Abstract:

This study investigated the effects of different acute exercise mode on subjective hunger rating. Ten healthy woman subjects participated voluntarily in the study and written informed consent was obtained from all subjects before participation. Subjects undertook four, 1,5 h trials (3exercises and 1 control) in a randomized crossover design. In the exercise trials subjects were performed three different exercise protocol (resistance, resistance+endurance, endurance). In the control trial, subjects rested for 1,5 h. Ratings of subjective feelings of hunger was reported on 100 mm visual analogue scales (VAS) at baseline (-20) and at 0, 20, 40, 60 and 90 mins after baseline. Repeated-measures, two factor ANOVA was used to examine differences between the four trials over time for hunger change. Between-trial differences at each time point were examined using repeated measures ANOVA and Bonferroni post hoc tests when significant interactions were found. Two-way ANOVAs revealed significant trial (p=0.047) trial x time effects (p=0.041) and time (p=0.000) effects for hunger. Endurance+resistance exercise trial increases the feeling of hunger more than resistance exercises trial (p=0.021) and control trial (p=0.046). In conclusion, acute resistance+endurance exercise increases appetite in healthy woman.
