Connective Tissue
Connective tissue is a broad group of tissues that support, bind or separate other tissues. Tendons, ligaments and cartilage differ in structure, function and blood supply.
Structure and function
Connective tissues contain cells within an extracellular matrix. Dense collagen-rich tissue forms tendons and ligaments; cartilage is a specialised avascular tissue whose cells receive nutrients by diffusion. These tissues do not share one adaptation speed, healing time or failure mechanism.

Training and recovery
Mechanical loading can change tendon stiffness, material properties and cross-sectional area, but responses vary with tissue, population and loading. Reviews do not support a universal “2–5 times slower” rule or a single weekly progression cap. Progressive loading should match current capacity and symptoms. Isometric, eccentric and other resistance methods are tools rather than universally superior prescriptions. Persistent or worsening pain, swelling, loss of function or an acute injury requires qualified assessment.

FAQ
Does connective tissue always adapt more slowly than muscle?
No universal multiplier applies across tissues, people and loading programmes.
What strengthens tendons?
Progressive mechanical loading can produce adaptation, but the appropriate mode and dose depend on the person and tissue.
