Abstract

This study investigated the impact of an acute bout of physical activity on postexercise energy intake (PE-EI) in overweight females who were dieting with high restraint (D-HR) and non-dieting with either high restraint (ND-HR) or low restraint (ND-LR). PE-EI at lunch and 12-hours after was compared on the exercise (E) and a nonexercise (NE) day.

There was a significant interaction (F (2,33)= 4.12, p = 0.025) of dieting/restraint status and condition (E vs. NE day) on the 12-hour El. The D-HR ate 519 ± 596 kcal more on the E than on the NE day; while the ND-HR ate 177 ± 392 kcal less on the E than on the NE day.

The results of this study demonstrate that the impact of exercise on PE-EI is determined by both a physiological and psychological response. Dieting status, dietary restraint, level of disinhibition and cognitive factors may influence PE-EI and weight.
