It has been claimed that there is a prolonged thermogenic effect of aerobic exercise although the evidence is by no means conclusive. We have therefore studied the thermogenic effect of moderate aerobic exercise in the fasted and fed state in four lean subjects during weight maintenance. Exercise was performed at a constant rate on a bicycle ergometer during the initial 20 mm for four successive hours. The first two exercise periods were in the fasted state while the last two followed an 800 kcal (3.4 MJ) mixed meal. Oxygen uptake increased 22% over the 165 mm after the meal on rest days (p < 0.001). There was a significant but similar elevation of mean 02 uptake during 40 mm postexercise by 13.6% in both the fasted (p < 0.001) and fed state (p < 0.001). Sixty minutes after ceasing exercise mean 02 uptake was not different from preexercise levels (p > 0.05). We conclude that there is no prolonged thermogenic effect of moderate repeated aerobic exercise in weight-maintaining lean subjects. In addition there was no interaction between exercise and dietary induced thermogenesis. [ABSTRACT FROM AUTHOR] |
