TÓM TẮT
Background: Futsal players have a higher injury rate than football players. Knee injuries are one of the most serious injuries, greatly affecting sports performance and career life.Purpose: The main aim of this study was to investigate knee isokinetic strength and H/Q ratio in elite Vietnamese futsal players.Methods: Eighteen Vietnamese elite male futsal players (20.79 ± 3.18) participated in the study. The testing protocol required players to perform concentric contractions of both quadriceps and hamstring muscles at angular velocities of 600.s-1 and 2400.s-1. Conventional hamstrings/quadriceps (H/Q) ratios were calculated.Results: In the dominant leg, the knee extension movement had peak torque values at two speeds of 600.s-1 and 2400.s-1, respectively 214.39 ± 13.88 Nm and 117.07 ± 10.87Nm. The ratio of hamstring/quadriceps to dominant leg strength is 44.93 ± 10.09. The mean values of this study revealed lower than thenorms recommended by the Biodex Multi-Joint System, Clinical Resource Manual criteria.Conclusion: Vietnam's elite futsal athletes have moderate and low strength values. The hamstring/quadriceps ratio is lower than the published standard values, which increases the risk of injury.
