Is the connective tissue damage hypothesis one of the leading theories explaining Delayed Onset Muscle Soreness (DOMS)?

  1. True

  2. False

  3. Only for minor injuries

  4. It is not considered valid

The correct answer is: True

The connective tissue damage hypothesis is indeed one of the leading theories explaining Delayed Onset Muscle Soreness (DOMS). This hypothesis suggests that the soreness experienced after intense exercise is partly due to damage to the connective tissues surrounding the muscles, which includes tendons, ligaments, and fascia. When these tissues sustain microtrauma during strenuous physical activities, it can lead to inflammation and pain, contributing to the overall sensation of soreness that typically arises 24 to 48 hours post-exercise. Furthermore, this hypothesis is supported by research demonstrating structural damage to muscle fibers and associated connective tissues after eccentrically biased, high-intensity exercise. The inflammation that follows this damage is thought to trigger pain responses and may take time to develop, which aligns with the onset of DOMS. Understanding this hypothesis is crucial for fitness professionals as it highlights the importance of gradually progressing workout intensity to minimize potential soreness and injury in clients. Thus, recognizing the role that connective tissue plays not only leads to informed training decisions but also enhances recovery strategies for individuals experiencing DOMS.
