The purpose of this study was to investigate ball speed predictors of slide attacks and provide direct parameters for their proper execution. Healthy collegiate female volleyball players (n = 8) were recruited. After a warm-up, 3 successful slide attacks per participant and their ball speed were recorded using an 8-camera motion capture system and a radar gun. COM approach speed, maximum angular velocity of pelvis and torso rotation in the arm cocking phase, and maximum angular velocity of torso rotation, shoulder IR, and elbow extension in the arm acceleration phase were calculated for the trial with the fastest ball speed. The multiple stepwise regression was not statistically significant (p = .098). The findings indicate that peak torso rotation angular velocity in the arm cocking phase and peak shoulder IR and peak elbow extension angular velocities in the arm acceleration phase may be important contributors to the ball speed in slides.
