The purpose of this study was to analyze the effect given to the variable details which disturb the flow of blood in brain artery disease through Aerobic exercises. It chose the subjects of study : 5 persons in an exercise group and 5 persons in a non-exercise group. Peak brain blood velocity, mean velocity, and resistance & artery stricture ratio were measured with TCD, measure machine for brain artery blood flow. The conclusion of the study was as follows: 1. At pre-test of an exercises group and a non-exercise group, PBV, MBV, BRI, ASI of a non-exercise group were showed much lower in the variation of left common carotid artery(LCCA). 2. At post-test of an aerobic exercises group and a non-exercise group, PBV, MBV, BRI, ASI of a non-exercise group were showed just a little decrease ratio but were not significant different in the variation of left common carotid artery(LCCA). Viewing on the base of these result, continuing exercises promote the functional improvement of the heart blood system and were showed the positive variation of artery stricture ratio according to brain blood flow velocity, the pulse and resistance or blood velocity. Therefore programs for prescriptions through aerobic exercises must be developed in many ways.

Purpose: The purpose of this study was to investigate the effect of blood flow restriction bridge exercise on leg muscle thickness and balance. In addition, it is to promote blood flow restriction exercise as the basis for early prevention, diagnosis, and treatment of sarcopenia in clinical practice. Methods: Twenty elderly women aged 65 years or older were selected to participate in this study. The subjects were divided into two groups of 10: one with blood flow restriction with bridge exercise (BFRG) and the other with bridge exercise alone (BG). As for the exercise method, the thickness of rectus femoris and vastus medialis and Berg balance scale were investigated by intervention for 30 minutes a day, 3 times a week, for a total of 6 weeks. Results: There was significant difference in the thickness of the rectus femoris and vastus medial and within-group changes in the Berg balance scale (p <0.05) before and after the experiment in the BFRG and BG groups (p<0.05). There was a significant difference in change between the two groups (p <0.05). Conclusion: There was a significant difference in the intragroup change of the Berg balance scale in the BFRG before and after the experiment, but there was no significant difference in the BG, and there was no significant difference in the change between the two groups.

Purpose: The purpose of this study was to identify the effects of general exercise after blood flow restriction on trunk muscles thickness in children with spastic cerebral palsy. Methods: Twenty children with cerebral palsy were assigned randomly to an experimental (n = 10) or a control (n = 10) group. The experimental group performed general exercise after blood flow restriction, while the control group performed general exercise alone. The study used an ultrasonic instrument to measure trunk muscles thickness. The Wilcoxon signed-rank test was used to determine differences before and after treatment, and the Mann-Whitney U test was used to determine differences between treatment groups. Results: From a comparison within the groups, the experimental and control groups showed significant difference in trunk muscle thickness after the experiment (p < 0.05). In a comparison between the two groups, the experimental group showed more significant difference in trunk muscle thickness than the control group (p < 0.05). Conclusion: Based on these results, general exercise after blood flow restriction effectively improves trunk muscle thickness in children with cerebral palsy.

Background: Heart attack is the most common cause of line-of-duty death in the fire service. Daily aspirin therapy is a preventative measure used to reduce the morbidity of heart attacks but may decrease the ability to dissipate heat by reducing skin blood flow. Methods: In this double-blind, placebo-controlled, crossover study, firefighters were randomized to receive 14 days of therapy (81-mg aspirin or placebo) before performing treadmill exercise in thermal-protective clothing in a hot room [$38.8{\pm}2.1^{\circ}C$, $24.9{\pm}9.1%$ relative humidity (RH)]. Three weeks without therapy was provided before crossing to the other arm. Firefighters completed a baseline skin blood-flow assessment via laser Doppler flowmetry; skin was heated to $44^{\circ}C$ to achieve maximal cutaneous vasodilation. Skin blood flow was measured before and after exercise in a hot room, and at 0 minutes, 10 minutes, 20 minutes, and 30 minutes of recovery under temperature conditions ($25.3{\pm}1.2^{\circ}C$, $40.3{\pm}13.7%\;RH$). Platelet clotting time was assessed before drug administration, and before and after exercise. Results: Fifteen firefighters completed the study. Aspirin increased clotting time before and after exercise compared with placebo (p = 0.003). There were no differences in absolute skin blood flow between groups (p = 0.35). Following exercise, cutaneous vascular conductance (CVC) was $85{\pm}42%$ of maximum in the aspirin and $76{\pm}37%$ in the placebo groups. The percentage of maximal CVC did not differ by treatment before or after recovery. Neither maximal core body temperature nor heart rate responses to exercise differed between trials. Conclusion: There were no differences in skin blood flow during uncompensable heat stress following exercise after aspirin or placebo therapy.

