BACKGROUND
Clinicians often use physical performance tests (PPT) to measure performance measures in sports since they are easy to administer, portable, and cost-efficient. However, PPT often lack good or known psychometric properties. Perhaps, the 30-second chair-stand test (30CST) would be a good functional test in athletic populations as it has been shown to demonstrate good psychometric properties in older adults.
HYPOTHESIS/PURPOSE: The purpose of this study was to determine normative values for and concurrent, convergent and discriminative validity of 30CST for healthy young adults aged 19-35 years.
STUDY DESIGN
Cross-sectional.
METHODS
Eighty-one participants completed this study. All participants performed two trials of 30CST, 5-times sit-to-stand (5xSTS), and lateral step-up test (LSUT). Investigators used the International Physical Activity Questionnaire Leisure Domain (LD-IPAQ) to divide participants into insufficiently or sufficiently active groups based on the weekly metabolic equivalent of task per the Physical Activity Guidelines for Americans.
RESULTS
Participants (Mean + SD age, 25.1 ± 3.4 years; body height, 1.71 ± 0.09 m; body mass, 72.6 ± 16.1 kg; females 47) performed an average of 33.0±5.4 30CST repetitions. The 30CST performance was negatively associated with 5xSTS (=-0.79 =0.01) and positively associated with LSUT performances (=0.51, =0.01) when using Pearson correlations. In addition, the sufficiently active group performed significantly greater 30CST repetitions than the insufficiently active group (mean difference = 2.5; =0.04).
CONCLUSIONS
In addition to finding a reference value for 30CST performance in young adults, investigators found that the 30CST displayed concurrent and convergent validity in assessing functional lower extremity (LE) muscle strength and discriminated between those with sufficient and insufficient physical activity levels. Training and rehabilitation professionals could use the 30CST for testing functional LE muscle strength for athletes in pre-season or during rehabilitation. Future investigators should perform studies to determine if 30CST predicts sport performance.

背景
临床医生经常使用身体机能测试（PPT）来测量运动中的机能指标，因为这些测试易于实施、便于携带且成本效益高。然而，PPT往往缺乏良好的或已知的心理测量学特性。或许，30秒坐立试验（30CST）对运动员群体来说会是一项不错的功能测试，因为它已被证明在老年人中具有良好的心理测量学特性。
假设/目的：本研究的目的是确定19至35岁健康年轻成年人30CST的常模值以及同时效度、收敛效度和区分效度。
研究设计
横断面研究。
方法
81名参与者完成了本研究。所有参与者都进行了两次30CST、5次坐立试验（5xSTS）和侧步上台阶试验（LSUT）。研究人员使用国际体力活动问卷休闲领域（LD - IPAQ），根据《美国体力活动指南》中每周的任务代谢当量，将参与者分为活动不足或活动充足组。
结果
参与者（平均年龄 + 标准差，25.1 ± 3.4岁；身高，1.71 ± 0.09米；体重，72.6 ± 16.1千克；女性47名）30CST平均重复33.0 ± 5.4次。使用Pearson相关性分析时，30CST表现与5xSTS呈负相关（r = -0.79，P = 0.01），与LSUT表现呈正相关（r = 0.51，P = 0.01）。此外，活动充足组的30CST重复次数显著多于活动不足组（平均差异 = 2.5；P = 0.04）。
结论
除了得出年轻成年人30CST表现的参考值外，研究人员还发现30CST在评估下肢（LE）功能肌肉力量方面显示出同时效度和收敛效度，并且能够区分身体活动水平充足和不足的人群。训练和康复专业人员可以在赛季前或康复期间使用30CST来测试运动员的下肢功能肌肉力量。未来的研究人员应进行研究，以确定30CST是否能预测运动表现。
