A study comparing coaching methods for reducing ACL injury risk in basketball found that variability and degeneracy can be effective. The importance of movement variability in reducing injury risk is explored, along with different approaches like nonlinear pedagogy and constraint-led approach. Gender representation in training groups and its impact on change of direction performance is examined. Traditional coaching methods are compared with alternative approaches like nonlinear pedagogy and constraint-led approach. A study highlights the effectiveness of constraint-led approach in reducing ACL injury risk. The potential of practice variability in reducing the risk of ACL injury is also discussed.
