This study aimed to explore the inter-session reliability of the measures obtained from 2 trunk extension (Biering-Sorensen and Dynamic Extensor Endurance (DEE) tests) and 3 trunk flexion (Ito, Side Bridge and Bench Trunk Curl-Up (BTC) tests) endurance field-based tests in adolescents. A total of 208 (males, n = 100; females, n = 108) adolescents performed all the field-based tests on 2 separate testing sessions, 7-days apart. The inter-session reliability scores were explored through relative reliability, inter-session differences and precision of measurements. Most of the trunk endurance measures demonstrated acceptable relative reliability (the intraclass correlation coefficients (ICC) ranged from 0.75 to 0.94). However, significant inter-session differences were identified for measures from the DEE and BTC tests. Likewise, the precision of the measurement of each field-based test was poor (the the standard error of measurement expressed as a percentage of the mean score (CV) ranged from 11.3 to 24.4%) with the minimal detectable change (MDC) revealing that changes higher than 42% for trunk extension endurance tests and 31.4% for trunk flexion endurance tests after an intervention are required to indicate a significant change above measurement error. Therefore, the findings from this study indicate that only the BTC test demonstrates acceptable inter-session reliability (ICC > 0.9, CV ~ 10%, MDC ~ 30%) to monitor the changes in trunk endurance scores that may be expected in adolescents after performing an intervention programme.
本研究旨在探讨 2 项躯干伸展（比耶林-索伦森和动态伸展耐力测试）和 3 项躯干弯曲（伊藤、侧桥和仰卧起坐测试）耐力场测在青少年中的测试间可靠性。共有 208 名（男性，n=100；女性，n=108）青少年在 2 个不同的测试日（间隔 7 天）上完成了所有的场测。通过相对可靠性、测试间差异和测量精度来探索测试间可靠性评分。大多数躯干耐力测量指标表现出可接受的相对可靠性（组内相关系数（ICC）范围为 0.75 至 0.94）。然而，DEE 和 BTC 测试的测量值存在显著的测试间差异。同样，每个场测的测量精度都很差（表示为平均分数的百分比的测量误差标准偏差（CV）范围为 11.3%至 24.4%），最小可检测变化（MDC）显示干预后躯干伸展耐力测试的变化高于 42%，躯干弯曲耐力测试的变化高于 31.4%，才能表明测量误差之上的显著变化。因此，本研究的结果表明，只有 BTC 测试显示出可接受的测试间可靠性（ICC>0.9，CV10%，MDC30%），可以监测青少年在进行干预计划后可能出现的躯干耐力得分变化。
