Abstract

PURPOSE

To compare the load-velocity relationship between 4 variants of the bench-press (BP) exercise.

METHODS

The full load-velocity relationship of 30 men was evaluated by means of an incremental loading test starting at 17 kg and progressing to the individual 1-repetition maximum (1RM) in 4 BP variants: concentric-only BP, concentric-only BP throw (BPT), eccentric-concentric BP, and eccentric-concentric BPT.

RESULTS

A strong and fairly linear relationship between mean velocity (MV) and %1RM was observed for the 4 BP variants (r > .96 for pooled data and r > .98 for individual data). The MV associated with each %1RM was significantly higher in the eccentric-concentric technique than in the concentric-only technique. The only significant difference between the BP and BPT variants was the higher MV with the light to moderate loads (20-70%1RM) in the BPT using the concentric-only technique. MV was significantly and positively correlated between the 4 BP variants (r = .44-.76), which suggests that the subjects with higher velocities for each %1RM in 1 BP variant also tend to have higher velocities for each %1RM in the 3 other BP variants.

CONCLUSIONS

These results highlight the need for obtaining specific equations for each BP variant and the existence of individual load-velocity profiles.

摘要

目的

比较卧推(BP)练习的4种变式之间的负荷-速度关系。

方法

通过递增负荷测试评估30名男性的完整负荷-速度关系,测试从17千克开始,在4种BP变式中逐渐增加到个人的1次重复最大值(1RM):仅向心卧推、仅向心卧推投掷(BPT)、离心-向心卧推和离心-向心BPT。

结果

观察到4种BP变式的平均速度(MV)与1RM百分比之间存在强且相当线性的关系(合并数据的r>0.96,个体数据的r>0.98)。与每种1RM百分比相关的MV在离心-向心技术中显著高于仅向心技术。BP和BPT变式之间唯一显著的差异是,在仅使用向心技术的BPT中,轻至中等负荷(20%-70%1RM)时MV更高。4种BP变式之间的MV显著正相关(r = 0.44-0.76),这表明在一种BP变式中,每种1RM百分比速度较高的受试者在其他3种BP变式中,每种1RM百分比的速度也往往较高。

结论

这些结果突出了为每种BP变式获取特定方程的必要性以及个体负荷-速度曲线的存在。
