Abstract

Abstract: Objective: To investigate the effects of 12-week low intensity aerobic exercise on the body composition, haemodynamics and exercise endurance of the male old patients with simple obesity, and to provide evidence for conducting special exercise prescription. Methods: Forty-six male old simple obesity patients were divided into control group (n=19) and exercise group (n=27) according to subjective will. The subjects in control group maintained daily life while those in exercise group performed a 12-week low intensity aerobic exercise. Before and after experiment, the rest heart rates and blood pressures were measured, the maximal oxygen intake (VO_2max), maximal power (MP) and exhaust time (ET) were detected by symptom limited graded exercise test, the heart rate curve and blood pressure curve were depicted, and the body composition was determined by body composition analyzer. Results: Compared with before experiment, the fat mass, the percentage of fat body, rest heart rate and blood pressure of the patients in exercise group were decreased (P<0.05), the VO_2max, MP and ET were increased (P<0.05), and the heart rate curve and blood pressure curve during exercise test shifted right; but the indicators in control group showed no significant changes (P>0.05). Compared with control group, the fat mass, percentage of body fat, rest heart rate and blood pressure were decreased (P<0.05) and the VO_2max, MP and ET were increased (P<0.05) in exercise group after experiment. Conclusion: Low intensity aerobic exercise of 12-week may effectively improve the haemodynamic abnormality, reduce the body composition and enhance the exercise endurance.
