Tendons act as straps in the body
The dry weight of each wall of tendons is made up of more than 95% of collagen. The ends of tendons, which are the most solid parts, are composed almost exclusively of collagen, up to 99%. Our tendons’ properties and functions are directly related to the architecture and quality of the collagen fibres.
Tendons provide an essential support in joint movement. The multiple functions of tendons include attaching muscles to bones, joining and stabilizing skeletal joints, and transmitting muscular force to bone pieces. Tendons also allow muscles to be at an optimal distance from the joint.
Therefore, tendons, together with muscles and bones, form a unique team that constantly works in synergy. The decrease of collagen with aging weakens the area where tendons are attached to the bone. This creates a more fragile area and frequently causes several injuries.
