Abstract

This study aimed at (1) evaluating the linearity of the force-velocity relationship, as well as the reliability of maximum force (F0), maximum velocity (V0), slope (α), and maximum power (P0); (2) comparing these parameters between the traditional and ballistic bench press (BP); and (3) determining the correlation of F0 with the directly measured BP 1-repetition maximum (1RM). Thirty-two men randomly performed 2 sessions of traditional BP and 2 sessions of ballistic BP during 2 consecutive weeks. Both the maximum and mean values of force and velocity were recorded when loaded by 20-70% of 1RM. All force-velocity relationships were strongly linear (r > 0.99). While F0 and P0 were highly reliable (ICC [intraclass correlation coefficient]: 0.91-0.96, CV [coefficient of variation]: 3.8-5.1%), lower reliability was observed for V0 and α (ICC: 0.49-0.81, CV: 6.6-11.8%). Trivial differences between exercises were found for F0 (ES [effect size] < 0.2), however the α was higher for the traditional BP (ES: 0.68-0.94), and V0 (ES: 1.04-1.48) and P0 (ES: 0.65-0.72) for the ballistic BP. The F0 strongly correlated with BP 1RM (r: 0.915-0.938). The force-velocity relationship is useful to assess the upper-body maximal capabilities to generate force, velocity, and power.
