This study examined the indoor exercise environment use and needs of older adults. The target population was seniors aged 60 years and older living in a newly developed apartment complex. Variables include demographic and housing characteristics, status of exercise, and indoor exercise environmental evaluation and needs. A total of 102 data items were analyzed using frequency, t-test and ANOVA. Noteworthy results are as below. First, community centers and community welfare centers were the most desirable exercise environments because of affordability, exercise programs/spaces. Such exercise environments should be developed in more locations for increasing numbers of seniors. Second, indoor exercise environments need to be improved based on seniors' physical capabilities and environmental behavior. Third, supportive spaces such as restrooms, shower rooms, locker rooms should be carefully designed. Fourth, seniors wanted to have walking trails and indoor swimming pools, the most desirable exercise spaces, within ten to 15 minutes walking distance.

Background: Astragalus membranaceus is a well known oriental medicinal herb. The polysaccharides of the aboveground parts (AMA) and the radix (AMR) of A. membranaceus are the most important functional constituents. Methods and Results: The aim of this study was to determine the effects of AMA and AMR on the oxidative damage induced in the skeletal muscle of rats subjected to exhaustive exercise. Sprague-Dawley rats were randomly divided into exercise and non-exercise groups; in the groups receiving the test compounds, AMA and AMR were administered orally for 30 days. Skeletal muscle samples were collected from each rat after running to exhaustion on a treadmill to determine the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) and the concentation of malondialdehyde (MDA). The antioxidant enzyme activities of SOD and GSH-Px of skeletal muscle of AMA- and AMR-treated groups were significantly higher than those of the control and commercial sports drink (SPD)-treated groups in exhaustive exercise rats. In addition, MDA concentrations in the skeletal muscle of the AMA- and AMR-treated groups were significantly lower than those of the control and SPD-treated groups. In the present study, the effects of AMA and AMR on exercise endurance capacity were also evaluated in mice subjected to a swimming exercise test. AMA and AMR supplementation prolonged the swimming time of mice and enhanced exercise endurance capacity. AMA and AMR possess the ability to retard and lower the production of blood lactate, and prevent the decrease of serum blood glucose. Conclusions: These results showed that, AMR and AMA exerted beneficial effect in mice, increasing the activity of the antioxidant systems and inhibiting oxidative stress induced by exhaustive exercise. The compounds improved exercise performance and showed anti-fatigue effects against exhaustive exercise.

Objectives : This study aimed to evaluate the effect of Wongisaengmaek-san (extracted with water or 50% ethanol) on antioxidative activity and recovery of fatigue induced by weight-loaded forced swimming exercise. Methods : Antioxidant activity of Wongisaengmaek-san was evaluated in terms of total amount of polyphenol, 1.1-diphenyl-2-picrylhvdroxyl (DPPH) radical scavenging activity and xanthine oxidase inhibition. The anti-fatigue effect of Wongisaengmaek-san was investigated using an acute weight-loaded forced swimming test by monitoring swimming test times and blood biochemical parameters creatinine. BUN, lactic acid dehydrogenase (LDH), free fatty acid (FFA) and lactic acid (LA). Results : 1. 50% EE (ethanol extract) had 2.3 times higher amount of total polyphenol compared to water extract. 2. It was identified that 50% ethanol extract showed enhancement of xanthine oxidase inhibition and DPPH scavenging effect in vitro. 3. According to anti-fatigue effect in the scale of 5% weight loaded mouse swimming test, both water and 50% ethanol extract showed significant improvement of swimming time elongation respectively, and 50% ethanol extract induced a more positive result. 4. After swimming for 1% weight-loaded mouse. water extract and 50% ethanol showed significant anti-fatigue effect with manifestation of blood sampling among both of the intervention: 50% ethanol extract showed a greater result. Conclusions : 50% ethanol extract of Wongisaengmaek-san has more effective antioxidant activity and anti-fatigue than water extract.

The purpose of this study is to investigate the dietary intake and bone mineral density(BMDs) in college women(n = 10), female swimmers(n = 10), and female weight lifters(n = 10). BMDs of lumbar spine(L2-L4), femoral neck, ward's triangle, and trochanter were measured with dual-energy X-ray absorptiometry. The results are summarized as follows. In swimmers and weight lifters, mean daily intakes of energy, protein, and fat were higher than those of college women and the intake of carbohydrate was significantly high in weight lifters. Also in swimmers and weight litters, mean daily intakes of animal flood, phosphorus, vitamin A, vitamin B$_1$, vitamin B$_2$, niacin, vitamin C, and cholesterol were found higher than those of college women but there was difference among the types of exercise. According to correlation analysis between nutrient intake and BMDs, intakes of energy, protein, carbohydrate, and vitamin B$_1$ were positively associated with BMDs of lumbar spines. According to stepwise multiple recession analysis, BMDs of lumbar spines were affected by intakes of protein, Fe, phosphorus, and vitamin B$_2$, also BMDs of femur were affected by each of vegetable protein, dietary fiber, and fe. from the above explanation, the nutrient intakes can be independent factor besides exercise. In conclusion, the weight lifting, resistant exercise, resulted in increase of both BMDs of lumbar spines and femur specially in growing and adult period of female. Whereas swimming lead to increase of BMDs of lumbar spine and decrease of BMDs of femur in female.

