Fibril-level deformation of tendon fascicles. (A) Fibril strain fully recovered for all strain groups, suggesting that the collagen fibrils are undamaged. On the other hand, (B) interfibrillar sliding only partially recovered, exhibiting damage at the fibril-level. Dashed line represents when samples were unloaded and error bars represent SEM. (C), The interfibrillar sliding τ was strain independent and averaged 7.43 min, suggesting that 60-min rest was long enough for interfibrillar sliding recovery. The dashed lines represent the 95% confidence intervals.
