Isokinetic Strength

After a 5-min cycloergometer (Monark LC4, Sweden) warm-up at moderate intensity and mobility exercises focused on lower-limbs, isokinetic strength tests were performed using a Biodex isokinetic dynamometer (System 4 Pro^TM, United States). The quadriceps (QUADS) and hamstrings (HAMS) torques were gravity corrected and the dynamometer calibration was made accordingly with the manufacturer’s instructions. Both legs were evaluated in a random order after verbal and visual instruction and feedback. After familiarization with the isokinetic movement (non-recorded two trials for each player), the players were tested over five repetitions of concentric knee extensions and flexions at 60°/s. The time of recovery between each repetition was 30 s. Isokinetic strength ratios were calculated from measurements of the maximal QUADS and HAMS peak torques. The test was performed in a room with a stable temperature (21°C) and relative humidity (55%). The following variables were determined: peak torque left anterior (quadriceps) (PTLQ); peak torque right anterior (quadriceps) (PTRQ); peak torque left posterior (hamstrings) (PTLP); peak torque right posterior (hamstrings) (PTRP); and quadriceps/hamstrings ratio (QUADS/HAMS).
