Sex difference in SME IL-6 protein content and ACTH response to stress. (A) Immunoblot analysis showing lesser SME IL-6 protein content in males compared to females (*P < 0.001; n ≥ 5). (B) Females display increased ACTH at all speeds versus pre-exercise (P < 0.05) and compared to males (P < 0.05; n ≥ 6). Results displayed as individual data points at corresponding speeds. There was no sex difference in ACTH concentration prior to initiation of exercise (Pre). (C) There was a significant sex difference in the cortisol response to exercise (*P < 0.05) and only females demonstrated a significant increase in cortisol during exercise (‡P < 0.05, vs. Pre). There was no increase in ACTH or cortisol in males in response to exercise. F, female; M, male.
