Background: Ginseng has been used as an ergogenic agent, although evidence for its effectiveness is weak. A randomized, double-blind, placebo-controlled clinical trial was conducted to evaluate the effect of a ginsenoside complex (UG0712) on changes in exercise performance. Methods: Sedentary individuals (n = 117) were randomly assigned into one of three groups: low-dose ginsenoside supplementation (100 mg/d, n = 39), high-dose ginsenoside supplementation (500 mg/d, n = 39), or a placebo group (500 mg/d, n = 39). All participants underwent a supervised 12-wk aerobic and resistance exercise training course. To assess the effects of supplementation on physical performance, maximal oxygen consumption ($VO_2max$), anaerobic threshold (AT), lactic acid, and muscle strength of the dominant knee were measured at baseline, every visit, and after the training program. Results: Both ginsenoside groups showed significant increases in $VO_2max$ and muscular strength during exercise training. There were no definite changes in AT and lactic acid levels over time. After exercise training, there were definite differences in the $VO_2max$ (28.64.9 to $33.7{\pm}4.9ml/kg/min$ in high-dose group vs. $30.4{\pm}6.7$ to $32.8{\pm}6.6ml/kg/min$ in placebo, p = 0.029) and AT ($19.3{\pm}4.2$ to $20.9{\pm}3.5ml/kg/min$ in high-dose group vs. $20.0{\pm}5.1$ to $20.0{\pm}4.9ml/kg/min$ in placebo, p = 0.038) between the high-dose ginsenoside and placebo groups. However, there was no difference in $VO_2max$ between the low-dose ginsenoside and placebo groups (p = 0.254). There were no differences in muscular strength during exercise training among the three groups. Conclusion: High-dose ginsenoside supplementation (UG0712) augmented the improvement of aerobic capacity by exercise training.

The purpose of this study was to analyze the effect of different types of rehabilitation training program on the kinetic and kinematic parameters during sit-to-stand movement(STS) in chronic stroke patients. Two groups of hemiparetic patients, experimental and control, participated in the study. The experimental group participated in a 10-week training program (three sessions/wk, $1{\sim}1.5\;hr/session$) consisting of a warm-up, aerobic exercises, lower extremity strengthening. and a cool-down. The control group participated in an aerobic exercise. Three dimensional kinematic analysis and force platform; were used to analyze the duration of STS, lower extremity angle, and weight bearing ability. The experimental group which had more strength of lower extremity displayed decrease in duration of STS. However, the control group showed increases in duration during sit-to-stand movement. The control group flexed their trunk more than the group did Therefore, it took more time to extend their trunk during STS. The duration in sit-to-stand was affected by the strength of lower extremity and the angle of trunk movement. The angles of ankle and knee joint had an influenced on duration of STS. The post experimental group performed with their feet near the front leg of the chair during sit-to-stand, therefore the duration was decreased. The repetitive sit-to-stand movements as a resistance exercise was effective to hemiparetic patients in learning mechanism of sit-to-stand. The control group showed decreased differences in the vertical ground reaction forces between paretic and non-paretic limbs. Their training program included strengthening exercise that may help improving weight bearing ability. The control group showed increases in the center of pressure in the anteroposterior and mediolateral displacement. This means that the stability of movement was low in the control group. Their training program which combined aerobic and strengthening exercises that are more effective to improve the stability of movement.

The purpose of this study is to investigate the effects of indoor and outdoor exercise environments on bone mineral density and body composition in old women. A total of 26 old women were randomly divided into two groups: an indoor exercise group (IE, n=13) and an outdoor exercise group (OE, n=13). The exercise groups performed moderate exercise (HR max 50~70%; RPE 11-15) three times a week for 60 minutes over 20 weeks. After exercise training, bone mineral density was significantly improved in the OE group as compared with the IE group. Body fat mass was significantly decreased in the IE group. Weight, lean body mass, and body fat mass were significantly decreased in the OE group. Body mass index was significantly decreased in the outdoor exercise group as compared to the IE group. Our findings show that a 20-week program of outdoor exercise training improves bone mineral density and body composition in old women. As mentioned above, it has been found that engaging in an outdoor exercise program for 20 weeks has a positive effect on bone mineral density and body composition in old women. In conclusion, engaging in the outdoor exercise program, including aerobic and resistance exercises, for 20 weeks improved bone mineral density and inhibited bone loss in old women and had a positive influence on vitamin D levels, thereby potentially lowering the risk of osteoporosis.

