Isometric strength tests are gaining popularity in recent years. However, no study has validated any isometric strength tests to assess upper body pulling ability. The aim of this study was to investigate the validity and reliability of isometric prone bench pull. Twenty-three resistance trained athletes (age: 26±4 years, height: 1.75±0.07 m, body mass: 78.6±11.5 kg) were required to perform prone bench pull 1 repetition maximum and isometric prone bench pull tests during the familiarization and actual testing sessions. Isometric prone bench pull was performed at 90 and 120 elbow angles. Peak force and rate of force development measures were highly reliable with intra-correlation coefficient between 0.881-0.987. Peak force obtained from isometric prone bench pull at both elbow angles showed large correlations to prone bench pull 1 repetition maximum (r=0.833-0.858, p<0.01). Linear regression equations to predict 1RM performance from isometric prone bench pull peak force produced an estimated 1RM with a standard error of only 3-6% of the average prone bench pull 1 repetition maximum. The current findings show that isometric prone bench pull is a reliable test and can be used to predict prone bench pull performance.
近年来，等长力量测试越来越受欢迎。然而，目前还没有研究验证任何等长力量测试来评估上半身的拉力能力。本研究的目的是探讨等长俯姿拉力的有效性和可靠性。23 名经过抗阻训练的运动员（年龄：26±4 岁，身高：1.75±0.07m，体重：78.6±11.5kg）在熟悉和实际测试期间需要进行 1 次最大俯姿拉力和等长俯姿拉力测试。等长俯姿拉力在 90 和 120 度肘角下进行。峰值力和力量发展速率的测量具有高度可靠性，内相关系数在 0.881-0.987 之间。在两个肘角下，从等长俯姿拉力中获得的峰值力与俯姿拉力 1 次最大重复次数（r=0.833-0.858，p<0.01）高度相关。从等长俯姿拉力的峰值力预测 1RM 表现的线性回归方程产生了一个估计的 1RM，其标准误差仅为平均俯姿拉力 1 次最大重复次数的 3-6%。目前的研究结果表明，等长俯姿拉力是一种可靠的测试方法，可以用来预测俯姿拉力的表现。
