The aim of the study was to investigate the effects of a single bout of concentric exercise and a single bout of eccentric exercise inducing no or just mild muscle damage, matched for energy expenditure, on glucose, lactate, CK concentration. 8 healthy and active male participants took part in a randomized cross over trial consisting of 30minutes concentric(uphill, 16%) respectively eccentric(downhill, -16%) exercise on a treadmill. Exercise intensity was matched at 60% of HRmax. Two weeks later, the subjects completed the same protocol with the opposite exercise type. Exercise protocols had same heart rates indicating matched intensity and metabolic demands. Venous blood samples were drawn before, directly after and 3 hours after exercise. CK concentration increased significantly immediately and 30minutes after eccentric exercise compared to baseline, but concentric exercise did not induce any significant change with exercise and recovery period. Glucose concentration decreased significantly immediately after concentric exercise but not after eccentric exercise compared to baseline. Lactate concentration increased immediately after exercise then decreased 3hours after exercise, but no difference in the pattern of change was measured between concentric and eccentric exercise treatment. These results suggest that glucose metabolism immediately after exercise was lower in concentric exercise than eccentric exercise, and eccentric exercise do not necessarily relate to the changes in lactate metabolism.
