INTRODUCTION:
The impact of resistance exercise (RE) on appetite and food preference has been extensively investigated, yet studies addressing gender differences in this area remains relatively sparse. This study aimed to examine gender differences in subjective appetite and food preference subsequent to RE.
METHODS:
Eighteen healthy male participants (age = 22.9 ± 1.9 years, body mass = 22.8 ± 2.0 kg/m2) and eleven healthy female participants (age = 22.6 ± 1.3 years, body mass = 22.8 ± 2.1 kg/m2) were recruited in this study. Participants completed a RE trial (3 sets with 70% 1RM) and a control trial (no exercise) in a randomized crossover design. Subjective appetite ratings (hunger, fullness, satisfaction, prospective food consumption, and nausea) were evaluated before exercise and 90 minutes after exercise (post 0, post 30, post 60, post 90). Leeds Food Preference Questionnaire was measured at post 30 and 90 and after ad libitum meal (about 120 minutes after exercise).
RESULTS:
Subjective prospective food consumption and overall appetite at post 0 were significantly lower than before exercise (p < .05), but no differences were found between males and females (p > .05). For food preference, explicit liking of low-fat sweet food (LFSW) and explicit wanting of high-fat sweet food (HFSW) at post 30 were significantly higher in males than in females (p < .05). Females showed a significantly higher preference of explicit liking and wanting of LFSW at post 120 than males. There were no significant differences in explicit wanting and implicit wanting for fat and taste bias (p > .05).
CONCLUSION:
No gender differences were found in terms of RE-induced appetite suppression. Changes in food preferences were found between males and females after RE and meal.
