椎旁肌耐力受损可能导致持续性腰痛（LBP），通常使用Biering-Sørensen测试进行单次重复评估。本研究调查了Sørensen测试持续时间，肌肉激活和肌肉疲劳性如何受到多次重复测试的影响，并确定了有和没有LBP病史的年轻活跃成年人Sørensen测试持续时间的预测因素。64名有和没有持续性LBP的人重复进行了3次Sørensen测试。计算腰、胸椎旁肌和腘绳肌的激活幅度和中值频率斜率（疲劳性）。在LBP患者中，第2次和第3次重复测试的持续时间明显缩短。在没有LBP的个体中，腰椎椎旁肌的疲劳性是测试持续时间的最佳预测因子。在患有LBP的个体中，Sørensen测试持续时间通过腘绳肌的疲劳性和胸腰椎椎旁肌的激活幅度来预测。我们的研究结果表明，有必要扩大Sørensen测试的难度，以阐明年轻活跃的LBP成年人的损伤。旨在改善LBP患者腰椎椎旁表现的训练计划应在耐力运动期间监测其他腹肌的表现。
Impaired paraspinal muscle endurance may contribute to persistent low back pain (LBP) and is frequently assessed using a single repetition of the Biering-Sørensen test. This study investigated how Sørensen test duration, muscle activation, and muscle fatigability are affected by multiple repetitions of the test, and determined predictors of Sørensen test duration in young, active adults with and without a history of LBP. Sixty-four individuals with and without persistent LBP performed 3 repetitions of the Sørensen test. Amplitude of activation and median frequency slope (fatigability) were calculated for the lumbar and thoracic paraspinals and the hamstrings. Duration of the test was significantly less for the 2nd and 3rd repetitions in individuals with LBP. In individuals without LBP, fatigability of the lumbar paraspinals was the best predictor of test duration. In individuals with LBP, Sørensen test duration was predicted by fatigability of the hamstrings and amplitude of activation of the thoracic and lumbar paraspinals. Our findings demonstrate that it is necessary to amplify the difficulty of the Sørensen test to elucidate impairments in young, active adults with LBP. Training programs aiming to improve lumbar paraspinal performance in individuals with LBP should monitor performance of other synergist muscles during endurance exercise.
