Abstract


Myostatin is one of the latest discovered cytokines, which regulates skeletal muscle growth negatively. The plan of research is so that two protocols of football-specific training and resistance-plyometric training on the serum level of myostatin GASP-1 and IGF-I are compared after young football players’ 8 weeks training. 30 youth soccer players with a range of 14 to 17 years of age were divided randomly in three groups, SSG (n=8), resistance-plyometric (n=11) and control (n=11). Height, weight, BMI and VO2max of the subjects were measured. The next day, blood samples from the anterior brachial vein of subjects were taken. The experimental groups participated in their exercise program (8 week, 2 sessions per week plus three current sessions). All variables were measured again after 8 weeks. In order to compare data within groups' Dependent t-test was used and for comparison between groups dependent t-test was used by SPSS 17. The result of the research showed that eight weeks of resistance-plyometric training brought about a significant decrease of myostatin and a significant increase of GASP-1 and IGF-I. More studies of the interchange and relationship of these variables with growth, biochemical mediators in plasma can show us a clearer image of the role of these changes.
