摘要
探讨优秀男子跳远运动员下肢关节肌力特征,并比较健将组与一级组的差异。采用德国产IsoMed2000等速测试仪,对跳远健将组(7人)、一级组(8人)进行左、右髋、膝和踝关节60°/S(5次)和240°/S(25次)屈、伸模式的测试。结果显示:1)健将的优势在踝关节屈的绝对力量和髋(伸)、膝(伸)、踝(屈)的爆发力上;2)健将组与一级组下肢关节屈、伸肌群比值范围无显著差异,髋关节在0.63-0.82之间、膝关节在0.56-0.64之间、踝关节在2.69-5.53之间;3)健将组与一级组的膝、踝关节伸肌群耐力有待加强。
The paper is to explore the muscle strength characteristics of male elite long jumpers＇lower extremity and to compare the differences between the master- group and first -grade group. Isokinetic dynamometer （ IsoMed 2000 from Germany） is adopted to measure the muscle strength for the subjects＇ （ seven master group and eight first - grade athletes） hip , knee and ankle joint at the flexion and extension mode. 5 repeated maximum isokinetic contractions with an angular velocity of 60°/s at the angular velocity of 240°/s are measured 25 times. Results： （1） The master group show their advantages in their ankle flexors＂ absolute force and explosive power in the hip , knee extensors and ankle flexors ; （2） The specific value range of the two groups shoe no significant differences in their lower limb joint flexor and extensor, with the hip range ratio being 0. 63 - 0.82, knee, 0. 56 - 0.64, ankle, 2.69 - 5.53 ; （3） All the subjects＇knee and ankle joint muscle endurance should be strengthened.
