Abstract |
Introduction: Many non-contact injuries of the anterior cruciate ligament (ACL) occur when the athlete is exposed to cognitive perturbation. In futsal, for example, the player must attention on the opponent's movements while jumping and landing, which changes the biomechanical pattern of the landing, including increasing the dynamic knee valgus angle and decreasing the knee flexion. Doing neuromuscular exercises with cognitive tasks at the same time causes the retraining of safe movement patterns in a person's central nervous system similar to what happens in competition conditions. This simulation of sports specific movements is likely to be effective in reducing the risk of ACL injury. Therefore, the aim of this study was to investigate the effect of eight weeks of neuromuscular training with dual cognitive tasks on the performance and angle of dynamic knee valgus and knee flexion in futsal players with ligament dominance deficit. Method: Thirty subjects with knee ligament dominance defects (mean age: 21.86 ± 3.27, weight: 68.91 ± 99.55, height: 175.6 ± 6.49) were identified by tuck jump test and were randomly divided into control (N=15) and experimental (N=15) groups. The experimental group performed Training for eight weeks and the control group continued their daily life. Dynamic knee valgus angle and knee flexion were assessed by drop vertical jump test were evaluated by video camera and Kinovea software and performance by single leg triple hop for distance test. Independent t-test and univariate analysis of covariance in SPSS 25 software were used to analyze the data. Results: Significant difference in the dynamic knee valgus angle at the during phases initial contact (P=0.01) and maximum flexion (P=0.02), the knee flexion angle at initial contact (P=0.015) and maximum knee flexion (P=0.001) and single leg triple hop for distance test (P= 0.001) in the experimental group was observed in comparison with the control group. Conclusion: According to the results of the present study, it seems that combining neuromuscular training with dual cognitive tasks is a suitable approach to reduce the risk of ACL injury and improve performance. |
