Physical activity is known to reduce risk of early death through reduction of risk of metabolic syndrome, prevention of weight gain, reduction of abdominal obesity, and increment of bone density. Despite the presence of some physical activity guidelines, a lot of people have been conduct physical activity by their own standards. In the present study, the effects of physical activity that based on arbitrary criteria on the obesity and osteoporosis were investigated. 64 volunteers, who aged over 40 and under 50, were participated. And they were divided into four subgroups(menstruation without exercise, menstruation with exercise, postmenopause without exercise, postmenopause with exercise) to determine the participation of physical activity and menstrual status. In the present results, statistically significant differences occurred in %Fat, abdominal fat ratio, visceral fat area, despite no statistical differences in body mass index in each groups. % Fat, abdominal fat ratio, visceral fat area was increased significantly by menopause, however, physical activity showed the opposite effects. In the blood analysis results were not statistically significant difference occurred. Regression analysis results on visceral fat area showd that age, body mass index, w·aist circumference, triglyceride levels have been identified as a statistically significant, and menstruation showd that T-score and Z-score levels have been identified as a statistically significant. Base on the results of present study, it is suggested that physical activity that conducted by the arbitrary criteria in women after menopause showed positive effects on abdominal fat, and osteoporosis, however for the more obvious effects, increasing calorie consumption and frequency of participation is desirable.
