ACUTE EFFECTS OF EXERCISE ON ENERGY-INTAKE AND FEEDING-BEHAVIOR

The main objective of the present study was to evaluate the short-term effects of exercise of different intensities on energy intake, Eleven young men were submitted to three randomly assigned sessions (one con trol and two exercise sessions) in which they ate, ad libitum, foods f rom a buffet-type meal, The energy cost of exercise was the same in th e two exercise sessions, Results showed that there was no significant change in post-exercise subjective levels of hunger and fullness as we ll as total energy and macronutrient intakes in comparison with the co ntrol session, However, when energy intake relative to expenditure was considered by subtracting the surplus of energy expended during exerc ise from total energy intake, high-intensity exercise exerted a greate r reducing effect on this variable compared with the control and low-i ntensity exercise sessions, These results suggest that for a given lev el of energy expenditure, high-intensity exercise favours negative ene rgy balance to a greater extent than low-intensity exercise.
