Un côté plus fort que l’autre ?
J’ai souvent la question en formation sur la différence ‘tolérable’ entre la force du côté droit et du côté gauche. Il est de mon expérience de terrain que 5 à 10% est une bonne base de travail. Cette étude est dans la même veine.

Voilà l’extrait à retenir :
“There is no specific magnitude of asymmetry that has been identified in the literature as a definite threshold separating injured and noninjured players or the potential for injury. However, it would seem magnitudes of 15% or more are often associated with players who have recently sustained an injury, whereas magnitudes below 10% are typically reported in noninjured populations. Therefore, an asymmetry threshold of 10-15% or more is thought to place additional strain on the weaker leg, compromising the player’s performance and predisposing the athlete to various injuries.”
Et vous qu’en pensez-vous ?
