The Positive Influence of Muscle Stiffness & Performance in Elite Sport - 4 Researched Conclusions


There have been a lot of well-researched studies on the link between muscle stiffness and performance.





  1. Dynamic and explosive performance can benefit from increased muscle and tendon stiffness.

  2. When the degree of tightness is great, more elastic energy may be stored (think of it like a rubber band)

  3. Muscle and tendon tension results in an increase in peak force output, which in turn increases velocity and strength (power movements).

  4. Muscle & tendon tension improves running speed, vertical leap, and movement efficiency, making it a vital trait for success in most high-level sporting settings.
