What are the mechanisms by which overuse may affect connective tissues?
What will be an ideal response?

Sustained loads on tendons, ligaments, or cartilage can lead to excessive deformation (plasticity) and threat of failure. Repetitive loading may reimpose a load before a tissue has returned to its initial state, thus increasing the likelihood of exceeding the yield point (elastic limit), resulting in inflammation and microfailure.
