The purpose of this study was to analyze the criterion-related validity and the reliability of the standing long jump test (SLJ) for evaluating the lower-body explosive muscular strength in adults. A total of 410 adults participated in this study. Sociodemographic, anthropometric measurements, laboratory lower-body muscular strength tests, and the field-based SLJ were performed. In validity analysis, stepwise regression analysis showed that maximal horizontal power, sex, percentage of body fat, maximal horizontal force, and lean mass were significantly associated with the SLJ distance (R = 0.78; p < 0.001). Reliability analysis showed significant differences between test-retest in the SLJ test, with an overestimation of the second measurement compared to the first [12.14 ± 14.46 cm, intraclass correlation coefficient (ICC) = 0.94 (0.75-0.97), p < 0.001; Cohen's d = 0.31]. The coefficient of variation (CV) was 7.06% and the minimal detectable change (MDC) was 29 cm. After a learning period, higher reliability values were found [0.45 ± 1.04 cm, ICC = 1.00 (0.99-1.00); p = 0.001; CV = 0.53 %; MDC = 1 cm]. The SLJ test may be a valid tool to assess lower-body explosive muscular strength in the adult population. A learning period may be necessary to provide reliability on the SLJ test.
本研究旨在分析站立跳远测试（SLJ）评估成年人下肢爆发力的效标关联效度和信度。共有 410 名成年人参与了这项研究。进行了社会人口统计学、人体测量学测量、实验室下肢肌肉力量测试以及基于现场的 SLJ 测试。在有效性分析中，逐步回归分析显示，最大水平功率、性别、体脂百分比、最大水平力和瘦体重与 SLJ 距离显著相关（R=0.78；p<0.001）。可靠性分析显示，SLJ 测试的两次测试之间存在显著差异，第二次测量值高于第一次测量值[12.14±14.46cm，组内相关系数（ICC）=0.94（0.75-0.97），p<0.001；Cohen's d=0.31]。变异系数（CV）为 7.06%，最小可检测变化（MDC）为 29cm。经过学习阶段后，发现可靠性值更高[0.45±1.04cm，ICC=1.00（0.99-1.00）；p=0.001；CV=0.53%；MDC=1cm]。SLJ 测试可能是评估成年人下肢爆发力的有效工具。可能需要一个学习阶段来提供 SLJ 测试的可靠性。
