The purpose of this study was to investigate the changes of body composition and serum lipid after 12weeks aerobic exercise. Subjects were composed of fourteen hypertension elderly women without regular exercise habit. HRmax was determined for each subjects by administering a treadmill exercise test. The exercise intensities are decided by regression equations between %HRmax and speed(m/min). Subjects were exercise during 12weeks(50% HRmax, 4 frequencies /week, 1 hour/day), t-test was used to evaluate the difference of the pre and post exercise. The .05 level of significance was as critical level for this study. The conclusion of this study were as follows ; 1. Weight and %fat were decreased after 12weeks aerobic exercise. 2. Systolic blood pressure and diastilic blood pressure were decreased after 12 weeks aerobic exercise. 3. TC, TG and LDL-C were decreased and HDL-C was increased ater 12weeks aerobic exercise. In conclusion, Aerobic exercise was shown to positive influence on body composition, and serum lipoproteins. so it may help to prevent cardiovascular disease in elderly women.
