Sport-Specific Differences in Power–Velocity–Force Profiling during Trunk Rotations at Different Loads
This study investigates differences in power and velocity at different loads and power and force at different velocities during trunk rotations in athletes who practice sports with rotational demands on the trunk. Athletes of combat (n = 23), fighting (n = 39), ball (n = 52) and water sports (n = 19...

This study investigates differences in power and velocity at different loads and power and force at different velocities during trunk rotations in athletes who practice sports with rotational demands on the trunk. Athletes of combat (n = 23), fighting (n = 39), ball (n = 52) and water sports (n = 19) with a mean age of 23.8 ± 1.5 years performed standing trunk rotations on each side with bars of different weights (from 1 kg up to 50 kg) placed on their shoulders. The findings showed significant between-group differences in mean power in the acceleration phase of trunk rotations, especially at higher weights (≥10.5 kg) or lower velocities (≤334.2 rad/s). The power at 10.5 kg was significantly higher in fighting than water (<i>p</i> = 0.035; d = 0.86), combat (<i>p</i> = 0.001; d = 1.53) and ball sports athletes (<i>p</i> = 0.001; d = 1.48), with no significant differences between the two latter groups; at 15.5 kg, it was higher in water than combat (<i>p</i> = 0.027; d = 0.91) and ball sports athletes (<i>p</i> = 0.009; d = 1.17) but not those in fighting sports; and at 20 kg, it was higher in water than combat (<i>p</i> = 0.013; d = 0.98) and ball sports athletes (<i>p</i> = 0.006; d = 1.33), with no significant differences with those in fighting sports.
