Abstract

Objective

The purpose of this study was to determine the extent to which the mean peak moment (MPM) of knee flexors and extensors could predict performance in a group of healthy individuals.

Methods

Eighty-four healthy individuals—32 men and 52 women (mean age, 22.1 ± 3 years; range, 18-35 years)—participated in this study. Isokinetic unilateral concentric knee flexor and extensor MPM was assessed isokinetically at angular velocities of 60°/s and 180°/s. Functional performance was assessed using the single hop of distance (SHD).

Results

Positive moderate to good statistically significant correlations (r = .636 to r = .673) were found between knee flexor and extensor MPM at 60°/s and 180°/s for the SHD test. Knee flexor and extensor MPMs are strong predictors for the SHD test at 60°/s and 180°/s (R² = .40 to R² = .45).

Conclusion

Knee flexor and extensor strength was substantially correlated with SHD.

健康青年参与者等速膝关节力量特征与单腿跳跃表现之间的关系

目的本研究的目的是确定膝关节屈伸肌的平均峰值矩(MPM)在多大程度上可以预测一组健康个体的运动表现。方法84例健康个体，男性32例，女性52例(平均年龄22.1±3岁;年龄范围:18-35岁)。在角速度为60°/s和180°/s时，等速评估单侧同心圆膝关节屈伸肌MPM。使用单跳距离(SHD)评估功能性能。结果在60°/s和180°/s的SHD测试中，膝关节屈肌和伸肌MPM之间存在中度至良好的统计学显著正相关(r = 0.636至0.673)。膝关节屈肌和伸肌mpm是60°/s和180°/s时SHD测试的强预测因子(R2 = 0.40至R2 = 0.45)。结论膝关节屈伸肌力与SHD有显著相关性。
