The main aim of this study was to investigate differences between the functional hamstring to quadriceps (H:Qfunc) and conventional hamstring to quadriceps (H:Qconv) ratios between the Czech first league soccer players with different game positions.This study adopted a cross-sectional study design. A total of 104 soccer players from the Czech Republic 1st league teams, including 11 goalkeepers, 34 defenders, 35 midfielders and 24 forwards. The participants performed the knee concentric extension/concentric flexion and eccentric extension/concentric flexion tests with their maximum strength. The maximal range of movement was defined between 180 (full knee extension) to 100, and the players performed the test at an angular velocity of 60/s for concentric/concentric contraction and 30/s for eccentric contraction. As for angle-specific H:Q ratio calculation, the hamstrings eccentric concentric angle-specific torque, at each knee-joint angle, was divided by the quadriceps concentric angle-specific torque, at the same knee-joint angle. For calculation of the non-angle-specific conventional H:Q ratio, the hamstrings eccentric and concentric peak torques were divided by the quadriceps concentric peak torque.This study adopted a cross-sectional study design.
