| Note. Values are presented as mean ± standard deviation. V0: No overspeed load; OS: overspeed load (1: 2 kg; 2: 4 kg; 3: 5.25 kg); V5m: Mean velocity between 40-m and 45-m from a flying start; SL: Step length; SR: Step rate; CT: Contact time; FT: Flight time; HD: Horizontal distance between the first contact point and the vertical projection of center of masses. r(B): matched rank biserial correlation effect size. *: p ≤ .05 different to pre-test values; CI: Confidence interval. | |||||
