The aim of the study was to identify the effects of a social-support-based walking program for residents in rural areas. Data were collected from 120 residents who are residential in Chungcheongnam-do and participated in walking program at community health centers from March and September 2013. Collected data included body mass index, body fat mass, and skeletal muscle mass and physical Activity. The data were analyzed using a paired t-test with SPSS19.0. This study showed that a 7-month walking program had positive effects on the physical health index, representing reductions in the body mass index(t=-12.418, p<.001), body fat mass indes(t=13.031, p<.001) and an improvement in the skeletal muscle mass(t=-12.642, p<.001). Health behavior index; dietary practice guideline score(t= -4.324, p<.001), physical activity day(t=-8.715, p<.001), high risk drinking day(t=6.298, p<.001) were improved through walking program. These results indicated that the walking program for the community was effective in improving the health status of the participants. Therefore, I suggest that the development and running of various social-support-based walking program be required by applying the results.

The purpose of this study was to examine the effect of Yoga and Pilates training on the obesity indexes, muscle mass in each body part and physical fitness of male college students in an effort to provide some clinical information on exercise prescription. The subjects in this study were 20 selected obese male students. A yoga group and a pilates group were organized with 10 students each, and the training was provided for 12 weeks, 5 times a week, 90 minutes each. The findings of the study were as follows: First, both of yoga and pilates made significant differences to obesity indexes(an increase in skeletal muscle mass, a decrease in BMI, a decrease in body fat rate and a decrease in WHR), to muscle mass in each body part(an increase in muscle mass on the right arm, left arm, trunk, right leg, and left leg), and to physical fitness(an increase in lower extremity muscle strength, muscular endurance, flexibility, left balance and right balance). Second, pilates exercised a more signifiant influence than yoga on an increase in skeletal muscle mass, the improvement of muscle mass in each body part(an increase in muscle mass on the right arm, left arm, trunk, right leg and left leg), and the improvement of balance(left and right). Third, yoga had a more significant impact on a decrease in BMI, body fat rate and WHR. Given the findings of the study, yoga and pilates seem to be efficient exercise programs to improve the obesity indexes of obese male college students and promote their health.

The body composition and arterial compliance with advanced age increase the risks of cardiovascular diseases, but the elderly can perform rhythm exercise easily, which may positively influence their body composition and arterial compliance. Therefore, this study examined the effects of rhythm exercise training on the body composition and arterial compliance in elderly females. The subjects (n=20) were assigned randomly to either an exercise group (n=10, EX) or non-exercise control group (n=10, CON). The rhythm exercise training for 12 weeks consisted of 3 sessions per week with 60 minutes per session. In addition, the intensity was set to 11-14 of the Borg scale (6-20). The body composition and arterial compliance (pulse wave velocity (PWV)) were measured before and after training. The skeletal muscle mass in the EX was increased significantly (p=0.04) and the right (p=0.002) and left side (p=0.02) of the PWV in the EX were decreased significantly, but the skeletal muscle and both sides of the PWV in the CON were not changed. Elderly females could easily perform rhythm exercise training, which resulted in improvements of the skeletal muscle mass and arterial compliance. Therefore, rhythm exercise training may prevent or delay sarcopenia and reduce the risk of cardiovascular diseases.

The purpose of this study was to obtain baseline data on nutritional management of women's bone health. We examined the bone mineral density (BMD) by ultrasound bone densitometer, anthropometric measurement and dietary intake to assess the nutrient intakes. The subjects were 102 Korean female college students (normal=59, bone disease group [osteopenia+osteoporosis]=43) and the mean age was 21.4 yr. Mean T-score (BMD) were -0.42 and -1.52 in normal and bone disease groups, respectively. Anthropometric measurement showed that 59% of the subjects were normal weight and bone disease group had lower value than normal group in majority of anthropometric index. The average energy intake was 1539.7 kcal, which was 73% of Korean EER. The subjects had lower vitamin C, folic acid, Ca and K intake than Korean RI independent of BMD. Bone disease group (1:2.05) showed significantly lower Ca:P ratio than normal group (1:1.86). Normal group had more intake frequency of milk and milk product than bone disease group. In relation to anthropometric index with T-score, significant correlations have been found in weight, PM, BFM, MM, TBW, SLM, FFM WHR, BMI and SMM. In relation to dietary factors with T-score, significant correlations have been found relating to intake frequency of milk and milk product. Our results indicate that for nutrients, ratio and balance may be more influential than intake for bone health in young women.

This study investigated the effect of cold acclimatization training on body composition including weight, fat mass, and muscle mass with 10 subjects (5 males and 5 females). During the 3-week acclimatization training program, they visited an artificial climate chamber ($15^{\circ}C$) 15 times and were exposed to cold environment with light clothing for 2 hours. Body composition was measured before and after cold training using bioelectric impedance analysis that was later compared by a paired t-test. In the process of thermoregulation, muscle contraction was accompanied by increased substrate metabolism for rising heat production. After cold training, the muscle mass increased and fat mass decreased significantly (p<.1, p<.05), subsequently the body composition changed. It was found that cold acclimatization training could be used as a treatment for obesity. It was suggested that further investigation on the long term effects of mild cold exposure using clothing and its potential applicability as an obesity treatment.
