The purpose of this study was to determine whether there is a linear relationship between the squat and a variety of quadriceps resistance training exercises for the purpose of creating prediction equations for the determination of quadriceps exercise loads based on the squat load. Six-repetition maximums (RMs) of the squat, as well as four common resistance training exercises that activate the quadriceps including the deadlift, lunge, step-up, and leg extension, were determined for each subject. Subjects included 21 college students. Data were evaluated using linear regression analysis to predict quadriceps exercise loads from 6RM squat data and were cross-validated with the prediction of sum of squares statistic. Analysis of the data revealed that the squat is a significant predictor of loads for the dead lift (R2 = 0.81, standard error of the estimate [SEE] = 12.50 kg), lunge (R2 = 0.62, SEE = 12.57 kg), step-up (R2 = 0.71, SEE = 9.58 kg), and leg extension (R2=0.67, SEE = 10.26 kg) exercises. Based on the analysis of the data, the following 6RM prediction equations were devised for each exercise: (a) deadlift load = squat load (0.83) + 14.92 kg, (b) lunge load = squat load (0.52) + 14.82 kg, (c) step-up load = squat load (0.50) + 3.32 kg, and (d) leg extension load = squat load (0.48) + 9.58 kg. Results from testing core exercises such as the squat can provide useful data for the assignment of loads for other exercises.
本研究的目的是确定深蹲与各种股四头肌抗阻训练练习之间是否存在线性关系，以便创建基于深蹲负荷来确定股四头肌练习负荷的预测方程。为每位受试者测定了深蹲的6次重复最大值（6RM），以及包括硬拉、弓步蹲、上台阶和腿弯举在内的四种激活股四头肌的常见抗阻训练练习的6RM。受试者包括21名大学生。使用线性回归分析对数据进行评估，以根据深蹲6RM数据预测股四头肌练习负荷，并通过平方和统计量的预测进行交叉验证。数据分析表明，深蹲是硬拉（R2 = 0.81，估计标准误[SEE] = 12.50 kg）、弓步蹲（R2 = 0.62，SEE = 12.57 kg）、上台阶（R2 = 0.71，SEE = 9.58 kg）和腿弯举（R2 = 0.67，SEE = 10.26 kg）练习负荷的显著预测指标。基于数据分析，为每项练习设计了以下6RM预测方程：（a）硬拉负荷 = 深蹲负荷（0.83）+ 14.92 kg，（b）弓步蹲负荷 = 深蹲负荷（0.52）+ 14.82 kg，（c）上台阶负荷 = 深蹲负荷（0.50）+ 3.32 kg，以及（d）腿弯举负荷 = 深蹲负荷（0.48）+ 9.58 kg。诸如深蹲等核心练习的测试结果可为其他练习的负荷分配提供有用数据。
