Objective The risk of anterior cruciate ligament (ACL) injury in athletes can be reduced by incorporating motor learning approaches into injury prevention training programs. Therefore, this study aims to investigate the effect of variability-based motor learning approaches on kinetic and kinematic factors related to ACL injury in athletes.
Methods Searches were conducted in PubMed, Google Scholar, Scopus, Science Direct, and Elsevier databases for articles published between 2010 and 2024. The keywords ("ACL" OR "anterior cruciate ligament"), ("differential learning"), ("nonlinear pedagogy"), ("variability"), and ("biomechanics" OR "kinematics" OR "kinetics") were used independently and in combination.
Results Results After applying the inclusion and exclusion criteria, six studies were included in the final analysis. The results indicated that variability-based training, including differential and nonlinear learning, increased trunk and hip flexion, increased knee flexion, decreased knee valgus and abduction, and increased ankle dorsiflexion. Additionally, increased hip abduction and external rotation, increased ankle dorsiflexion moment, decreased knee valgus and abduction moments, and reduced ground reaction force were observed in athletes.
Conclusion Compared to differential learning, exercises based on nonlinear pedagogy more effectively improve biomechanical factors related to ACL injury in athletes. It is recommended that coaches and trainers incorporate variability-based approaches, particularly nonlinear pedagogy, to reduce injury risk, enhance rehabilitation programs, and improve ecological validity.
