BACKGROUND
The maximal one-repetition test (1-RM) is widely used in scientific research; however, there are conflicting results regarding its reproducibility in elderly populations. The present study aimed to analyze the reproducibility of the test both before and after a 12-week training period by using the bench press and leg press 45° 1-RM tests in the elderly, taking into consideration the training experience and strength level of the women.
METHODS
Elderly women (n = 376; age, 68.5 ± 14.1 years; height, 162.7 ± 5.5 cm; body mass, 71.2 ± 16.0 kg) who underwent ≥3 months of resistance training performed an initial week of familiarization and a second week of testing and retest, with a 48⁻72 h interval.
RESULTS
The results showed that Kappa indices ranged from 0.93 to 0.95, and the intraclass correlation coefficients were 0.99 for both the lower and upper limbs. In addition, minimal detectable changes were found that ranged between 1 and 3%, which means that changes lower than 1 kg could be detected.
CONCLUSION
The present study confirms that the 1-RM test has high reliability and reproducibility in the elderly, for both upper and lower limbs.
背景
最大重复次数测试（1-RM）在科学研究中被广泛使用；然而，关于其在老年人群中的可重复性存在相互矛盾的结果。本研究旨在通过对老年人进行卧推和45°腿举1-RM测试，分析在为期12周的训练期前后该测试的可重复性，并考虑女性的训练经验和力量水平。
方法
接受了≥3个月抗阻训练的老年女性（n = 376；年龄，68.5±14.1岁；身高，162.7±5.5厘米；体重，71.2±16.0千克）进行了为期一周的熟悉期训练，以及为期一周的测试和重新测试，间隔时间为48 - 72小时。
结果
结果显示，卡帕指数范围为0.93至0.95，下肢和上肢的组内相关系数均为0.99。此外，发现最小可检测变化范围在1%至3%之间，这意味着可以检测到低于1千克的变化。
结论
本研究证实，1-RM测试在老年人的上肢和下肢中具有高可靠性和可重复性。