The purpose of this study was to investigate the effect of either endurance training only or endurance and weight training on muscle morphology and oxidative enzyme activities in human skeletal muscles. Fourteen healthy males were randomly divided into one of two experimental training groups, either swim exercise training (n=7, ST) or combined exercise training (swim and resistance exercise training; n=7, SWT). The change of muscle fiber type was not significantly different between ST and SWT following 6 weeks of exercise training. Mean cross sectional areas as well as the numbers of capillary of different types of muscle fiber were not also significantly different from baseline for both exercise training groups (p>.05) although the tendency of increase were more notable in SWT. All oxidative enzyme activities (i.e., ${\beta}$-hydroxyl acyl dehydrogenase, citrate synthase, and carnitine palmitoyl transferase) were marginally higher in SWT compared to ST even though statistical power did not reach the level of significance. Based on these results, it was concluded that performing of combined (swimming and weight) exercise training could be the better modality for improving muscle morphological changes and oxidative enzyme activities than performing of only single aerobic exercise intervention in young healthy human skeletal muscles.

The purpose of this study is to analyze how the ten-week complex exercise program for obese postpartum women affects their metabolic syndrome related risk factors (HDL-C, TG, Glucose, blood pressure, and waist circumference) and adipocytokines (Leptin and Adiponectin). The study subjects were 14 women who passed less than 40 months after their child birth, among whom seven were assigned to complex exercise group and seven to control group. The complex exercise program consists of rhythm dance aerobic exercise and resistance exercise. It has been performed twice a week for 10 weeks, and 80 minutes for each session. For data analysis, Mann Whitney U-test, Wilcoxon test, Spearman correlation analysis were conducted. As a result, the groups had no difference in all of the metabolic syndrome related risk factors before and after the program. Regarding intra-group difference, the complex exercise group significantly increased HDL-C, and significantly decreased TG, Glucose, and waist circumference, and the control group signfiicantly increased TG and Glucose. According to the analysis on adipocytokines, in terms of intra-group difference, the complex exercise group significantly increased Adiponectin after exercise. With regard to the correlations between metabolic syndrome related risk factors and adipocytokines, HDL-C and Glucose had a correlation with Adiponectin.

The purpose of the study was to assess the effects of a 12 weeks aged garlic extract (AGE) regimen with regular exercise on cardiovascular disease (CVD) risk in postmenopausal women. A total of 30 postmenopausal women ($54.4{\pm}5.4$ years) were randomly divided into the following four groups: Placebo (Placebo; n = 6), AGE intake (AGEI; n = 8), exercise and placebo (Ex + Placebo; n = 8), exercise and AGE (Ex + AGE; n = 8) groups. The AGE group consume 80 mg per day, and exercise groups performed moderate exercise (aerobic and resistance) three times per week. After 12 weeks of treatment, body composition, lipid profile, and CVD risk factors were analyzed. Body weight was significantly decreased in AGEI, Ex + Placebo, and Ex + AGE groups compared to baseline. Body fat % was significantly decreased in the AGEI and Ex + Placebo groups. Body mass index (BMI) was significantly decreased in the AGEI, Ex + Placebo, and Ex + AGE groups. Fat-free mass was significantly decreased in the AGEI group. Total cholesterol (TC) was significantly lower in the Ex + Placebo compared to the Placebo group. AGE supplementation or exercise effectively reduced low-density lipoprotein (LDL-C). Triglyceride (TG) was significantly increased in the AGEI group. Malondialdehyde (MDA) levels were significantly decreased in the AGEI, Ex + Placebo, and Ex + AGE compared to the placebo group. AGE supplementation reduced homocysteine levels regardless of whether the women also exercised. The present results suggest that AGE supplementation reduces cardiovascular risk factors independently of exercise in postmenopausal women.
