The MLG-R muscle injury classification for hamstrings. Examples and guidelines for its use


Muscle injuries are very common in sport. In soccer, the most popular sport in the world, the majority of muscle injuries are located in the lower extremity (92–97%); hamstrings (28–37%), quadriceps (19–32%), adductors (19–23%), and calf muscles (12–13%), all of them are biarticular muscles, with a complex architecture and containing a high proportion of fast-twitch fibers.

Football teams have important budgets and spend great amounts of money to win titles; it has been proved that injuries had a significant influence on performance in male professional football, but muscle injuries seem to keep growing. The reason to this is multivariable: there is no consensus regarding hamstring muscle injuries (HMIs) return to play (RTP) criteria in the literature, the time for recovery is highly variable, the increased physical demands during games, or the influence of congested period of games on players health.
