During both professional and amateur sports activities, the musculo-skeletal system is subjected to very high biomechanical demands and often runs into injuries. This risk could be much higher if motor asymmetries are present. This study aims at gaining more insight about the presence of motor asymmetries and their relationships with potential injury. Subject of the study was a population of young athletes performing VJ. The VJ test was chosen because it is a symmetric motor task and it is commonly adopted to evaluate athletic ability in performing explosive movements. Although the subjects were healthy at the time of the experiments, all of them presented at least an asymmetry in one of the 16 selected parameters. Global parameters, which give information on the final output of the movement, do not seem to be able to reflect anomalies at joints or at coordinative level. Furthermore interesting clues of relations with past injuries and competition performances were found.

Abstract

During both professional and amateur sports activities, the musculo-skeletal system is subjected to very high biomechanical demands and often runs into injuries. This risk could be much higher if motor asymmetries are present. This study aims at gaining more insight about the presence of motor asymmetries and their relationships with potential injury. Subject of the study was a population of young athletes performing VJ. The VJ test was chosen because it is a symmetric motor task and it is commonly adopted to evaluate athletic ability in performing explosive movements. Although the subjects were healthy at the time of the experiments, all of them presented at least an asymmetry in one of the 16 selected parameters. Global parameters, which give information on the final output of the movement, do not seem to be able to reflect anomalies at joints or at coordinative level. Furthermore interesting clues of relations with past injuries and competition performances were found.
