Strong sinews are not only helpful for injury prevention but also for sports performance. When a tendon is streched, the elastic energy is stored within this structure.
This deformation energy is recoiled and used to enhance motor output in the concentric phase of the short-shortening cycle (Zatsiorsky and Kraemer, Science and practice of strength training).
For the athlete, it transfers into a higher/ longer jump, and a more efficient stride.
