Obesity Does Not Modulate Men'S Eating Behavior After A High Intensity Interval Exercise Session: An Exercise Trial

BACKGROUND: We investigated the impact of obesity on responses to high intensity interval exercise (HIIE) on hunger and energy intake (EI) in young men.METHODS: Ten men with obesity (OB) (Body Mass Index [BMI]: 34.6 +/- 4.4 kg/m(2)) and 10 with normal weight (CG) (BMI: 23.1 +/- 3.9 kg/m(2)) participated in a HIIE session. The session consisted of 6 rounds performed at 100% of maximum aerobic velocity (MAV) for 30 seconds, followed by 30 seconds of active recovery at 50% MAV and concluded with 4 minutes of passive recovery. This was repeated three times. El was estimated at baseline and 24 h-post-HIIE. Hunger was measured at baseline. 2 h- and 24 h-post HIIE.RESULTS: Carbohydrate (CHO) intake increased in both groups (P<0.01). Hunger feelings (19.5 [0-50] mm at baseline to 50 [9-73] mm post-2 h and 60 [8-92] mm in post-24 h [group: P=0.71, time: P<0.01, group x time: P=0.06]) and a desire to eat (34 [1-89] +/- 36.0 mm at baseline to 63 11-861 mm post-2 h and 51 [7-84] mm post-24 h [group: P-0.65. time: P<0.01. group time: P-0.29]) increased in both groups.CONCLUSIONS: Weight status does not modulate hunger and EI post-HIIE. However, the compensatory increase in CHO intake and hunger feelings is particularly noteworthy for health professionals.
