peak force, peak velocity, and peak power values were the highest during the propulsion phase of the force–time, velocity–time, and power–time data, respectively. The force at peak power and velocity at peak power were the values when peak power was expressed. To obtain those relative values, we

each measure. A 3 × 3 × 3 × 2 (group × angle × velocity × time) repeated-measures analysis of variance was used to explore interaction and main effects for H/Q FUNC . Significant interaction or main effects were further examined using Bonferroni-corrected post hoc tests. Main effects were calculated

second) was identified as the highest velocity produced after the onset of velocity. Acceleration (in degree per second squared) was calculated as the linear slope of the velocity-time curve (Δvelocity/Δtime) from velocity onset to 2 deg/s below the PV attained. The onset of velocity was defined as 2 deg

velocity–time data obtained from the radar device were fitted by an exponential function and derived to compute the net horizontal GRF. Individual linear force–velocity relationships were then extrapolated to calculate theoretical maximal force ( F 0 ; CV = 1.7%), velocity ( V 0 ; CV = 1.2%), 22 and the

calculated separately using the displacement and velocity time histories of the COP. DFA was computed for each COP component. The DFA scaling exponent ( α ) was estimated from signal windows ranging in size from 4 to 500 data points. DFA scaling exponent is conventionally interpreted to reflect white noise
