Its not all about sprinting: mechanisms of acute hamstring strain injuries in professional male rugby union—a systematic visual video analysis

Review written by Dr Jarred Boyd info

Key Points

  1. Hamstring strain injuries, in professional Rugby Union, are influenced by multiplanar trunk kinematics, which may be a relevant moderator during the rehabilitation process.

BACKGROUND & OBJECTIVE

Field sport athletes are exposed to frequent bouts of high intensity biomechanical demands, particularly with a tactical intent of invasion and evasion. One of the more common tissues subjected to these high demands is the hamstring complex due to the constant stress-strain loads. Categorization of hamstring strain injuries has been postulated to be either stretch-type or sprint-type injuries (1).

The aim of this study was to perform video analysis and determine the most probable biomechanisms of hamstring strain injuries in Rugby Union athletes.

Field sport athletes are exposed to frequent bouts of high intensity biomechanical demands, particularly within the hamstring complex.

Implementation of isolated loading in addition to integrated trunk coordination appears to be a more holistic pursuit in expanding the kinetic and kinematic boundaries of athletes returning from hamstring injuries.

METHODS

  • This study was a systematic visual video analysis of Leinster Rugby Union athletes who sustained a hamstring strain injury during the 2015-2016 and 2016-2017 seasons.
