BACKGROUND: This study aimed to analyze the effects of high-intensity intermittent training (HIIT) plus strength training on body composition, hormone related to energetic balance (leptin), and hunger scores in physically active non-obese men.
METHODS: Sixteen men were allocated in two different groups, training group (n=10) performed a combined HIIT (5 km, 1 min of effort interspersed by 1 min of rest in passive recovery) followed by strength exercise session (three sets, with load of 8-12 repetition maximum) twice a week, during 8 weeks, while control group (n=6) did not suffer any intervention. Hunger scores, leptin concentrations and body composition were assessed. Body composition, fasting leptin and hunger score were compared through two-way analysis (group and period) with repeated measures in the second factor while leptin and hunger scores in exercise session pre- and post-8weeks through two-way analysis (period and time of measurement) with repeated measures in the second factor.
RESULTS: The fasting leptin decreased pre- to post-8week in training group (7.7 ± 4.9 to 2.9 ± 2.1 ng/ml; p = 0.012). For leptin response to exercise session there was main effect of training period, with higher values pre- (6.5 ± 3.9 ng/ml) than post-training (2.6 ± 2.1 ng/ml; p < 0.001). For hunger scores there was effect of time of measurement (p <0.001), decreasing after breakfast and increasing over the experiment.
CONCLUSIONS: Combined HIIT plus strength training were able to promote alterations in a hormone related to energy balance independent of body composition and hunger index alterations in physically active non-obese men.
