and environments affect the storage and release of energy in tendons.

Understanding tendon mechanical properties, such as stiffness and hysteresis, can provide insights into injury mechanisms. This research addresses the inconsistency of previously reported and tendon hysteresis properties. Although limited, our preliminary findings suggest that hystereses (Mean ± SD; 55% ± 9%) are greater than hystereses (14% ± 1%) when directly comparing the same tendon for the same loading conditions in a sheep model within 24 h . Overall, it therefore appears that the tendon mechanical properties are affected by the testing environment, possibly related to differences in muscle-tendon interactions and fluid flow experienced . This communication advocates for more detailed investigations into the mechanisms resulting in the reported differences in tendon behaviour. Overall, such knowledge contributes to our understanding of tendon function towards improving modelling and clinical interventions, bridging the gap between and observations and enhancing the translational relevance of biomechanical studies.
