跆拳道训练对学龄儿童静态平衡能力的影响

研究目的：通过对比正常学龄儿童与跆拳道训练的学龄儿童平衡能力，以探索跆拳道训练对学龄儿童静态平衡能力的影响。研究方法：选取参加跆拳道训练的学龄儿童10名作为实验组，匹配10名无跆拳道训练、武术及其他专项练习的学龄儿童作为对照组。采用win-pod平衡功能检测系统对受试者进行单足和双足平衡能力测试。研究结果：双足睁眼或闭眼测试时，有跆拳道训练的学龄儿童与无跆拳道训练、武术及其他静力练习的学龄儿童相比静态平衡能力差异有统计学意义（P＜0.05）；在睁眼左足测试时，实验组与对照组差异有统计学意义（P＜0.05）主要体现在重心动摇轨迹长、重心平均动摇速度、Y轴动摇速度这些指标上；而在睁眼右足测试时，实验组与对照组各项指标中除了Y轴平均摆幅这项指标，其他指标在两组之间差异都有统计学意义（P＜0.05）；闭眼单足测试时，从左右足依次来看，实验组与对照组分别在Y轴动摇速度和Y轴平均摆幅差异有统计学意义（P＜0.05）。研究结论：跆拳道训练能够有效增强学龄儿童在双足和右足站立静态站立的静态平衡能力，提高站立的姿势稳定性。

Effect of Taekwondo Training on the Static Balance Ability of School Children

Objective: Balance ability was compared between the normal school-age children and the school children with taekwondo training in order to explore the effect of taekwondo training on the static balance ability of school children. Method: Ten school children with taekwondo training were selected as the subjects of the experimental group, and 10 other school children without the training of taekwondo, martial arts and other special practice as the subjects of the control group. Single or double feet balance ability were tested with Win-pod Balance Function Test System. Result: There was statistical significance of the static balance difference between the two groups during double-feet standing test with eyes open or closed(P< 0.05); The difference between the two groups have statistical significance during the left-foot standing test with eyes open (P< 0.05). This can be seen in the indicators of the postural sway path length, the gravity average shake speed and the Y axis sway velocity. While in the test of right-foot standing with eyes open, the difference of the indexes of the two groups have statistical significance except Y axis average swing (P< 0.05). During the single-foot standing with eyes closed, the difference of Y axis shaking speed and Y axis average swing has statistical significance (P< 0.05). Conclusion: Taekwondo training may effectively improve the static balance ability of school children in the posture of double-feet standing and right-foot standing and improve posture stability in standing.
