It has been shown that restraining collagenous tissue from contraction during heating influences elasticity and final yield strain but has little effect on tensile yield strength or relative yield length. The tension developed in collagenous tissue from old animals heated at temperatures above 60°C was linearly dependent on temperature. The tension developed during heating of collagenous tissue from young animals reached a peak and then rapidly declined. The temperature at which the peak occurred was dependent on both restrained length and animal age. The loss of tension was greater when the amount the samples were allowed to contract during heating was increased.
