Acute interval exercise intensity does not affect appetite and nutrient preferences in overweight and obese males

ورقة مؤتمر

This study investigated the influence of two different intensities of acute interval exercise on food preferences

and appetite sensations in overweight and obese men. Twelve overweight/obese males (age=29.0±4.1 years; BMI

=29.1±2.4 kg/m2) completed three exercise sessions: an initial graded exercise test, and two interval cycling sessions:

moderate-(MIIT) and high-intensity (HIIT) interval exercise sessions on separate days in a counterbalanced

order. The MIIT session involved cycling for 5-minute repetitions of alternate workloads 20% below and 20%

above maximal fat oxidation. The HIIT session consisted of cycling for alternate bouts of 15 seconds at 85%

VO2max and 15 seconds unloaded recovery. Appetite sensations and food preferences were measured immediately

before and after the exercise sessions using the Visual Analogue Scale and the Liking & Wanting experimental

procedure. Results indicated that liking significantly increased and wanting significantly decreased in all food

categories after both MIIT and HIIT. There were no differences between MIIT and HIIT on the effect on appetite

sensations and Liking & Wanting. In conclusion, manipulating the intensity of acute interval exercise did not affect

appetite and nutrient preferences.
