focal tissue thickening
Excessive formation of fibrous connective tissue. In sport, overtraining can lead to muscle fibrosis, with adhesions developing between muscle fibres and cross linkages forming between muscle fascia in the overused muscles. Fibrosis may cause local pain and reduce the ability of the affected muscle to contract and relax rapidly.

fibrosis
Formation of fibrous tissue; fibroid degeneration.
- postfibrinous f. — that occurring in tissues in which fibrin has been previously deposited.
- proliferative f. — that in which the fibrous elements continue to proliferate after the original causative factor has ceased to operate.

fibrosis
(fībrō′sis)
n
n
1. the process of forming fibrous tissue, usually by degeneration (for example, fibrosis of the pulp). The process occurs normally in the formation of scar tissue to replace normal tissue lost through injury or infection. 2. an abnormal condition in which fibrous connective tissue spreads over or replaces normal smooth muscle or other normal organ tissue. Fibrosis is most common in the heart, lung, peritoneum, and kidney.

Fibrosis is the formation of excess fibrous connective tissue in an organ or tissue in a reparative or reactive process. This is as opposed to formation of fibrous tissue as a normal constituent of an organ or tissue. Scarring is confluent fibrosis that obliterates the architecture of the underlying organ or tissue.
The term is also sometimes used to describe a normal healing process,[1] but this usage is less common.
