Final answer:
Delayed-onset muscle soreness (DOMS) typically occurs one to three days after exercising due to microscopic muscle fiber tears, and it subsides within a few days.
Step-by-step explanation:
The pain from delayed-onset muscle soreness (DOMS) typically occurs one to three days after exercising and usually subsides within two to three days later. While once attributed to lactic acid buildup, it is now known that the pain of DOMS is more likely caused by microscopic tears in the muscle fibers.
Such tears can result from overexerting the muscles, especially if the body hasn't been given adequate time to recover between intense workouts or if the exercises are carried out with improper form. To maintain muscle health and avoid issues like tendinitis or strains, a proper warm-up, appropriate load management, good technique, and allowing for adequate recovery time are key.
