The purpose of this study was to determine whether there is a linear relationship between the squat and a variety of hamstring resistance training exercises, and whether this relationship differs on the basis of sex. This study also sought to create prediction equations for the determination of hamstring exercise load based on the squat load. Repetition maximums of the squat, as well as 4 common hamstring resistance training exercises including the seated leg curl, stiff leg dead lift, single leg dead lift, and good morning exercise, were determined for each subject. Subjects included 21 men and 13 women collegiate athletes. Data were evaluated using linear regression analysis to predict hamstring exercise loads from 6 repetition maximum squat data. Results of the analysis of all subjects indicated that squat load was a significant predictor of loads for each of the hamstring exercises. However, separate analysis of women revealed that squat load was not a significant predictor of loads for any of the hamstring exercises. Analysis of the men revealed that squat was a significant predictor of load for the seated leg curl (R = 0.58, p < 0.001), stiff leg dead lift (R = 0.82, p < 0.001), single leg stiff leg dead lift (R = 0.80, p < 0.001), and good morning (R = 0.79, p < 0.001) exercises. On the basis of the analysis of the men, the following prediction equations were devised for each exercise: (1) seated leg curl load = squat load (0.186) + 10.935 kg, (2) stiff leg deadlift load = squat load (1.133) - 86.331 kg, (3) single leg stiff leg deadlift load = squat load (0.443) - 3.425 kg, and (4) good morning load = squat load (0.961) - 105.505 kg. Thus, results from testing core exercises such as the squat can provide useful data for the assignment of loads for assistance exercises.
本研究旨在确定深蹲与多种腘绳肌抗阻训练练习之间是否存在线性关系，以及这种关系是否因性别而异。本研究还试图根据深蹲负荷创建预测方程，以确定腘绳肌运动负荷。对每位受试者的深蹲重复最大值以及 4 种常见的腘绳肌抗阻训练练习（包括坐姿腿弯举、硬拉、单腿硬拉和早安练习）进行了测定。受试者包括 21 名男性和 13 名女性大学生运动员。使用线性回归分析评估数据，以根据 6 次重复最大深蹲数据预测腘绳肌运动负荷。所有受试者的分析结果表明，深蹲负荷是预测每种腘绳肌运动负荷的重要指标。然而，对女性的单独分析表明，深蹲负荷不是预测任何一种腘绳肌运动负荷的重要指标。对男性的分析表明，深蹲是坐姿腿弯举（R = 0.58，p < 0.001）、硬拉（R = 0.82，p < 0.001）、单腿硬拉（R = 0.80，p < 0.001）和早安练习（R = 0.79，p < 0.001）负荷的重要预测指标。基于对男性的分析，为每项练习制定了以下预测方程：（1）坐姿腿弯举负荷=深蹲负荷（0.186）+10.935 千克，（2）硬拉负荷=深蹲负荷（1.133）-86.331 千克，（3）单腿硬拉负荷=深蹲负荷（0.443）-3.425 千克，（4）早安负荷=深蹲负荷（0.961）-105.505 千克。因此，对深蹲等核心练习的测试结果可以为辅助练习的负荷分配提供有用的数据。
