I investigated the mechanical properties of rabbit Achilles tendon from birth to senescence. The cross-sectional area and maximum load increased with growth and aging. These changes may be influenced by increase in body weight. Though the tensile strength of mature tendon (67MPa) was much higher than that of immature tendon (23MPa), we found no clear difference when it was compared to that of old tendon (66MPa). The average elastic modulus of mature tendon (618MPa) was higher than that of immature (281MPa) and old (530MPa) tendon. The averages of elongation at failure were approximately 16% strain for Achilles tendon from birth to senescence. These results suggest that rabbit Achilles tendon becomes much stronger and stiffer through growth, then becoming less stiff from maturity to senescence.
