Data are shown as mean ± standard deviation; differences between groups are calculated by independent samples t-test. Significant differences between hamstring injury group and not injured category are marked by asterisks (*p<0.05, **p<0.01, ***p<0.001).
Abbreviations: Q (Quadriceps), H (Hamstrings); “Dominant” refers to the kicking leg
