目的：分析肥胖儿童下肢运动中的异常运动特征。方法：以某市某小学的30名学生为研究对象，将受试者划分为肥胖组和对照组，受试者以一定的角速度完成屈伸运动，各关节进行6次屈伸运动。对所有受试者每个关节最大峰力矩与最大相对峰力矩进行记录及统计。依据Cleveland Clinic法放置反光标记球。实验时要求受试者进行15s静态捕捉，及7个正常步速的步态周期。摄像机采集反光标记球，再利用Vicon Nexus 1.7.1完成自主测量及数据分析，通过Vicon Body Builder求出关节力矩，完成运动学和动力学分析。结果：运动前后肥胖组的身高、体重、BMI均无显著性差异。运动后，肥胖组伸膝绝对肌力、伸膝相对肌力、屈膝相对肌力明显增加，有显著性差异；屈膝绝对肌力、踝背屈绝对肌力、踝趾屈绝对肌力、踝背屈相对肌力、踝趾屈相对肌力非常显著性增加。对照组伸膝绝对肌力及相对肌力均非常显著性下降。肥胖组运动后步幅时间显著下降、步速显著增加，具有统计学意义；对照组运动后步幅时间显著增加，具有统计学意义。运动后肥胖组的髋关节在矢状面活动范围增加，有显著性差异；膝关节在矢状面活动范围降低，有非常显著性差异。肥胖组运动后髋关节的屈力矩增加，有显著性差异。和对照组相比变化值差异有统计学意义。结论：肥胖儿童下肢运动中的异常运动均有所改善。
目的：分析肥胖兒童下肢運動中的異常運動特徵。方法：以某市某小學的30名學生為研究對象，將受試者劃分為肥胖組和對照組，受試者以一定的角速度完成屈伸運動，各關節進行6次屈伸運動。對所有受試者每箇關節最大峰力矩與最大相對峰力矩進行記錄及統計。依據Cleveland Clinic法放置反光標記毬。實驗時要求受試者進行15s靜態捕捉，及7箇正常步速的步態週期。攝像機採集反光標記毬，再利用Vicon Nexus 1.7.1完成自主測量及數據分析，通過Vicon Body Builder求齣關節力矩，完成運動學和動力學分析。結果：運動前後肥胖組的身高、體重、BMI均無顯著性差異。運動後，肥胖組伸膝絕對肌力、伸膝相對肌力、屈膝相對肌力明顯增加，有顯著性差異；屈膝絕對肌力、踝揹屈絕對肌力、踝趾屈絕對肌力、踝揹屈相對肌力、踝趾屈相對肌力非常顯著性增加。對照組伸膝絕對肌力及相對肌力均非常顯著性下降。肥胖組運動後步幅時間顯著下降、步速顯著增加，具有統計學意義；對照組運動後步幅時間顯著增加，具有統計學意義。運動後肥胖組的髖關節在矢狀麵活動範圍增加，有顯著性差異；膝關節在矢狀麵活動範圍降低，有非常顯著性差異。肥胖組運動後髖關節的屈力矩增加，有顯著性差異。和對照組相比變化值差異有統計學意義。結論：肥胖兒童下肢運動中的異常運動均有所改善。

objective: to analyze abnormal movement features of obese children lower limb movement. Methods: a primary school 30 students in a city as the research object, the subjects were divided into obesity group and the control group, the subjects at some angular velocity of the complete flex movement, movement for 6 times each joint flexion and extension.Of all the subjects each joint maximum peak torque and the maximum relative peak torque records and statistics.According to the time's a-clinic place reflective markers ball method.15 s static experiment when participants were asked to capture, and 7 normal pace of the gait cycle.Camera collection and reflective markers, reuse Vicon Nexus 1.7.1 completed independent measurement and data analysis, through the Vicon Body Builder and the joint torque, complete the kinematics and dynamics analysis.Results: before and after exercise height, weight, BMI in obesity group were no significant differences.After exercise, obesity group and the absolute strength, and relative strength, bend your knees relative strength significantly increased, there are significant differences;Knees absolute strength, ankle dorsiflexion absolute strength, ankle foot flexor muscle strength absolutely, ankle dorsiflexion relative strength, ankle foot flexor relative strength very significant increase.The control group and absolute strength and relative strength are very significant decline.Obesity group stride time decreased significantly after exercise, step speed increased significantly, statistically significant;Control group stride time increased significantly after exercise, with statistical significance.Obese after motion of hip joint in sagittal plane range increased, there are significant differences;The knee joint in sagittal plane range is reduced, there is a very significant difference.Obese hip flexion torque increase after exercise, there are significant differences.Value difference compared with the control group was statistically significant.Conclusion: obese children in the lower limb movement, abnormal movement are improved.
