Data are presented as means ± SD’s and represent isometric peak torque values (in Nm/kg), ranges (min-max values) and ratios (peak strength of m.Hamstrings divided by peak strength of m. Quadriceps, in %) of m. Quadriceps and m. Hamstrings of the dominant (D) and non-dominant (ND) leg, per player positions following 2 maximal isometric contractions (4 s) in a 45° (M. Hamstrings) or 90° (m. Quadriceps) knee-angle (relative to the horizontal plane). ǂp < 0.05 compared to the opposite leg in all groups
