Abstract: | The objectives of this work here focus on the differences in responses to multiple cyclic tests of different sections along
the length of the same tendon. Tendon specimens were obtained from the hindlimbs of canines and frozen to -70°C. After thawing,
specimens were mounted in the immersion bath at room temperature (22°C). preloaded to 0.13 N and then subjected to 3% or 4%
of the initial length at a strain rate of 5%/sec. It was found that different sections of the same long tendons had different
resistances to deformation. In general, the bone end sections were stiffer and carried greater loads for a given strain than
the muscle end sections, and the mid-portions were the least stiff and carried the smallest loads for a given strain. The
results of this study offer new information about the mechanical responses of collagenous tissues. We know more about their
responses to multiple cyclic extensions and how their responses are different from the positions along the length of the tendon
specimen. The nature and causes of these differences in the stiffness are not fully known. However, it is clear that differences
in the mechanical response of tendons and other connective tissues are significant to musculoskeletal performance. |
