Grip strength, a biomarker, can be measured at any age; however, its values vary daily for each individual, which impacts the assessment. Absolute test-retest reliability (i.e., minimal difference, MD) is commonly defined as the variation in absolute values of measurements taken by a single person or instrument on the same item under identical conditions. Nevertheless, the potential moderators of absolute repeatability in grip strength measurements have not yet been fully elucidated. We conducted a systematic review with meta-analysis to examine the influence of potential moderating factors on the absolute test-retest repeatability of grip strength measurements in healthy populations. PubMed, Scopus, and SPORTDiscus databases were searched up to January 2025 following the PRISMA guidelines, and 48 studies were included in this review. Age, test-retest interval, and device were used as potential moderating factors; however, sex and sports experience were excluded due to the limited number of published articles. We found considerable variation among studies reporting MD and percentage of MD to measured value (%MD) across each age group. The mean MD (%MD) values were 1.9 kg (25.4%) in young children (<7 years old), 2.5 kg (13.8%) in children (7-10 years old), 4.2 kg (17.1%) in adolescents (10-18 years old), 4.0 kg (11.6%) in young adults (18-35 years old), and 4.7 kg (16.7%) in older adults (>60 years old). Neither age [effect size [ES]: 0.015 (95% confidence interval [CI]: -0.004, 0.035; p = 0.113) for MD and ES: -0.025 (95% CI: -0.089, 0.039; p = 0.439) for %MD], test-retest interval [ES: 0.006 (95% CI: -0.002, 0.013; p = 0.143) for MD and ES: 0.022 (95% CI: -0.001, 0.046; p = 0.065) for %MD] nor handgrip device (p = 0.752 for MD and p = 0.334 for %MD) served as significant moderators of MD and %MD reliability. Due to the limited number of studies, sex and sports experience were excluded from the analysis; as a result, their impacts remain unknown.
握力作为一种生物标志物，可在任何年龄进行测量；然而，每个人的握力值每天都会有所变化，这对评估产生影响。绝对重测信度（即最小差异，MD）通常定义为同一个人或仪器在相同条件下对同一项目进行测量的绝对值变化。然而，握力测量中绝对可重复性的潜在调节因素尚未完全阐明。我们进行了一项系统评价和荟萃分析，以研究潜在调节因素对健康人群握力测量绝对重测可重复性的影响。按照PRISMA指南，检索了截至2025年1月的PubMed、Scopus和SPORTDiscus数据库，本评价纳入了48项研究。年龄、重测间隔和测量设备被用作潜在调节因素；然而，由于已发表文章数量有限，性别和运动经历被排除在外。我们发现，各年龄组报告的MD和MD与测量值百分比（%MD）之间存在相当大的差异。幼儿（<7岁）的平均MD（%MD）值为1.9千克（25.4%），儿童（7 - 10岁）为2.5千克（13.8%），青少年（10 - 18岁）为4.2千克（17.1%），年轻人（≥18岁）为4.0千克（11.6%），老年人（>60岁）为4.7千克（16.7%）。年龄[MD的效应量[ES]：0.015（95%置信区间[CI]：-0.004，0.035；p = 0.113），%MD的ES：-0.025（95%CI：-0.089，0.039；p = 0.439）]、重测间隔[MD的ES：0.006（95%CI：-0.002，0.013；p = 0.143），%MD的ES：0.022（95%CI：-0.001，0.046；p = 0.065）]和握力测量设备（MD的p = 0.752，%MD的p = 0.334）均未作为MD和%MD可靠性的显著调节因素。由于研究数量有限，性别和运动经历被排除在分析之外；因此，它们的影响仍然未知。
