A cross-sectional analysis of sagittal knee laxity and isokinetic muscle strength in soccer players.

摘要: In this cross-sectional study, sagittal knee laxity and isokinetic strength of extensor flexor muscle groups were measured differences related to leg dominance evaluated. A total 44 healthy male soccer players (who had trained regularly at least for the last five years) sedentary people as their control counterparts involved in study. All participants tested using a KT-1000 arthrometer laxity. Isokinetic concentric peak torque hamstring/quadriceps (H/Q) ratio also 60, 180, 300 degrees/s through Cybex 2 - 340 dynamometer. Posterior non-dominant side was significantly higher than dominant (p < 0.005) while there no significant anterior anteroposterior (total AP) both groups. Soccer lower AP values controls 0.0001) difference between posterior sides. Dominant extremity demonstrated H/Q 180 degrees /s 0.05).
