Sample strain (A) and stress (B) measurements for a turkey FPPD3 tendon. Data are for a controlled isovelocity lengthening at 1 mm s⁻¹. Continuous elastic modulus (EM; C) was measured as the derivative of stress over strain. Maximum EM was determined by taking the peak of the continuous EM curve (C). Breaking stress and strain were taken at the point of maximum stress, as indicated by the dotted line.
