレーニングにともない，同一運動強度下での酸素摂取量の増大，つまり，運動効率の低下，および心拍数の増大·回復の遅延がみられている．このように全身レベルでの代謝応答については検討されているが，局所レベルについては十分に検討されていない．【活動筋の代謝応答】近年，運動生理学，リハビリテーション，臨床などの様々な分野で利用されている近赤外線分光 (NIR) 装置は組織における酸素の消費と供給のバランスを非侵襲的に測定することが可能である．NIR装置を用いて，コントロールテスト (足関節底屈運動) 時の腓腹筋の酸素化ヘモグロビン (oxy-Hb) の変化を測定したところ，以下のような結果が得られた．正常時に比べて過度のトレーニングを実施した後では，①コントロールテスト時のoxy-Hbの低下が大きくなり，酸素消費が増大すること，②運動後のoxy-Hbの回復が遅延すること，また，③数日間の休息によってテスト時のoxy-Hbの低下が小さくなり，回復の遅延が抑制される傾向が示された．このように不適切なトレーニングにより，局所筋レベルでの運動効率の低下および運動後の運動性充血 (酸素の供給) が抑制されることが示唆された．【コントロールテストの可能性】呼気ガス分析によるマクロな視点での酸素消費·心拍数の変化だけではなく，NIR装置を用いることで，より簡便にミクロな視点での筋酸素消費および供給という視点から，オーバートレーニングを推測する可能性が示唆される．

Hajime Miura, Kevin McCully and Britton Chance : Relationship between heterogeneity for oxygen status and individual differences inphysical fitness, Ono Sports Science, Vol.8, 67-76, Tokyo, Nov. 2000. (Summary) The purposes of this study were to test whether regional differences in oxygen status could result from differences in muscle fiber architecture, and to identify the oxygen status in elderly and peripheral vascular disease (PVD) subjects. Exercise consisted of one-legged plantar flexion. Architectural properties and oxygen status in medial head of gastrocnemius muscle were determined in vivo six men using B-mode ultrasound and functional near infrared imaging devices. Muscle contraction produced larger changes in oxygen saturation, blood volume, fascicle length and angle in the distal compared to proximal portion (p<0.05 for all comparisons). Change values for oxygen saturation and blood volume were correlated to the change values for fascicle length and angle between rest and exercise. In PVD, however, larger decrease in oxygen saturation and blood volume during exercise, and slower recovery following exercise was found compared with elderly subjects. The recovery time (T1/2) of oxygen saturation and blood volume was slower in PVD than elderly subjects. Sever patient had slower T1/2 and two of PVD had improved after taking of medication. In conclusion: 1) regional difference in oxygen status is due to the different muscle curvature, indicating shorter fascicle length and larger fascicle angle in distal portion, 2) PVD patients has slower recovery compared with elderly subjects, 3) T1/2 is influenced on the severity of PVD during rehabilitation period.
