Abstract:
75 SUMMARY: In preseason and after a nine-week training term, seventeen Turkish Second Soccer League players' body composition, aerobic power and using Cybex 2-340 isokinetic dynamometer knee flexor-extensor muscle peak torques (pt.), hamsrinq/ quadriceps (H/Q) pt. ratios and muscle endurance were measured and the differences in preseason and season were determined. The body fat ratio of the players was %10.84±1.44 in preseason and %10.67±1.14 in season. No significant difference was determined. The indirect maxVOo value was 45.83İ8.99 ml/kg/min in preseason and 54.36+9.6 uil/ kg/mi n in season. The increase was significant; at p<^0. 01 level. ; A.t the end of a nine-week training term, increase in knee flexor and extensor muscle peak torque was determined. Especially in knee flexor increase was more evident. After training term, in 300 °/sec. anguler speed, nondominant leg knee extensor pt. at p<0.05 level, in 60 °/sec. and 180 °/sec. dominant leg knee flexor pt. respectively at p<(0.05, p^O.05 level, in 180 °/sec. and 300 °/sec. nondominant leg knee flexor pc. respectively at p<^0.01, p<(0.01 level showed significant Increase.76 In 60 °/ sec. dominant leg H/Q pt. ratio was %60.71+8.26 in preseason and %64. 76 ±10.13 in season.: The increase was significant at:p<(0.05 level. In other anguler speeds, although H/Q pt. ratios in season statistically were nor significant, they war a higher considering preseason. No significant difference was found between dominant leg and nondominant leg endurance ratios in any measurement. No significant difference was determined in both legs endurance racio by training. Consequently, after a nine-week soccer training in which strength exercises took place, 'although it was more evident in flexor, knee flexor and extensor pt. values of the sportsmen increased. H/Q pt. ratios changed in the way cf increase. These findings support the idea that soccer training improves knee f lexer muscle strength. No increase in.endurance ratio in season can be an indicator to show that exercises done during training period are not sufficient to improve muscle endurance. Giving enough importance to strength exercises in soccer in preseason will especially contribute to knee flexor muscle strength to improve and bilateral, agonist-antagonist muscle strength to save its balance.
