Abstract
Anterior cruciate ligament (ACL) injury prevention should remain a top priority, because of the high costs, social expenditures and the harmful effects on a person’s talent development and quality of life. Because the risk of ACL injury decreases with lower knee loading, we aim to identify the effect of visual instruction and feedback interventions on joint loads. Moreover, we examined the effect of visual instruction and feedback on intrinsic motivation. Twentyfour young talented football players participated. They were divided into a control group, instruction group and instruction + visual feedback group. Every group participated in a 6-week program that consisted of a pretest, training weeks one to four (T1-T4), a post-test and retention test. Lower-limb joint kinematics were collected through wearable reflective markers (Vicon) during sidestep cutting. Two digital cameras provided the option for visual feedback and in between the exercises, a composed intrinsic motivation inventory was filled out. The data was analyzed with the use of repeated measures ANOVA. A main effect of time on joint loads was found: scores at the pretest were better than at the post-test and retention test . Furthermore, a main effect of time on intrinsic motivation was found: scores at T3 were significantly higher than at T1. This study provided insight into how intrinsic motivation and joint load scores change over time, regardless of intervention group. Future research should focus on making this research more transferable to the field to increase ecological validity.
