(A) Mechanical strain of tendons from loaded versus unloaded limbs by age group at the inflection point. (B) Mechanical strain of tendons from loaded versus unloaded limbs by age group at the failure point. (C) Normalized mechanical strain for old and young tendons at the inflection point. Each loaded tendon is normalized to its unloaded control. (D) Normalized mechanical strain for old and young tendons at the failure point. Each loaded tendon is normalized to its unloaded control. Data is depicted as mean values ± standard error. Different letters denote significance at the 0.05 level.
