Tendon

Tendon — Tough connective tissue that attaches muscle to bone. Tendons store and release elastic energy during running and jumping—essential for HYROX® performance.
What a tendon is
A tendon is connective tissue that transmits force between muscle and bone and contributes to storing and returning elastic energy. Structure, vascularity and mechanical role differ by tendon and region; one fixed composition percentage or healing timeline does not describe every tendon.

Adaptation and symptoms
Mechanical loading can change tendon stiffness, material properties and cross-sectional area over weeks or months, but responses vary by tendon, strain, intervention and population. Progress load gradually. Pain is not a direct measure of tissue damage; persistent, acute or worsening symptoms require qualified assessment rather than a generic programme.
