为了解肘关节屈、伸肌群在不同收缩方式、不同运动速度、不同关节角度时力矩变化情况。为运动医学、临床医学、康复医学的实践提供参考，用BIODEX等速测力及康复系统，测定了北京体育大学体育生物科学系9名男生肘关节屈、伸肌群静力和等速向心、等速离心不同运动速度的肌力。结果为：肘关节屈、伸肌群最大力矩与肌肉收缩方式的关系符合一般规律，即离心收缩大于静力收缩，静力收缩又大于向心收缩。肘关节屈、伸肌群最大力矩，在收缩速度为60°～120°／s范围内．无明显差异，可选为慢速测试速度。如测定快速肌力，速度至少提高到180°／s以上。肘关节屈／伸肌群力矩比率均值＞1，即屈肌肌力大手伸肌肌力，但个体差异较大。并根据肘关节屈、伸肌群力矩、最大力矩与关节角度的关系，提出进行直立位屈肘力量练习时，可取肩关节屈曲10°～20°用的位置；进行伸肘肌群力量练习时，可采取直立位头后上举的抗阻练习。
In order to understand the elbow flexion and extension groups in different ways of contraction, different speed, different joint angle torque changes. This paper provides a reference for the practice of sports medicine, clinical medicine and rehabilitation medicine. By using the BIODEX constant force test and rehabilitation system, we measured the flexion and extension of flexors and extensors of 9 male students in Department of Physical Education of Beijing Sport University , Isokinetic centrifugal force different muscle speed. The results are: elbow flexion and extension group maximum torque and muscle contraction mode in line with the general law that the centrifugal contraction is greater than the static contraction, static contraction is greater than the centripetal contraction. Elbow flexion, extensor group maximum torque, in the contraction rate of 60 ° ~ 120 ° / s range. No significant difference, optional for slow test speed. If measured fast muscle strength, the speed increased to at least 180 ° / s above. Elbow flexor / extensor group moment ratio average> 1, that is, muscle flexor muscle strength, but individual differences. According to the relationship between elbow flexion, extensor group flexion torque and maximal moment and joint angle, it is proposed that flexion of the shoulder joint can be flexed by 10 ° ~ 20 ° when performing elbow flexion strength training. For elbow muscle strength training , You can take the vertical head after the resistance exercises on the move.
