摘要：The purpose of this study was to investigate exercise induced variation of leptin,acyl-ghrelin and obestatin hormone concentrations in transition,preparation and competition training periods in elite prepubertal female gymnasts. METHOD: Nine well-trained elite pre-pubertal female gymnasts aged between 9-11 years were participated in this study. Venous blood samples were collected at 08:00h (fasting-before breakfast),09:30h (pre-training),12:30h (post-training) and 14:00h (following recovery) at the last week of transition,preparation and competition training periods. Analysis of the plasma level of leptin,acyl-ghrelin and obestatin concentrations were done using the blood samples. Gymnasts performed their training routines between 09:45-12:30h in 6 day per week during preparation and competition training periods. Repeated measures two way ANOVA and Friedman test was conducted for statistical analysis. RESULTS: Plasma leptin level at fasting and following recovery in competition period were significantly higher than preparation period (p<0.05),furthermore,plasma leptin level at following recovery in transition period was significantly high compared to preparation and competition periods (p<0.05). Moreover,fasting,post-training and following recovery plasma acyl-ghrelin level of transition period was significantly high compared to preparation and competition periods (p<0.05). On the other hand,pre-training plasma obestatin level of transition period was significantly low compared to competition period (p<0.05). CONCLUSION: In this study,variations were observed in the plasma level of leptin,acyl-ghrelin and obestatin hormones related to the gymnastic workouts. It can be speculated that gymnastic workouts in different training periods may affect the growth rate of elite female gymnasts during pre-pubertal period due to the variation of the appetite-regulating hormones.
