】研究结果表明：肩关节屈伸肌群做功值随收缩速度的加快而减小，最大功率峰值则明显增加；体操运动员肩关节在４５°、１３５°时屈伸肌群力矩值与体重的比值和屈、伸比值反映出：一、二级运动员组在４５°时屈肌力量以及在１３５°时伸肌力量需要进一步加强；在力量耐力方面，用功率衰减值来判断体操运动员的耐力优于用功值衰减值进行判断
The results show that the flexion and extension of shoulder flexion and extension muscle work value decreases with the speed of contraction and the peak of maximum power increases obviously. The ratio of flexion and extensor muscle mass to body weight and flexion of gymnastics shoulder joint at 45 ° and 135 ° , The stretching ratio reflects: first and second-class athletes at 45 ° flexor strength and extensor strength at 135 ° need to be further strengthened; in strength and endurance, the use of power attenuation value to determine the endurance of gymnastics is better than the value of work Attenuation value to judge
