- Abstract
Introduction: Aerobic exercise is a physical exercise that is performed at moderate level of intensity over a relatively longer period of time. It depends primarily on aerobic energy generating process. There is a direct correlation between physical inactivity and cardiovascular morbidity and mortality. In this study, we show effect of aerobic exercise on parasympathetic function in healthy young adult. Aim of this study is to quantify parasympathetic function in study and control group before and after 3 months of aerobic exercise. Material and method: The present study was carried out at autonomic function test laboratory in the department of physiology, K. G. M. U., Lucknow, after ethical clearance. 60 apparently healthy untrained male subjects with normal physical activity and BMI18.5-24.5 kg/m2, aged 18-35 years were enrolled in this interventional study and divided into 2 equal groups, exercise and control group. 30 subjects of exercise group performed aerobic exercise by running on treadmill (20 minuts, alternate day) for 12 weeks and 30 subjects of controlled group continued sedentary life style. To quantify parasympathetic function, following parameters were measured: [1) Heart rate response to standing from supine position (30:15 ratio). 2) Heart rate response to slow deep breathing (E:I ratio). 3) Heart rate response to Valsalva maneuver] of all the subjects were recorded at day 1 and after 3 months, with the help of PC based cardiac autonomic neuropathy analysis system. Result: Parasympathetic functions (30:15 ratio, E:I ratio, and Valsalva ratio) are found to be significantly higher in exercise group as compared to control group. Significant differences were found in the above mentioned parameters among the exercise group but no significant change was observed among control group. Conclusion: The study suggests that parasympathetic function shows favorable changes with aerobic exercise.
