Abstract

The aim of the present study was to investigate the effect of 12 weeks of strength-power training with different loads on muscular and performing functions in elite soccer players. 36 subjects from 4 universities were randomly divided into 3 equal groups: group 1 (strength-power training with 60-70% of 1RM), group 2 (strength-power training with 70-80% of 1RM) and group 3 (strength - power training with 80-90% of 1RM). Strength-power training program included 6 movements which were performed for 12 weeks (3 sessions per week) for all groups. Results showed that heavy load significantly increased muscular strength of lower body compared with the light load. The heavy and intermediate loads significantly increased anaerobic power of lower body compared with the light load. The heavy load significantly decreased the time of 20 and 30 meter run and Hoff test compared with the light and intermediate loads. No significant differences were observed in other loads. Also, there were no significant differences in the 10 meter sprint and explosive power. It is suggested that soccer players should use strength- power training with the load of 80-90% of 1RM to improve their muscular and performing functions.
