Is the connective tissue damage hypothesis related to DOMS?

The connective tissue damage hypothesis is indeed closely related to Delayed Onset Muscle Soreness (DOMS) and is considered one of the leading explanations for the phenomenon. This hypothesis suggests that microtears occur in the connective tissues surrounding muscles—such as tendons and fascia—during intense or unfamiliar exercise, particularly those involving eccentric contractions.

These microtears trigger an inflammatory response, which leads to the sensation of soreness experienced typically one to two days after the exercise. This aligns with the typical onset and duration of DOMS. Understanding this connection can help trainers develop appropriate recovery protocols for their clients, fostering better recovery from exercise and reducing the likelihood of injury.

Conversely, DOMS can also arise from factors such as muscle damage and inflammation, making the connective tissue damage hypothesis a key aspect of the broader understanding of why soreness occurs post-exercise. Recognizing this relationship is beneficial for personal trainers in creating effective and safe exercise programs for individuals, ultimately helping clients manage their training loads effectively.