Rhodiola rosea is a perennial plant which grows in the alpine regions of Europe and Asia. Although the protective effects of R. rosea extract from fatigue due to exercise stress have been reported, studies on fermented R. rosea extract remain insufficient to date. Therefore, this study was conducted to examine the protective effects of fermented R. rosea extract against fatigue and exercise stress. As a result, fermented R. rosea extract was found to significantly increase swimming time, hepatic superoxide dismutase content, and serum lactate dehydrogenase in mice, while decreasing serum blood urea nitrogen content compared to R. rosea extract. Given the above results, it is considered that fermented R. rosea extract effectively protects against fatigue caused by strenuous exercise.

This study was designed to investigate the effects of an aquatic exercise program on the physical function and depression among the community elderly. The subjects were 41 cases of aged over 65 who went to elderly college in Hawsung-Kun, Kyeongkee province. Seventeen of them were assigned to control group, while twenty four subjects to the experimental group. The period of data collection was from June., 1999 to November., 1999. The aquatic exercise program was developed by the author with the assistance of rehabilitation medicine doctor and physical therapist in the public health center. The program was carried out once a week for 6 months in regular swimming pool. Data were analyzed with t-test, $X^2$ test, ANCOVA. paired t-test using SAS 6.12. Results were obtained as follows: 1. The increments in the range of motion of the shoulder and knee joints in experimental group after exercise was significantly greater than those in the control group. 2. The physical pain score decreases significantly after the exercise in the experimental group only. 3. The experimental group revealed lower level of depression after exercise than the level before the exercise, whereas control group showed no significant changes in this level. These findings may indicate that the aquatic exercise program is effective in increasing the range of motion of shoulder and knee joints and also effective in decreasing pain, the level of depression. Accordingly. the aquatic exercise program can be adopted as an health promotion program for community elderly.

Sasang Constitutional Medicine (SCM) is based on the theory of Sasang (Taeyang, Soyang, Taeum, Soeum) in Traditional Korean Medicine (TKM). It is hypothesized that all of the things in the material world can be divided into the four categories of SCM. We made a new attempt to combine nutritive components, and patterns in physical activities with SCM. At first, we hypothetically divided the nutrients into 4 compartments according to SCM theory, and human body composition as well. These factors could be basically related to Sasangin Exercise Treatment (SET). Therefore, we applied sasangin theory to exercise prescription. As a research method, we hypothesized that human beings' types can be distinguished by mind and body. Mind was focused on exercise psychological aspects, and body also handled by nutrients, body compositions, body shapes, and exercise physiological aspects. For application of sasang theory to the exercise prescriptions, Taeumin as a sample sasangin was selected in this study. We concluded that in perspective of general traits, Taeumin have to reduce their carbohydrate intake volume, but greatly increase their intake of vitamins, minerals, and water in daily diet. They are also recommended exercises that can increase cardiorespiratory function and make them sweat, like endurance running, hiking, swimming, cycling, etc.

Purpose: This study was conducted to explore the experiences of women with osteoarthritis in the community-based aquatic exercise program. Methods: A total of 13 women who lived urban-rural complex areas participated in 8 weeks of aquatic exercise. Data were collected from two focused group interviews of those who signed informed consent. Results: Four categories emerged from the contents analysis: 1) assisting a remedial program (participant-centered education, alleviation of physical symptoms, and relieving stress), 2) Pleasure of being together (group exercise, feeling of pleasure and joy, and strong and confident supporter), 3) burden of participation (economic burden, low accessibility and unaccustomed swimming pool), 4) organizing and activating a self-help group(acquired confidence over exercise, hoping for continue exercise, and Needs of self-help meeting). Conclusion: Aquatic exercise was good for women living urban-rural area as it gave not only reliving arthritic symptoms but also improving social relationships. It is optimal to assist in making of a self-supporting group and continuing activities through it.

Menopause and obesity are associated with metabolism. The purpose of this study was to examine the changes of PPAR${\gamma}$, PGC-1(${\alpha},\;{\beta}$), NRf-1 and TFAM mRNA and mitochondria biogenesis in adipocytes and investigate the effect of swimming exercise for 6weeks on ovariectomized rats. Rats were randomly assigned to 3 groups: (1) ovariectomized rats fed with a control diet (C, n=4), (2) ovariectomized rats fed with high fat diet (H, n=4), and (3) ovariectomized rats trained to exercise and fed with high fat diet (H+EX, n=4). Exercise was performed by swimming for 5 days/wk, with a progressive increase in exercise over the course of 6 weeks. Results showed that the fat tissue weight in the H group was markedly increased (p<0.01) compared to other groups, however, regular exercise significantly decreased fat weight. The PPAR-${\gamma}$ (p<0.05), PGC-$1{\alpha}$ (p<0.01), -$1{\beta}$ (p<0.05), NRf-1 (p<0.01) and TFAM (p<0.05) mRNA expression in the adipocytes of H+EX were higher than in the H group. These results suggest that regular exercise for 6 weeks might exert positive effects by increasing PPAR-${\gamma}$, PGC-1 (${\alpha},\;{\beta}$), NRf-1 and TFAM mRNA expression and mitochondria in adipocytes. Thus, regular exercise may be helpful in the improvement of mitochondria biogenesis function in obese, ovariectomized rats.
