According to a study conducted by a team of Spanish researchers, football players display different muscle response parameters depending on the position that they hold on the pitch.
The research has been published in the 'Journal of electromyography and kinesiology'.
Scientists from the University of Vigo have analysed different muscle response parameters in 78 Spanish first division footballers who have been playing for between four and fifteen years. They found variations depending on the field position of the players.

', the results show that one of the extension muscles of the knee, rectus femoris muscle, belonging to the quadriceps muscle group, has different contraction, contraction maintenance and recovery times according to the specific position of the player on the pitch.
The authors measured the values of these times with a technique developed within the University of Ljubljana (Slovenia) named tensiomyography (TMG), which is used by various first division teams, like Barcelona Football Club.
