The purpose of this study was to investigate the effects of glucuronic acid on antioxidative defense system and recovery of muscle fatigue in rat artier aerobic exercise. Sprague-Dawley male rats weighing 150 $\pm$ 10g were randomly assigned to one normal(N) group and three exercise training groups. Exercise training groups were classified into glucuronic acid free intubation group(T group), 250mg glucuronic acid/kg bw intubation group(TU group), and 500 mg glucuronic acid/kg bw intubation group(2TU group) according to glucuronic acid supplementation level. The glucuronic acids were administered to rats by oral intubation before exercise training. The experimental rats in exercise training groups(T, TU and 2TU) were exercised on glucuronic acid supplementation or rats in normal group were confined in cage for 4 weeks. And rats were sacrificed with an overdose of pentobarbital injection just after running. Liver xanthine oxidase(XOD) activities were not significantly different among four groups. The activity of superoxide dismutase(SOD) in T group was no significant difference from N group, but those of TU and 2TU groups were increased by 9% and 18%, respectively, compared with that of T group. Liver glutathione peroxidase(GSHpx) activites of T and TU groups showed a similar tendency to that of normal group, but increase 17% in 2TU group compared with normal group. The ratio of GSH/GSSG in liver of T group was lower than that of normal group, but those of TU and 2TU groups were a similar tendency to that of normal group. Contents of thiobarbituric acid reactive substance(TBARS) in T group was increased by 47%, compared with that of normal group but those of TU group and 2TU group were lower 27% and 35%, respectively, compared with that of T group. The contents of glycogen in soleus muscle significantly lower in all three trained exercise groups than that of normal group, but there were no significant differences among the trained exercise groups. Contents of hepatic glycogen in T group were decreased 27% compared with those of normal group while those of TU and 2TU groups were the same as normal group levels. The contents of serum lactic acid in T group were increased 240% of normal group, but hose of TU and 2TU groups were decreased 38%, 39%, respectively, by glucuronic acid supplementations, compared with that of T group. In conclusion, the effects of glucuronic acids in exercise training rats would appear to reduce peroxidation of tissue as an antioxidative defense mechanism and promote recovery of muscle fatigue.

New exercise technology such as the virtual reality (VR)-based exercise system is required to meet soaring demand for target participants in exercises and to alleviate the difficulties in personnel mobilization through an alternative approach to the exercise system. In a previous study, event tree methodologies were introduced in setting up an exercise scenario of a VR-based radiological exercise system. In the scenario, the locations at which major events occur are rephrased as nodes, routes as paths, and public response actions as protective actions or contents of an exercise at individual locations. In the study, a model for estimating effective doses to the participants is proposed to evaluate the exercise system, using the effective dose rates at particular times and locations derived from a computer program. The effective dose received by a student when she/he follows a successful route is about a half of the dose received when she/he does not follow the exercise guide directions. In addition, elapsed time to finish an exercise when following a successful route is less than one-third of the time spent to finish an exercise when following the guide's directions.

[Purpose] Skeletal muscle glycogen is a determinant of endurance capacity for some athletes. Ginger is well known to possess nutritional effects, such as anti-diabetic effects. We hypothesized that ginger extract (GE) ingestion increases skeletal muscle glycogen by enhancing fat oxidation. Thus, we investigated the effect of GE ingestion on exercise capacity, skeletal muscle glycogen, and certain blood metabolites in exercised rats. [Methods] First, we evaluated the influence of GE ingestion on body weight and elevation of exercise performance in rats fed with different volumes of GE. Next, we measured the skeletal muscle glycogen content and free fatty acid (FFA) levels in GE-fed rats. Finally, we demonstrated that GE ingestion contributes to endurance capacity during intermittent exercise to exhaustion. [Results] We confirmed that GE ingestion increased exercise performance (p<0.05) and elevated the skeletal muscle glycogen content compared to the nonGE-fed (CE, control exercise) group before exercise (Soleus: p<0.01, Plantaris: p<0.01, Gastrocnemius: p<0.05). Blood FFA levels in the GE group were significantly higher than those in the CE group after exercise (p<0.05). Moreover, we demonstrated that exercise capacity was maintained in the CE group during intermittent exercise (p<0.05). [Conclusion] These findings indicate that GE ingestion increases skeletal muscle glycogen content and exercise performance through the upregulation of fat oxidation.

The purpose in the present study was to examine the effects of weight-bearing exercises on stroke patients' ability to perform upper extremity activities. Experiments were conducted with 24 female stroke patients who were randomly assigned to either a control group (CG) that performed general exercise or an experimental group that performed weight-bearing exercise (WBG). The experiments were conducted for 30 minutes per time, three times per week for six weeks. The upper extremity functions, grasping power, and the ability to manipulate the fingers were measured for both groups before the experiments and again six weeks after the beginning of the experiments. Although the scores for upper extremity functions relating to raising the arms that correspond to proximal upper extremity functions increased in both groups, the WBG showed more significant improvement. The WBG showed significant changes in grasping power compared to the CG. Based on these results, weight-bearing exercise can be effective in improving the ability to perform upper extremity movements and grasping power and thus can be used in stroke rehabilitation.
