|Deterioration of eccentric hamstring strength at the start of the second half and towards the end of a game|
Eccentric hamstring peak torque measured in 10 professional soccer players was observed to decrease after the half-time interval and progressively during a match.
According to epidemiological studies this may indicate a greater risk of muscular strain injury and impaired joint stability. The degree of hamstring force reduction was related to the isokinetic test speed, suggesting that players are more susceptible to injuries during explosive movements.
Recommendations: The author advises that coaches should ensure that the players are sufficiently warmed up before the start of the second half and that eccentric hamstring strength in players is well developed and resistant to fatigue”. Moreover, additional training of the hamstring muscles may be implied in soccer, especially for players with a low hamstring force in relation to quadriceps force (H/Q ratio).
