Overview

Observational analysis shows external load affects tendon lengthening and shortening in men, indicating its role in jump performance.

Key Points

  • Tendon dynamics significantly enhance performance in stretch-shortening exercises, particularly in jumps.
  • During concentric phase, tendon shortening velocity correlated with angular velocity and power across varying load conditions.
  • Eccentric phase increases in tendon length were closely linked with mean power during the concentric phase.
  • The study involved 15 men performing jumps under different load conditions to measure muscle dynamics.
