Purpose: This study examined sex differences in strength loss, muscle soreness, and serum creatine kinase (CK) and myoglobin (Mb) after high-intensity eccentric exercise of the elbow flexors in a large group of men and women. Methods: One hundred participants (58 women, 42 men) performed 50 maximal eccentric contractions of the elbow flexor muscles of their nondominant arm. Maximum isometric voluntary contraction (MVC) was recorded at baseline, immediately after exercise, and at 0.5 (12-14 h), 3, 4, 7, and 10 d after exercise. Blood samples for serum CK activity and Mb were taken at baseline and at 4, 7, and 10 d after exercise. Soreness was evaluated at baseline and at 0.5, 3, 4, 7, and 10 d after exercise. Results: Women experienced significantly greater relative strength loss immediately after exercise (-57.8% +/- 19.1) than men (-50.4% +/- 16.9%) (independent t-test; P
