The term “overuse injury” is frequently used in medicine when talking about the musculoskeletal system. Repetitive stress, without adequate time to allow for healing, will lead to the breakdown of the components that make up the musculoskeletal system. This is especially true for bones and tendons. Overuse injury of bones can lead to the development of stress fractures. Similarly, overuse injuries to tendons can lead to the development of tendinitis.