Background: To evaluate the effect of thoracic mobility exercise and deep breathing exercise applied to stroke patients on pulmonary function. Methods: The subjects were divided into two group. Twenty-five patients with stroke were randomly assigned to DB (deep breathing exercise) group (n=13) and TM (combination of deep breathing exercise and thoracic mobility exercise) group (n=12). During four weeks, DB group were carried out deep breathing exercises for 5~10 minutes twice a day and TM Group were carried out deep breathing exercises for 5~10 minutes and thoracic mobility exercise for 20~30 minutes twice a day. All tests were completed before and after experiment. The pulmonary functions were measured by PowerBreathe K5 (Hab International Ltd, England) and tape measure respectively. For each case, the experimental data were obtained in 4 items; average of inspiratory load, inspiratory flow speed, inspiratory flow volume and chest expansion. Results: The results of this study were as follows: 1. In DB group, the statistically significants were shown on average of inspiratory flow speed, inspiratory flow volume and chest expansion (p<.05). 2. In TM group, the statistically significants were shown on all items (p<.05). 3. There was a statistically significant difference on all items between DB group and TM group (p<.05). Conclusions: The above results revealed that DB and TM group can be used to improve pulmonary function in stroke patients. In comparison of DB and TM group, TM group was more improved. In conclude, thoracic mobility exercise helped improving function of vital capacity and chest expansion in stroke patients.

Attenuated functional exercise capacity in elderly and diseased populations is a common problem, and stems primarily from physical inactivity. Decreased function and exercise capacity can be restored by maintaining muscular strength and mass, which are key factors in an independent and healthy life. Resistance exercise has been used to prevent muscle loss and improve muscular strength and mass. However, the intensities necessary for traditional resistance training to increase muscular strength and mass may be contraindicated for some at risk populations, such as diseased populations and the elderly. Therefore, an alternative exercise modality is required. Recently, blood flow restriction (BFR) with low intensity resistance exercise (LIRE) has been used for such special populations to improve their function and exercise capacity. Although BFR+LIRE has been intensively studied for a decade, a comprehensive review detailing the effects of BFR+LIRE on both skeletal muscle and vascular function is not available. Therefore, the purpose of this review is to discuss previous studies documenting the effects of BFR+LIRE on hormonal and transcriptional factors in muscle hypertrophy and vascular function, including changes in hemodynamics, and endothelial function.

[Purpose] Eccentric exercise induces a decrease in vascular endothelial function. Curcumin, a major component of turmeric, has potent antioxidant and anti-inflammatory properties that are associated with vascular protective effects. The present study examined the effect of acute supplementation of curcumin on eccentric exercise-induced endothelial dysfunction in healthy young men. [Methods] Fourteen healthy sedentary young men (range, 21-29 years) were assigned to either the curcumin (n = 6) or placebo (n = 8) group. All subjects consumed either curcumin or placebo before exercise, and eccentric exercise of the elbow flexors was performed with their nondominant arm. Before and 60 min after exercise, brachial artery flow-mediated dilation (FMD), as an indicator of endothelial function, was measured in the non-exercised arm. [Results] Brachial artery FMD significantly decreased following eccentric exercise (p < 0.05) in the placebo group, but acute supplementation with curcumin before exercise nullified this change. The change in FMD before and after eccentric exercise between the placebo and curcumin groups was significantly different (p < 0.05). [Conclusion] The present study found that acute curcumin supplementation could attenuate the decrease in endothelial function, as measured by FMD, following eccentric exercise in healthy young men.
