| Background:Due to the crucial nature of knee joint stability in basketball players and the possible role of the rate of torque development hamstrings to quadriceps ratio for determining knee joint stabilityin the early phase of explosive movements, the purpose of this cross sectional study was to explore the relationshipbetween the rate of torque development hamstrings to quadriceps ratio and biomechanical parameters of hip and knee joints in sagittal and frontal planes during the drop vertical jump test. Methods: 20 healthy male recreational basketball players (aged 15-18) were recruited. After measuring anthropometric data, rate of torque development hamstrings to quadriceps ratio was assessed using an isokinetic Biodex system. Biomechanical variables were measured using motion analysis system during drop vertical jump test. Results: rate of torque development hamstrings to quadriceps ratio (0-50milliseconds) was negatively correlated with knee abduction angle (p= 0.028), knee adduction angle (p= 0.003), knee abduction moment (p= 0.023), knee joint range of motion in frontal plane (p= 0.01) during 17-50ms after initial contact. Other biomechanical parameters did not have a significant correlation with rate of torque development hamstrings to quadriceps ratio. Conclusion:The results of this study revealed that the rate of torque development hamstrings to quadriceps ratio was negatively associated with knee kinematic and kinetic parameters. Based on the outcomes of this study and previous investigations, it can be acknowledged that therate of torque development hamstrings to quadriceps ratio might be a useful tool to add to the athlete's injury screening. | ||
