Trunk rotator strength plays an important role in sports performance and health. A reliable method to assess these muscles with functional electromechanical dynamometer has not been described. Therefore, the objectives of this paper were (I) to explore the reliability of different strength variables collected in isokinetic and isometric conditions during two trunk rotator exercises, and (II) to determine the relationship of isometric and dynamic strength variables collected in the same exercise.
A repeated measures design was performed to evaluate the reliability of the horizontal cable woodchop (HCW) and low cable woodchop (LCW) exercises. Reliability was assessed using -tests of paired samples for the effect size, the standard error of measurement, the coefficient of variation (CV) and the intraclass correlation coefficient (ICC). The Pearson's () correlation coefficient was used to explore the association between isometric and isokinetic tests.
HCW exercise is more reliable than LCW exercise in assessing trunk rotator muscles. The strength manifestation that should be used is the average strength, and the most reliable evaluation was the HCW at 0.40 m·s concentric (ICC = 0.89; CV = 10.21%) and eccentric (ICC = 0.85; CV = 9.33%) contraction and the dynamic condition that most correlated with the isometric was LWC at 0.50 m·s ( = 0.83; < 0.01).
HCW is a reliable exercise to measure trunk rotator muscles.
躯干旋转肌力量在运动表现和健康中起着重要作用。尚未描述一种使用功能性电动测力计评估这些肌肉的可靠方法。因此，本文的目的是：（I）探讨在两种躯干旋转练习中，等速和等长条件下收集的不同力量变量的可靠性；（II）确定在同一练习中收集的等长和动态力量变量之间的关系。
采用重复测量设计来评估水平缆索伐木（HCW）和低位缆索伐木（LCW）练习的可靠性。使用配对样本的检验来评估可靠性，包括效应量、测量标准误差、变异系数（CV）和组内相关系数（ICC）。使用Pearson（）相关系数来探讨等长和等速测试之间的关联。
在评估躯干旋转肌方面，HCW练习比LCW练习更可靠。应使用的力量表现形式是平均力量，最可靠的评估是在0.40 m·s同心（ICC = 0.89；CV = 10.21%）和离心（ICC = 0.85；CV = 9.33%）收缩时的HCW，与等长最相关的动态条件是在0.50 m·s时的LWC（ = 0.83；< 0.01）。
HCW是测量躯干旋转肌的可靠练习。
