Effects Ofa Combined Aerobic-and Muscular Endurance Exercise Program on Body Composition, Blood Profile, Physiological Variables, and Muscle Strength in Middle-aged and Elderly Women during 12 Weeks

The purpose of this study was to investigate the comprehensive alterations on body composition blood profile, physiological variables, and muscle strength, that result from combination of aerobic exercise and muscular endurance training during 12 weeks. Methods in this study; 37 healthy women were involved in subjects. All of them were screened by questionnaire, direct interview, blood profile test, and graded exercise test. They did exercise 3 times sessions per week, programmed with walking and jogging on treadmill and 8 muscular exercises to the local sites of body by free weight instruments. All exercise session have been performed by supervised exercise. Results; Body weight reduced significantly about 1.8kg(p＜.05) after 12 weeks. Middle-aged group was higher reduction of body weight than the other groups. However, there were no significant changes on body fat and lean body mass after exercise. blood glucose in fasting reduced significantly after 12 wks(8mg/dl, P＜.01). Significant reductions in total cholesterol(l8mg/dl, p＜.01) and triglyceride(39mg/dl, p＜.01) were observed post exercise. In case of muscular strength, eccentric contraction increased significantly 8-9 peak force/kg(p＜.05) after 12 wks. but concentric contraction was not after exercise. Physiologic variables such as HR, systolic and diastolic BP, and RPP decreased significantly after exercise, 8 beats/min, 16 mmHg, 9 mmHg, and 4,471 beats/min-mmHg, respectively. and exercise duration time on treadmill was longer 15%(p＜.05) than that of pre-exercise. In conclusion, combine exercise program in this study is effective exercise modality to improve blood profile, physiologic variable, and muscle strength among middle-aged and elder women.
