摘要：

背景：以往对小学生下肢力量发育的评估，主要局限于立定跳远和纵跳摸高等身体素质的测量，缺乏对其肌肉功能的定量性研究。
目的：通过小学生膝关节屈伸肌力发展现状进行测试分析，正确认识小学生关节肌肉力量发育特征。
方法：运用“Kinitech”等速肌力测试系统对随机抽取石家庄市年龄为9~12岁的54名健康小学生(男25例、女29例)膝关节屈伸肌群进行60，120，240 (°)/s三种速度测试。
结果与结论：小学生膝关节屈、伸肌群峰力矩均呈现随测试速度增加而下降的现象；男、女生左侧屈肌群在60，120 (°)/s时及右侧屈肌群在60 (°)/s时，峰力矩低于伸肌群峰力矩(P < 0.01或P < 0.05)。同一测试速度下，在测试速度为240 (°)/s时，男生左侧屈、伸肌群及右侧屈肌群峰力矩明显高于女生(P < 0.01或P < 0.05)。

Abstract:

BACKGROUND: Previous evaluation for lower limb strength in primary students are limited for physical quality measurement, such as standing long jump or jump touching, which lack of quantitative studies. 
OBJECTIVE: To learn the characteristic of development in muscle strength in primary students using isokinetic testing system.
METHODS: The flexion and extension strength of knee joints in 54 healthy primary students aged 9-12 (25 boys and 29 girls) were measured by using Kinitech Isokinetic testing system with 3 angular velocities: 60 (°)/s, 120 (°)/s and 240 (°)/s.
RESULTS AND CONCLUSION: The peak torque (PT) of primary students was decreased with angular velocities increasing; The PT value of left side at speed of 60 (°)/s and 120 (°)/s, and right side at speed of speed of 60(°)/s was lower than that of the extensors in both genders (P < 0.01 or P < 0.05). At the same speed, the PT value of flexor and extensor in left side and flexor in the right side of boys were obviously higher than that of girls at 240 (°)/s (P < 0.01 or P < 0.05).
