Oxygen Consumption In Obese Individuals

One minute incremental maximal exercise test was carried out on a motorized treadmill in nineteen obese individuals (10 men, 9 women) and nineteen normal healthy volunteers (9 men, 10 women) for their oxygen consumption. The results indicate that there was no significant difference in oxygen consumption in relation to their body weight and lean body mass in both the groups during submaximal exercise. At maximal exercise the VO2 max in relation to body weight was significantly lower in obese men and women. Lower Oxygen consumption in relation to body weight at maximal exercise could be due to lesser percentage of lean body mass (LBM) proportional to body weight.
