RSR, relative strength ratio (1RM strength divided by body mass), with range indicated in brackets [minimum–maximum]; MPV, mean propulsive velocity; G1, G2 and G3 are 3 subgroups of the total (n=80) study sample. Eta-squared (η 2 ) is reported as a measure of the effect size in the one-way ANOVA comparison between the subgroups
† All groups significantly different from each other (P<0.05)
Ψ Significantly different from G1 (P<0.05); ΨΨΨ Significantly different from G1 (P<0.001)
*** Significantly different from G3 (P<0.001)
Values are mean±SD
