Jumping motor tasks in people with motor control defects are probably associated with incomplete movement patterns, which can be related to non-collision injuries of the lower limbs. Therefore, the aim of the present study is to investigate the eight-week training program of feedback on the biomechanical variables of athletes with selected motor control defects in landing jump tasks.
The present study is a randomized clinical trial study before and after the intervention. 34 male recreational athletes with movement control defects were selected based on the study criteria and then randomly assigned to control and feedback groups. To analyze the data, two-way analysis of variance and Bonferroni statistical tests were used for each movement task at a significance level of P < 0.05.
The results of the study indicated an increase in the electrical activity of the VM and GM muscles in different phases of jumping in the feedback group. Also, the feedback group showed a decrease in knee valgus angle in the frontal plane (P < 0.05).
The results of the present study showed that feedback can be used to correct incomplete movement patterns in jump-landing tasks.
