目的 比较10~11岁长期足球锻炼男童和一般男童下肢肌力的差异。方法 选取身高、体重相匹配,具有2年足球锻炼经验(足球锻炼组)和一般(对照组)男童各30名,采用德国IsoMed 2000等速测试仪,对两组受试者进行髋、膝和踝关节屈伸模式的测试。结果 1)足球锻炼组的髋关节屈(t=1.314)、伸(t=1.972)和膝关节屈(t=1.897)、踝关节伸(t=1.128)峰力矩大于对照组但无统计学意义(P均>0.05);2)足球锻炼组的膝关节伸(t=-5.812)和踝关节屈(t=3.064)峰力矩显著大于对照组(P均<0.01)。结论 长期的足球锻炼显著改善了学龄男童膝关节伸肌、踝关节屈肌的力量,虽然对髋关节屈伸肌力有所改善但不显著。

Objective To compare the difference of muscle strength of lower limbs between 10~11 years old boys who take football exercise in long time and who don't take football exercise. Methods A total of 60 boys who have similar height and weight were divided into two equal groups,and one group who had two years football exercise as football exercise group and the other group without football exercise as control group,the tests on flexion and extension model of hip joint,knee joint and ankle joint of two groups were done by using Germen IsoMed 2000 isokinetic dynamometer. Results 1)The peak torque of football exercise group which get hip joint flexion(t=1.314),extension(t=1.972),knee joint flexion(t=1.897),ankle joint extension(t=1.128),were larger than the control group,but not significant (P>0.05).2)The peak torque of football exercise group who get knee joint extension (t=-5.812),and ankle joint flexion (t=3.064),were significantly larger than control group (P<0.01). Conclusion To boys,long football exercise can significantly improve the strength of knee joint extensor,ankle joint flexor and slightly improve the strength of hip joint flexor and extensor.
