摘要

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。

Association Between Isokinetic Knee Strength Characteristics and Single-Leg Hop Performance In Healthy Young Participants

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).
