Final answer:
Delayed-onset muscle soreness (DOMS) typically occurs 24-48 hours after strenuous exercise, resulting from microscopic muscle fiber tears, and subsides within a few days.
Step-by-step explanation:
The correct answer to when delayed-onset muscle soreness (DOMS) typically occurs after strenuous exercise is B) 24-48 hours after exercise. DOMS is the pain or discomfort felt in the muscles one to three days after engaging in physical activity that the body is not accustomed to or at an intensity that is higher than usual. This discomfort is thought to arise from microscopic tears in muscle fibers, rather than from lactic acid buildup, which clears from the muscles relatively quickly. DOMS typically subsides within a few days after its onset, and allowing adequate rest between intense exercise sessions can help in its management.
