摘要

【目的】本研究旨在通过比较优势腿和非优势腿的下肢肌肉力量、跳跃距离和方向速度变化来确定健康男性在参加非接触性损伤运动时的下肢不对称性。[参与者和方法]研究参与者包括16名健康男性,他们在测量时至少参加了四年的特定运动。我们测量了五个肌肉群的最大等长力量,并进行了六次性能测试。下肢对称指数计算公式为:(非优势腿/优势腿)× 100。【结果】髋关节屈肌、髋关节外展肌、膝关节屈肌和膝关节伸肌的力量水平存在显著差异。除髋屈肌外,下肢所有肌肉的对称指数在91%到98%之间。在性能测试中,在交叉跳测试和90°方向变化测试中发现了显著差异。在所有的性能测试中,下肢对称指数在96%到103%之间。[结论]我们建议根据所采用的测试类型,在评估是否恢复运动时考虑腿部优势。

Lower-limb asymmetry in healthy male athletes.

Lower-limb asymmetry in healthy male athletes.

[Purpose] This study aimed to determine lower extremity asymmetry in healthy males when participating in sports where non-contact injuries are common by comparing lower extremity muscle strength, jumping distance, and change of direction speed between the dominant and non-dominant legs. [Participants and Methods] Study participants included 16 healthy males who had been playing a specific sport for at least four years at the time of measurement. We measured the maximal isometric strength of five muscle groups and conducted six performance tests. The lower-limb symmetry index was calculated as follows: (non-dominant leg/dominant leg) × 100. [Results] Significant differences were found in the strength levels of hip flexors, hip abductors, knee flexors, and knee extensor muscles. The lower-limb symmetry index for all muscles, except for the hip flexors, ranged from 91% to 98%. In the performance tests, significant differences were found in the crossover hop test and the 90° change of direction test. The lower-limb symmetry index ranged from 96% to 103% in all the performance tests. [Conclusion] We suggest that leg dominance be considered in assessments for determining return to sports based on the type of tests employed.
