Are Appropriately Designed and Dosed Eccentrics part of your Early Treatment Plan?

Not even 25 minutes into the opening game of the 2018 World Cup, Russian midfielder Alan Dzagoev pulled his hamstring.

The prevalence of hamstring injuries during soccer match play remains high. It has been reported that sprinting-type hamstring injuries might be related to insufficient eccentric hamstring strength. Recurrent injury rates remain equally high and might be related to inadequate rehabilitation and too early return to play.

Inclusion of the Nordic hamstring exercise has showed promise in reducing occurrence rates in professional soccer players. However, due to the high torque/force requirements to perform the Nordic exercise, it is mainly used in prevention and in the later phases of rehabilitation.

With appropriate design and dosing we can introduce eccentrics early on in the rehabilitation treatment plan and therefore be more effective in preparing the tissue for its task. Appropriate design considerations include:

  • Where to place maximum external peak torque?
  • Eliminating the concentric phase
  • Open and closed chain, depending on the injury mechanism
