性别、年龄和身体形态对青少年核心稳定性的影响

Effects of gender, age and figure on teenagers' core stability

为了进一步了解性别、年龄和身体形态与核心稳定性之间的关系,选择17和13岁普通健康青少年男女受试者80名,通过Mc Gill核心稳定性测试和身高、体重、体脂百分比等身体形态测试,对比不同性别和不同年龄受试者核心稳定性测试数据,分析不同身体形态学指标与核心稳定性测试数据的相关性。结果显示,不同年龄和性别青少年受试者核心稳定性系列测试结果均无显著性差异。青少年身高与核心稳定性系列测试结果不具有显著相关关系;体重仅与核心稳定性系列测试中,腰部伸展测试结果呈中度负相关;BMI与核心稳定性系列测试中,腰部伸展测试和右侧桥测试结果均呈中度负相关;体脂百分比与核心稳定性系列测试中,左、右侧桥测试结果有非常显著相关关系,呈中度负相关。所以,对于青少年个体来说,性别、年龄和身高对核心稳定性没有影响,而体重、BMI和体脂百分比与核心稳定性有一定关系。研究推测核心稳定性测试方法的选择与测试对象的不同对研究结果有着重要影响。

In order to further understand the relations between gender, age, figure and core stability, the authors selected 80male and female teenage testees age 17 or 13, by means of McGill core stability test and figure tests such as height, weightand body fat percentage tests, compared the core stability test data of the testees of different genders and ages, analyzed thecorrelations between different figure indexes and core stability test data, and revealed the following findings： there were nosignificant differences in the core stability series test results of the teenage testees of different genders and ages; there wasno significant correlation between teenagers’ height and core stability series test results; weight showed a medium negativecorrelation only with the result of waist stretching test in core stability series tests; BMI showed a medium negative correlationwith the results of waist stretching test and right lateral bridge test in core stability series tests; body fat percentageshowed a very significant medium negative correlation with the results of left and right lateral bridge tests in core stabilityseries tests. Therefore, as for teenage individuals, gender, age and height have no effect on core stability, yet weigh, BMIand body fat percentage have a certain relation with core stability. The authors figured that the selection of core stabilitytest method and the difference of test objects had an important effect on research results.
