测量下半身力量对于评估老年人的功能表现至关重要。本研究的目的是评估重测信度和标准相关和结构效度的30年代椅子站作为衡量下半身力量的成年人在GO年以上。76名社区居住的老年人（M年龄= 70.5岁）自愿参加这项研究，其中包括进行两个30-s椅子站立测试和两个最大腿部压力测试，每个测试在分开的2-5天进行。重测组内相关系数为0.84（男性）和0.92（女性），采用适用于单次试验的单因素方差分析程序，以及从第1天测试到第2天的评分无显著变化，表明30秒椅子站立具有良好的稳定性可靠性。对于男性和女性来说，椅子站立表现和最大重量调整腿部推举表现之间的适度高相关性（分别为r = .78和.71）支持椅子站立作为下半身力量测量的标准相关有效性。结构（或判别）的椅子站的有效性证明了测试的能力，以检测不同年龄和体力活动水平组之间的差异。正如预期的那样，椅子站立的表现在几十年来在各个年龄组中显着下降-从60年代到70年代再到80年代（p < .01），并且低活动参与者的表现显着低于高活动参与者（p < .0001）。得出的结论是，30年代椅子的立场提供了一个合理的可靠和有效的指标较低的身体力量在一般活跃，社区居住的老年人。
Measuring lower body strength is critical in evaluating the functional performance of older adults. The purpose of this study was to assess the test-retest reliability and the criterion-related and construct validity of a 30-s chair stand as a measure of lower body strength in adults over the age of GO years. Seventy-six community-dwelling older adults (M age = 70.5 years) volunteered to participate in the study, which involved performing two 30-s chair-stand tests and two maximum leg-press tests, each conducted on separate days 2-5 days apart. Test-retest intraclass correlations of .84 for men and .92 for women, utilizing one-way analysis of variance procedures appropriate for a single trial, together with a nonsignificant change in scores from Day 1 testing to Day 2, indicate that the 30-s chair stand has good stability reliability. A moderately high correlation between chair-stand performance and maximum weight-adjusted leg-press performance for both men and women (r = .78 and .71, respectively) supports the criterion-related validity of the chair stand as a measure of lower body strength. Construct (or discriminant) validity of the chair stand was demonstrated by the test's ability to detect differences between various age and physical activity level groups. As expected, chair-stand performance decreased significantly across age groups in decades-from the 60s to the 70s to the 80s (p < .01) and was significantly lower for low-active participants than for high-active participants (p < .0001). It was concluded that the 30-s chair stand provides a reasonably reliable and valid indicator of lower body strength in generally active, community-dwelling older adults.
