Positional tendons are stiffer, have lower GAG content, and a lower risk of injury than energy storage tendons.

Energy storage tendons have higher GAG content and lower injury risk compared to positional tendons.

Positional tendons, such as the Achilles tendon, are more compliant and at higher risk of injury.

Energy storage tendons are stiffer and have lower glycosaminoglycan (GAG) content than positional tendons.
