ABSTRACT |
The purpose of this study was to examine the changes of body composition, concentration of blood lipid, diet and metabolic hormone by aerobic exercise durations (30 min, 60 min; 60-65 %HRR). Data were collected three times a week for 12 weeks. We found results as follows: there was no interaction in any factors between two groups and the periods before and after the exercise. The substantial changes in body fat mass (p<.05), % body fat (p<.05), WHR (p<.05) and concentration of TG (p<.05), TC (p<.01), LDL-C (p<.05) and leptin (p<.05) clearly demonstrated significant effects of the period before and after an aerobic exercise. Moreover, one-hour main exercise group showed more significant decrease in % body fat, TC and leptin concentration in comparison of pre- and post-exercise. In sum, no statistically significant changes were found in many dependent variables; however, the researchers could have found the changing tendency that may be caused by regular exercise. The study, therefore, demonstrated that women beginning menopause can bring as much positive physical changes through regular aerobic exercise, which is recommended by the study, 30 minute in moderate intensity, three times a week for 12 weeks. From this perspective, the women in this period absolutely benefit from participating in physical activities. The findings of this study suggest that further researches should take different approaches and try to find the effect of exercise duration based on exercise intensity, frequency, type, and term. |
