And further, after the cycling session was over, the men rated themselves as hungrier than they did after the control trials, but after the rope-skipping sessions, they did not. This suggests that cycling, but not jumping rope, causes hunger that leads to "compensating" for the energy that was burned, the researchers said.
However, the gut hormone levels were not different after the cycling sessions compared with the rope-jumping sessions. It may be that some other mechanism explains the difference in hunger levels, the researchers said.
"Taken together, our results suggest that aerobic exercise, particularly rope-skipping exercise, may regulate the desire to eat fatty foods, and thus improve dietary behavior regarding fatty foods in adults," they said.
Barry Braun, associate professor and director of the energy metabolism laboratory at the University of Massachusetts, said that the study was well-designed in that the researchers matched the energy expended between the rope-skipping versus cycling conditions.
