Introduction and purpose:The complexity of training exercises and the issue of individual differences have created many challenges for motor skills trainers.New educational methods, such as methods based on non-linear pedagogy, while making training more diverse and attractive, probably prepares the human control system more to face the dynamic environment of field sports than linear methods. as result The aim of this study is to compare the effectiveness of linear and non-linear training methods in facilitating the acquisition of coordination in basketball free throw.
Materials and methods: Forty-five boys (average age = 9±1.2 years) were randomly assigned to the linear learning group and tow training groups by manipulating task constraints and differential training as a nonlinear method to learn basketball free throw skills in 8 practice sessions in 4weeks. Measurement of performance and changes in coordination were investigated by the pre-test-post-test method with a kinematic motion analysis and IMU measure units. In order to analyze the data, the analysis of variance test with repeated measurements and the paired t-test were used to compare the RMSe scores.
Results: The results showed that the variability of the coordination of the wrist and elbow joints improved significantly in the task constraints manipulation group (P ≤ .01) and the accuracy scores in the tow nonlinear groups increased significantly, and this improvement was far greater for the task constraints manipulation group than the other two groups.
Discussion and Conclusion: As a result, it is suggested that sports coaches take advantage of non-linear training, especially the manipulation of task constraints in their training.
