The aim of this study was to evaluate the reliability and agreement between the test and retest of the 10-repetition maximum (10-RM) test for leg press and bench press in breast cancer survivors (BCS). Thirty-one BCS participated in this study, age 54.87 ± 5.7 years. All performed 10-RM tests and retests for the leg press 45° and the bench press. For reliability analyses, an intraclass coefficient correlation (ICC) and coefficient of variation (CV) were performed. The limits of agreement were calculated using a Bland-Altman plot with 95% CIs. For absolute and relative error of measurement, we used standard error of measurement and minimally detectable change. The result showed a high reliability for the bench press and leg press; ICC of 0.94 and 0.98, respectively. CV was <10% for both exercises. The systematic error were 1.5 kg (10%) and 6.1 (8%) for the bench press and leg press, respectively. The standard errors of measurements were 0.96 kg (6.08%) and 4.11 kg (5.27%) for the bench press and leg press, respectively. The minimally detectable changes were 2.72 kg (17.20%) and 5.62 kg (7.21%) for the bench press and leg press, respectively. In breast cancer survivors, the muscular strength measurement for the 10-RM test showed a high to very high rate of reliability and agreement, with acceptable error of measurement.
本研究的目的是评估乳腺癌幸存者（BCS）进行腿举和卧推的10次最大重复量（10-RM）测试时，测试与复测之间的可靠性和一致性。31名BCS参与了本研究，年龄为54.87±5.7岁。所有人都进行了45°腿举和卧推的10-RM测试及复测。对于可靠性分析，进行了组内相关系数（ICC）和变异系数（CV）分析。使用带有95%置信区间的Bland-Altman图计算一致性界限。对于测量的绝对误差和相对误差，我们使用了测量标准误差和最小可检测变化。结果显示卧推和腿举具有高可靠性；ICC分别为0.94和0.98。两种练习的CV均<10%。卧推和腿举的系统误差分别为1.5千克（10%）和6.1（8%）。卧推和腿举的测量标准误差分别为0.96千克（6.08%）和4.11千克（5.27%）。卧推和腿举的最小可检测变化分别为2.72千克（17.20%）和5.62千克（7.21%）。在乳腺癌幸存者中，10-RM测试的肌肉力量测量显示出高到非常高的可靠性和一致性，且测量误差可接受。
