Abstract
Introduction: Using specific training in basketball can reduce the possibility of non-collision injuries in athletes. Anterior Cruciate Ligament (ACL) injury prevention, more effective with a different way of motor learning. The aim of this study was to investigate the effect and persistence of motor learning training and perturbation training on strength, balance, and performance of lower extremities in professional basketballist susceptible to injury of ACL.
Methodology: The research population was all male professional basketballist aged 20 to 35 years who had defects in the ratio of hamstring to quadriceps strength (less than 80 percent) of the knee joint in the city of Isfahan. 36 athletes were purposefully selected from among these athletes as research samples. The screened samples were randomly divided into three groups of motor learning training, perturbation training and control group in equal numbers (n=12).At the beginning, before starting the training, the strength of the hamstrings and quadriceps muscles was evaluated with manual dynamometer, static and dynamic balance with the stork and Y tests, respectively, and the performance of the lower limbs with Single triple hopping tests. The experimental groups performed their training programs for 4 weeks, 3 sessions per week and each session lasted 45 minutes; while the control group did only specific basketball exercises. After the end of the training, the subjects of all three groups participated in the post-tests, which were similar to the pre-test, and after 4 weeks of non-training, the previous tests were repeated for follow-up. Data were analyzed through the repeated measurements and Bonferroni's post hoc test at the error level (P˂ 0.05).
Results:The results showed a significant effect of perturbation training and motor learning training on hamstring and quadriceps muscle strength, static and dynamic balance and lower limb performance (P<0.05). The results showed that both training programs were persistent in the variables of strength and static balance (P<0.05).
Conclusion: perturbation training and motor learning improved the balance, strength and function of the lower limbs of male basketball athletes susceptible to ACL injury. Therefore, to prevent ACL injury in basketball athletes, these training are recommended to coaches and athletes.
