To examine the test-retest reliability of student-administered (SA) health-related fitness tests in school settings and to compare indices of reliability with those taken by trained research-assistants.
Participants (n = 86; age: 13.43 [0.33] y) were divided into 2 groups, SA (n = 45, girls = 26) or research-assistant administered (RA; n = 41, girls = 21). The SA group had their measures taken by 8 students (age: 15.59 [0.56] y, girls = 4), and the RA group had their measures taken by 8 research-assistants (age: 21.21 [1.38], girls = 5). Tests were administered twice by both groups, 1 week apart. Tests included body mass index, handgrip strength, standing broad jump, isometric plank hold, 90° push-up, 4 × 10-m shuttle run, back-saver sit and reach, and blood pressure.
Intraclass correlation coefficients for SA (≥.797) and RA (≥.866) groups were high, and the observed systematic error (Bland-Altman plot) between test 1 and test 2 was close to 0 for all tests. The coefficient of variation was less than 10% for all tests in the SA group, aside from the 90° push-up (24.3%). The SA group had a marginally lower combined mean coefficient of variation across all tests (6.5%) in comparison with the RA group (6.8%).
This study demonstrates that, following familiarization training, SA health-related fitness tests in school-based physical education programs can be considered reliable.
检验学校环境中学生自主管理（SA）健康相关体能测试的重测信度，并将信度指数与经过培训的研究助理所测的指数进行比较。
将 86 名参与者（年龄：13.43 [0.33]岁）分为两组，SA 组（n = 45，女生 26 人）或研究助理管理（RA）组（n = 41，女生 21 人）。SA 组由 8 名学生（年龄：15.59 [0.56]岁，女生 4 人）进行测量，RA 组由 8 名研究助理（年龄：21.21 [1.38]岁，女生 5 人）进行测量。两组均在 1 周内进行两次测试。测试包括体重指数、握力、立定跳远、等长平板支撑、90°俯卧撑、4×10 米折返跑、背力坐伸和血压。
SA（≥.797）和 RA（≥.866）组的组内相关系数均较高，且两次测试之间的观察系统误差（Bland-Altman 图）接近 0。除 90°俯卧撑（24.3%）外，SA 组所有测试的变异系数均小于 10%。与 RA 组（6.8%）相比，SA 组所有测试的综合平均变异系数（6.5%）略低。
本研究表明，在经过熟悉化训练后，学校体育教育项目中 SA 健康相关体能测试可以被认为是可靠的。
