The purpose of this study was to examine the test-retest reliability and the criterion validity of a newly developed chair sit-and-reach (CSR) test as a measure of hamstring flexibility in older adults CSR performance was also compared to sit-and-reach (SR) and back-saver sit-and-reach (BSR) measures of hamstring flexibility. To estimate reliability, 76 men and women (M age = 70.5 years) performed the CSR on 2 different days, 2-5 days apart. In the validity phase of the study, scores of 80 men and women (M age = 74.2 years) were obtained on three field test measures of hamstring flexibility (CSR, SR, and BSR) and on a criterion test (goniometer measurement of a passive straight-leg raise). Results indicate that the CSR has good intraclass test-retest reliability (R = .92 for men; r = .96 for women), and has a moderate-to-good relationship with the criterion measure (r = .76 for men; r = .81 for women). The criterion validity of the CSR for the male and female participants is comparable to that of the SR (r = .74 and r = .71, respectively) and BSR (r = .70 and r = .71, respectively). Results indicate that the CSR test produces reasonably accurate and stable measures of hamstring flexibility. In addition, it appears that the CSR is a safe and socially acceptable alternative to traditional floor sit-and-reach tests as a measure of hamstring flexibility in older adults.
本研究的目的是检验一种新开发的椅子坐位体前屈（CSR）测试的重测信度和效标效度，该测试用于测量老年人的腘绳肌柔韧性。还将CSR测试的表现与腘绳肌柔韧性的坐位体前屈（SR）和省力坐位体前屈（BSR）测试进行了比较。为了评估信度，76名男性和女性（平均年龄 = 70.5岁）在相隔2至5天的2个不同日期进行了CSR测试。在研究的效度阶段，80名男性和女性（平均年龄 = 74.2岁）在腘绳肌柔韧性的三项现场测试（CSR、SR和BSR）以及一项标准测试（被动直腿抬高的角度计测量）中获得了分数。结果表明，CSR具有良好的组内重测信度（男性r = 0.92；女性r = 0.96），并且与标准测量有中度至良好的关系（男性r = 0.76；女性r = 0.81）。CSR对男性和女性参与者的效标效度与SR（分别为r = 0.74和r = 0.71）和BSR（分别为r = 0.70和r = 0.71）相当。结果表明，CSR测试能够产生相当准确和稳定的腘绳肌柔韧性测量结果。此外，作为测量老年人腘绳肌柔韧性的方法，CSR似乎是传统地面坐位体前屈测试的一种安全且社会可接受的替代方法。
