Greater post-exercise CK rise in men may indicate sex-specific muscle responses; leaves open whether this informs biomarker interpretation in active patients.
Does 2 hours of exercise affect serum creatine kinase levels differently in men compared to women?
Men exhibit a significantly greater increase in serum creatine kinase after exercise compared to women, suggesting female muscle may be less susceptible to exercise-induced damage.
Shumate et al. (1979) studied this question.
