Effect of 8weeks of Power Training Program on Leg Strength, Anaerobic Power and Blood Lactate Concentration of Elite Soccer Players

The purpose of this study was to investigate the effect of 8weeks of power training program on leg strength, anaerobic power and blood lactate concentration in elite soccer players. Power training program was conducted 60mins/day, 3days/week for 8weeks. The subjects of this study selected 24 elite soccer players(CG=12, PG=12) and the results were as follows. In the hip strength, the interaction effect was significant in the abduction(p.05), adduction(p.01) and flexion(p.05) on the left side and abduction (p.01), adduction(p.05), and extension(p.01) on the right side. In the isokinetic knee muscular function, the interaction effect was significant in left knee flexor(p.05) and extensor muscle(p.01) function and in right knee flexor(p.01) muscle function. Also, interaction effect of anaerobic power per body weight was significant at 1st(p.05) and 3nd phases(p.05), and interaction effect of lactate recovery period was significant at 30 minutes(p.05). From the results, it was suggested that 8weeks of specific power training has a crucial role in improvement of anaerobic capacity and improved ability to recovery capacity from anaerobic exercise in elite soccer players.
