Abstract

 Abstract Introduction & Purpose: Quality of relationship between exercise and APPETITE is important both for people interested in maintaining a healthy body weight and for athletes wishing to optimize performance. The purpose of this study was to survey relationship between changes of APPETITE score with circulating levels of LEPTIN and ACYLATED GHRELIN following a period of STRENGTH TRAINING. Materials & Methods: In a semi-experimental study, twenty one obese young men were randomly placed at two groups: STRENGTH TRAINING (n=10, 26.7±3.3 yr, 96.1±5.5 kg, 31.2±2.9%, 32.6±2.8 kg/m2) and control (n=11, 28.1±3.7 yr, 95.7±5.7 kg, 30.9±3.2%, 32.1±3.7 kg/m2). General characteristics of subjects, circulating levels of LEPTIN and ACYLATED GHRELIN (using ELISA kits), and APPETITE score (using Council on Nutrition APPETITE Questionnaire) were assessed before and after training. STRENGTH TRAINING protocol consisted of twelve weeks weight training (3 sessions per week, 10 stations, 3 sets 8-12 repetitions in each station, intensity 60-80% of one repetition maximum, rest between sets 1 min and between stations 2 min, duration of main training 20-40 min per each session). Data analyzed by SPSS16 software. Statistical significance was accepted at P<0.05. Results: STRENGTH TRAINING decreased serum LEPTIN concentration (8.0±4.1 vs. 6.1±3.6 ng/ml) and increased plasma ACYLATED GHRELIN concentration (15.1±4.6 vs. 18.6±2.8 pg/ml) and APPETITE score (30.4±1.7 vs. 32.3±2.2) (p=0.025, p=0.039, p=0.042 respectively). Also, changes of APPETITE score in STRENGTH TRAINING group were inversely correlated to serum LEPTIN concentration changes (p=0.003), but were directly correlated to changes of plasma ACYLATED GHRELIN concentration (p=0.013, p=0.022 respectively). Conclusion: Performing STRENGTH TRAINING for twelve weeks decreases serum LEPTIN levels, but increases plasma ACYLATED GHRELIN concentrations. These changes are associated with APPETITE improvement. Also, it appears that changes of APPETITE score following training have correlations to changes of LEPTIN and ACYLATED GHRELIN levels (inversely and directly, respectively).
