Effect of Aerobic Exercise Training on Energy Expenditure by Physiological Cost Index in Obese Individuals

Abstract

Aim: To find the effect of aerobic exercise training on energy expenditure by physiological cost index in obese individuals. Background: Obese individual tend to expend more energy in any particular task as compared to normal weight individuals. Aerobic exercise has been the subject of investigation to improve energy expenditure. Methodology: This was an experimental pre/post study. 30 obese individuals between the age group of 18-28 years were included in the study. All the 30 individuals were divided in a group of 5 each. The difference of pre to post PCI week 1 of each subjects was calculated before the exercise programme. The individuals then underwent a group aerobic exercise training,training was imparted for 3 days for 4 consecutive weeks. The training program included warm up, training phase and cool down. The difference of pre to post PCI week 4 was then calculated. The data was statistically analyzed using student paired t test. Results: Aerobic exercise showed a significant decrease in the physiological coast index after 4 weeks. (p = <0.0001*). Conclusion: A 4 week aerobic exercise training is effective in improving energy expenditure in obese individuals.
