The objectives were 1) to evaluate the hamstring muscle flexibility in children and adolescents; 2) to examine the relative contribution of the spinal curvatures, pelvic tilt and hamstring flexibility on the sit-and-reach (SR) score; and 3) to determine the validity of the sit-and-reach test through both active and passive hip flexion tests. 118 children and adolescents (aged 7-18 years; 60 males and 58 females) were tested for sit-and-reach (SR), passive straight leg raise (PSLR) and active straight leg raise (ASLR). The spinal curvatures and pelvic tilt were assessed during the SR test by means of the Spinal Mouse system. Females showed a statistically greater anterior pelvic tilt, distance reached in the SR test and hip flexion in both PSLR and ASLR tests than males. The pelvic tilt independently explained more than 60% of the variance (distance reached in the SR test) and in conjunction with lumbar flexion explained more than 80% of the variance. In conclusion, the pelvic tilt is the main determinant of SR test in school age children. The SR test can be considered an appropriate and valid test for evaluating pelvic tilt and lumbar flexion in school age children, but not to measure hamstring flexibility.
1）评估儿童和青少年腘绳肌的柔韧性；2）研究脊柱曲度、骨盆倾斜度和腘绳肌柔韧性对坐位体前屈（SR）得分的相对贡献；3）通过主动和被动髋关节屈曲测试确定坐位体前屈测试的有效性。对118名儿童和青少年（年龄7 - 18岁；60名男性和58名女性）进行了坐位体前屈（SR）、被动直腿抬高（PSLR）和主动直腿抬高（ASLR）测试。在SR测试期间，通过脊柱鼠标系统评估脊柱曲度和骨盆倾斜度。女性在统计学上显示出比男性更大的骨盆前倾、SR测试中的伸展距离以及PSLR和ASLR测试中的髋关节屈曲度。骨盆倾斜度独立解释了超过60%的方差（SR测试中的伸展距离），并且与腰椎屈曲一起解释了超过80%的方差。总之，骨盆倾斜度是学龄儿童SR测试的主要决定因素。SR测试可被认为是评估学龄儿童骨盆倾斜度和腰椎屈曲的一种合适且有效的测试，但不适用于测量腘绳肌柔韧性。
