不同运动状态的准备活动对动作稳定性和精确性的影响

摘要：目的：探讨静态握笔姿势维持和动态太极拳运动两种不同运动状态的准备活动对动作稳定性和精确性是否存在影响。方法：40名被试随机分成握笔姿势维持组和太极拳运动组，每组被试按照拉丁方顺序依次完成无干预和干预（握笔姿势维持或太极拳运动组）2种条件下动作稳定性和精确性的测试。结果：对动作稳定性测试结果进行双因素混合设计的重复测量方差分析。结果发现，动态准备活动下，太极拳干预组和无干预组不存在显著性差异（F=0.237，P=0.633），不存在性别差异（F=0.048，P=0.829）。在静态准备活动下，握笔干预组和无干预组不存在显著差异（F=0.040，P=0.843），也不存在性别差异(F=2.004,P=0.174)。对动作精确性测试结果进行双因素混合设计的重复测量方差分析，结果发现，动态准备活动下，太极拳干预组与无干预组存在显著性差异（F=4.854，P=0.041），不存在性别差异（F=3.348，P=0.079）。在静态准备活动下，握笔干预组与无干预组不存在显著差异（F=3.420，P=0.081），也不存在性别差异(F=0.167,P=0.688)。结论：太极拳运动改善了动作精确性成绩，对动作稳定性成绩无影响。握笔姿势维持对动作稳定性和精确性成绩均无影响，动作稳定性和精确性成绩均不存在性别差异。

Abstract：Objective: To investigate the effect of the preparation activities of static holding pen posture maintenance and dynamic Taijiquan movement on the stability and accuracy of motion. Methods: 40 participants were randomly pided into holding pen group and shadowboxing group. Each group completed the test of stability and accuracy under two conditions: no intervention and no intervention(holding pen group or shadowboxing group). Results: The results of the motion stability test were analyzed by means of double factor mixing design. It was found that there was no significant difference between the two groups(F = 0.237, P = 0.633) and no gender difference(F = 0.048, P = 0.829). There were no significant differences between the holding intervention group and the dry pre-intervention group(F = 0.040, P = 0.843) or gender differences(F = 2.004, P = 0.174) under static preparedness activities.A double-factor and mixed analysis of measurement variance was carried out. It was found that there were significant differences between the two groups(F = 4.854, P = 0.041) and gender differences(F = 3.348, P = 0.079). There was no significant difference between the holding intervention group and the non-intervention group(F = 3.420, P = 0.081) and no gender difference(F = 0.167, P = 0.688) under static preparedness activities. Conclusion: Taijiquan can improve the performance of movement accuracy and has no effect on the performance of movement stability. There was no effect of holding pen on movement stability and accuracy. There was no gender difference in movement stability and accuracy.
