【摘要】 运用文献资料法和实验法对当前存在的两种坐位体前屈——普通坐位体前屈和改进型坐位体前屈的效度进行了分析。结果显示;与普通坐位体前屈相比,改进型坐位体前屈的测量结果剔除了下肢长的影响,减少了上肢长的影响,虽然在一定程度上提高了测量的效度,但并没有完全克服身体形态因素的影响。运用指数法表述改进型坐位体前屈的测量结果能够提高测量效度。更多还原

【Abstract】 With the methods of literature and experiment,the author analyzes two kinds measuring techniques of Sit-and-reach-ordinary Sit-and-reach and advanced version Sit-and-reach.The result is that the advanced version Sit-and-reach has completely rejected the influence which the lower limb length creates,reduced the influence of the upper limb length,elevated the validity in a certain extent,but has not reduced the influence of the body shape;taking the quotient for the flexible index could enhance the survey of the validity.更多还原
