When they are crimp it is believed to help with muscle loading forces at the tendo-perosteal junction and the Musculotendinous junction. When exercising the crimp flattens and then stress is felt along the length of the ligament or tendon. The bodies physiological range of ligaments or tendons under strain is between
3 and 40 of its initial length this is due to the flattening of the crimp.When physical activity continues with no excessive or sudden impact or strain placed upon the structures then tolerances up to 100 will be allowed by the body and this will have no irreversible macroscopic or molecular damage to the tissue but if the loading is excessive or sudden then its more likely damage is likely will occur. This kind of damage to the ligament or tendon is irreversible and there is a noticeable partial rupture of the cross links in the fibres and if the loading continues then more fibres will
