Participation of the agonist and antagonist knee extensor muscles in drop kick placing kick and up and under kick in rugby athletes

摘要

Introduction: Rugby is a sport that implies constant physical contact, therefore it represents a high rate of injury risk, considering that the hip injury represents an average of 109 days without training per season [1]. The quadriceps femoris of the shooting lower limb is the muscle with the highest injury rate, being the exact moment of impact with the ball the main mechanism [2]. The point of this study is to verify the muscular participation in the exact moment of impact, in the three different types of kick, in order to allow the development of a prevention program for muscular injury in a rugby player.
