Gillingham, B, Bishop, A, Higa, GK, Adams, KJ, and DeBeliso, M. The relationship between partial and full range of motion deadlift 1-repetition maximum: a technical note. J Strength Cond Res 37(4): 909-914, 2023-The full range of motion (FROM) or partial range of motion (PROM) deadlift (DL) are often included in resistance training (RT) programs and are performed by strength athletes in competition. This study examined the relationship between the FROM and PROM 1-repetition maximum (1RM) DL and if the PROM 1RM DL can be estimated by the FROM 1RM DL. Eighteen National Collegiate Athletic Association wrestlers (20.8 ± 1.2 years, 176.0 ± 5.2 cm, 78.9 ± 10.6 kg) performed a warm-up followed by the assessment of the FROM and PROM 1RM DLs. The FROM DLs were executed with a starting position of the bar resting on the lifting platform. Partial range of motion DLs were executed in a power rack with the bar starting position at ≈2.54 cm above the patella. Regression analysis was employed to estimate PROM 1RM DL based on FROM 1RM DL, body height, and mass. A Pearson's correlation coefficient ( r ) was used to compare the PROM 1RM DL with FROM 1RM DL. A dependent t test was used to compare the PROM 1RM DL and FROM 1RM DL scores (α < 0.05). The PROM 1RM DL scores (226.0 ± 40.6 kg) were significantly greater than the FROM 1RM DL scores (191.7 ± 37.2 kg) ( p < 0.05: effect size = 0.92). The PCC between the PROM and FROM 1RM DL was r = 0.85 ( p < 0.05). The regression coefficient for the FROM 1RM DL was significant ( p < 0.05; R = 0.85, R2 = 0.73). The regression coefficients for body mass and height were not significant ( p > 0.05). The PROM and FROM DL may be interchangeable modalities within an RT program, and the PROM 1RM DL can be accurately predicted by the FROM 1RM DL.
吉利厄姆，B、毕晓普，A、希加，GK、亚当斯，KJ和德贝利索，M。全范围和部分范围动作硬拉1次重复最大值之间的关系：一篇技术说明。《力量与体能研究杂志》37(4): 909 - 914，2023年——全范围动作（FROM）或部分范围动作（PROM）硬拉（DL）经常被纳入阻力训练（RT）计划，并且由力量型运动员在比赛中进行。本研究考察了全范围动作和部分范围动作的1次重复最大值（1RM）硬拉之间的关系，以及部分范围动作1RM硬拉是否可以通过全范围动作1RM硬拉来估计。18名美国国家大学体育协会摔跤运动员（20.8±1.2岁，176.0±5.2厘米，78.9±10.6千克）进行了热身，随后评估了全范围动作和部分范围动作的1RM硬拉。全范围动作硬拉的起始姿势是杠铃放在举重台上。部分范围动作硬拉在力量训练架上进行，杠铃起始位置在髌骨上方约2.54厘米处。采用回归分析，根据全范围动作1RM硬拉、身高和体重来估计部分范围动作1RM硬拉。使用皮尔逊相关系数（r）来比较部分范围动作1RM硬拉和全范围动作1RM硬拉。使用配对t检验来比较部分范围动作1RM硬拉和全范围动作1RM硬拉的得分（α<0.05）。部分范围动作1RM硬拉得分（226.0±40.6千克）显著高于全范围动作1RM硬拉得分（191.7±37.2千克）（p<0.05；效应大小=0.92）。部分范围动作和全范围动作1RM硬拉之间的皮尔逊相关系数为r = 0.85（p<0.05）。全范围动作1RM硬拉的回归系数显著（p<0.05；R = 0.85，R2 = 0.73）。体重和身高的回归系数不显著（p>0.05）。在阻力训练计划中，部分范围动作和全范围动作硬拉可能是可互换的训练方式，并且部分范围动作1RM硬拉可以通过全范围动作1RM硬拉准确预测。
