When does delayed-onset muscle soreness (DOMS) typically reach its peak?

Delayed-onset muscle soreness (DOMS) typically reaches its peak 24 to 48 hours after exercise due to the physiological processes that occur in the muscle following unfamiliar or intense physical activities. After the exercise, micro-tears develop in the muscle fibers, leading to inflammation as the body begins the repair process. This inflammation contributes to the sensation of soreness and stiffness that athletes experience.

The peak soreness within this timeframe is tied to the body's inflammatory response, which takes time to develop fully after the initial muscle strain or damage. Although muscle strain and some discomfort can occur immediately after exercise, the significant soreness associated with DOMS appears later as the muscles react to the injury and begin to heal. Therefore, understanding this timing is crucial for athletes and trainers as it informs effective recovery strategies and training adjustments.
