DATASET FOR STUDY: The Contribution of Braking Rate of Force Development and Braking Impulse to Push-Off Force Distribution and Jump Performance: An Exploratory Study.

This is raw data for an exploratory study investigated the relationships between eccentric force characteristics (braking rate of force development (RFD) and braking impulse) and phase-specific concentric (push-off) force application and jump height during bilateral and unilateral countermovement jumps (CMJs). Data from 206 physically active individuals (basketball players and students) were retrospectively analyzed. Jump height showed strong positive correlations with concentric impulse in both the early and late halves of the push-off phase (r ≈ .61–.71), with slightly stronger associations observed for the late push-off impulse. Notably, the ratio of early- to late push-off phase impulse was also related to jump height (r ≈ -.61–. -71), suggesting that a more evenly distributed or late-phase-oriented force profile is advantageous to performance. Eccentric braking impulse demonstrated moderate positive associations with both early-concentric impulse (r ≈ .29–.53) and jump height (r ≈ .38–.48), but not with late-concentric impulse. Braking RFD was positively associated with early-concentric impulse (r ≈ .29–.53), but showed weak or non-significant associations with jump height and late-concentric impulse, particularly in unilateral jumps. These findings emphasize the importance of force distribution timing and highlight the need for future confirmatory research to test the hypotheses generated by this exploratory analysis.
