Effect of exercise intensity on body composition in overweight and obese individuals: A prospective study
Journal Title: Medpulse International Journal of Physiology - Year 2018, Vol 7, Issue 3
Abstract
Background: Obesity is a major health problem due, in part, to physical inactivity. The amount of activity needed to prevent weight gain is unknown. Exercise is an important component of weight loss program. Recently, high intensity exercise done for less duration is emerging and gaining importance. Our aim was to investigate the intensity of exercise required to produce a significant change in anthropometric and body composition measurements. Materials and Methods: Volunteers, sedentary overweight and obese in the age group of 19-35 years, were randomized into group I (n=30) those performing moderate intensity exercise at 50-74% of heart rate maximum reserve for 40 min and group II (n=30) high intensity exercise at 75%-84% of heart rate maximum reserve for 20 min on a bicycle ergometer for a duration of 15 weeks. Skin fold calliper was used for anthropometry. Results: There was a significant change in the weight, waist hip ratio, skin fold thickness, circumference measures, fat mass, fat percentage, and lean body mass among moderate (p<0.05) and high intensity group (p<0.05). A significant change in fat mass (p<0.05) lean body mass (p<0.05) and fat % (p<0.05) in the high intensity group compared to moderate intensity group was observed. Conclusion: It is concluded that 15 weeks of exercise at high intensity is more effective in changing the body composition in overweight and obese individuals.
