摘要

本研究旨在确定最佳最小速度阈值(MVT)是否能比一般和个别 MVT 更精确地估计六角杠铃举重(HBD)的单次最大重量(1RM)。我们使用三种 MVT 预测了 27 名阻力训练男性的 1RM 值:(i) 一般 MVT:1RM 试验中受试者的平均速度(0.25 m-s-1);(ii) 单个 MVT:1RM 试验中达到的速度;(iii) 最佳 MVT:消除实际和预测 1RM 值之间差异的 MVT。考虑到五种(30-50-70-80%1RM)或六种(30-50-70-80-90%1RM)负荷条件,建立了两种个人负荷-速度关系模型。在实际和六个预测的 1RM 之间观察到了微小的差异(效应大小 < 0.20)、较低的绝对误差(< 实际 1RM 的 5%)和极高的相关性(r > 0.90)。唯一的显著差异是 90%1RM 条件下的原始误差(0.60 ± 7.34 千克)低于 80%1RM 条件下的原始误差(2.27 ± 7.54 千克;p = 0.013)。这些结果表明,个体负荷-速度关系可准确估计阻力训练男性的 HBD 1RM 值,而且这些估计值在不同类型的 MVT(一般、个体和最佳)和最终测试负荷(80%1RM 和 90%1RM)中可保持相似的精度水平。

Hexagonal Barbell Deadlift One-repetition Maximum Estimation Using Velocity Recordings.

This study aimed to determine whether the optimal minimal velocity threshold (MVT) provides more precise estimates of one-repetition maximum (1RM) in the hexagonal barbell deadlift (HBD) than the general and individual MVTs. The 1RMs of 27 resistance-trained males were predicted using three types of MVT: (i) General MVT: averaged across subjects' velocity of the 1RM trial (0.25 m·s-1), (ii) individual MVT: velocity attained during the 1RM trial, and (iii) Optimal MVT: MVT that eliminated the differences between the actual and predicted 1RM. Two individual load-velocity relationships were modelled considering five (30-50-70-80%1RM) or six (30-50-70-80-90%1RM) loading conditions. Negligible differences (Effect size<0.20), low absolute errors (<5% of the actual 1RM), and extremely high correlations (r>0.90) were observed between the actual and six predicted 1RMs. The only significant difference was the lower raw errors for the 90%1RM condition (0.60±7.34 kg) compared to the 80%1RM condition (2.27±7.54 kg; p=0.013). These results suggest that the individual load-velocity relationship offers an accurate estimation of the HBD 1RM in resistance-trained males, and these estimates could maintain similar levels of precision across different types of MVT (general, individual, and optimal) and final tested loads (80%1RM and 90%1RM).
