Abstract/OtherAbstract:
The purpose of this study was to investigate the changes of maximal oxygen consumption, left ventricular function and serum lipids after 36 weeks of aerobic exercise in elderly women without the influence of drugs. Eight elderly women were studied by M-mode and Doppler echocardiography to assess left ventricular size, mass and function. Maximal oxygen consumption (VO(2)max) was determined for each subject by administering a treadmill exercise test. The training intensity was decided by heart rate reserve. Subjects performed exercise for 40 minutes a day, 3 days a week at 50-60% of the heart rate reserve during the 36 weeks. Exercise capacity was assessed by VO(2)max with a graded exercise test of the treadmill. Weight and % body fat decreased after training. Cardiorespiratory function improved because of the increase in VO(2)max and VO(2)max normalized for body weight after training. Systolic blood pressure significantly decreased. There are no significant difference in all left ventricular's parameters (end-diastolic dimension, end-systolic dimension, end-diastolic volume, end-systolic volume, stroke volume, cardiac output, ejection fraction, fractional shortening) after 36 weeks. Exercise training did not induce left ventricular (LV) enlargement as evidence of an absence of increase in left ventricular end-diastolic volume. The total cholesterol level and triglyceride level decreased after training. High density lipoprotein-cholesterol significantly increased and low density lipoprotein-cholesterol significantly decreased, atherogenic index (AI) significantly decreased and apolipoprotein A-I increased and apolipoprotein B decreased after training. In conclusion, although there was no significant change in left ventricular function, aerobic training showed a positive influence on body composition, maximal oxygen consumption and serum lipids.
