What causes muscle soreness and stiffness? Differentiate between acute soreness and DOMS.
What will be an ideal response?
Muscle soreness and stiffness are common in individuals who (1) begin an exercise program or participate after a long layoff from exercise, (2) exercise beyond their customary intensity and duration, or (3) perform eccentric training. The acute soreness that sets in during the first few hours after exercise is related to general fatigue caused by chemical waste products that build up in the exercised muscles. The delayed-onset muscle soreness (DOMS), which appears several hours after exercise (usually 12 hours or so later) and lasts from 2 to 4 days, might be related to microtears in muscle tissue, muscle spasms that increase fluid retention and thereby stimulate the pain nerve endings, and overstretching or tearing of connective tissue in and around muscles and joints.
