Values are means ±s.e.m. Blood was drawn before exercise (Pre), after 0.5 h (0.5 h ex), 1 h (1 h ex), 1.5 h (1.5 h ex), 2 h (2 h ex) and 3 h (3 h ex) of two-legged kicking exercise at 60 % of the resistance which could be sustained for 2 min and 1 h (1 h rec) and 2 h (2 h rec) after the end of exercise. For plasma data n = 6 except at 3 h of exercise where n = 4 and for RER n = 3–6.
