Sprinting, Change of Direction Ability and Horizontal Jump Performance in Youth Runners According to Gender

.3–0.5, moderate; < 0.5–0.7, large; < 0.7–0.9, very large; and < 0.9–1.0, almost perfect ( Hopkins et al., 2009 ). Data analysis was performed using the Statistical Package for Social Sciences (version 20.0 for Windows, SPSS™ Inc, Chicago, IL, USA) for Windows. Statistical significance was set at p < 0.05. Results The results of the physical performance in sprint, CODA and HJ tests of the total sample, boys and girls are described in Table 2 . The CV of all the physical tests were between 1.9 and 4.9%. No significant differences ( p > 0.05, d < 0.10, trivial) were

Shorter but More Frequent Rest Periods: No Effect on Velocity and Power Compared to Traditional Sets not Performed to Failure

. Results Mean ± SDs for MV, MP, and RPE are presented in Figures 2 and 3 . There were no differences between RR6 and TS in MV ( Figure 2A; p > 0.05; d = 0.10 (-0.35, 0.56)), MP ( Figure 2B; p > 0.05; d = 0.19 (-0.27, 0.64)), MVD ( Figure 4 ; p > 0.05; d = 0.16 (-0.30, 0.62)), MPD ( p > 0.05; d = 0.22 (-0.24, 0.68)), MVM ( Figure 5 ; p > 0.05; d = 0.12 (0.34, 0.56)), or MPM ( p > 0.05; d = 0.09 (-0.36, 0.55)).

The relative contribution of physical fitness to the technical execution score in youth rhythmic gymnastics

execution score. Differences between gymnasts of a higher and lower performance level were determined using independent samples t-tests. Cohen (d) effect sizes were calculated and their magnitude was categorized as follows: trivial, <0.2; small, 0.2 to 0.5; small to moderate, 0.5 to 0.8, and large, >0.8 (Cohen, 1988). Multiple regression analysis was used to investigate which physical fitness variables contributed most significantly to the technical execution score in each group separately. Test–retest reliability for all the dependent variables measured in this
