What are the short-term effects of exercise on the musculoskeletal system muscle fiber micro tears?

Short-term effects of exercise on the musculoskeletal system include the occurrence of microtears in muscle fibers, particularly after intense or unfamiliar physical activity. These microtears lead to inflammation and temporary muscle soreness, commonly known as delayed onset muscle soreness (DOMS). In response, the body initiates a repair process that strengthens the muscle fibers, promoting growth and adaptation. This cycle of damage and repair is crucial for increasing muscle strength and endurance over time.
