Elevation of creatine phosphokinase in young men after recreational exercise
M. A. LaPorta, H. W. Linde, D. L. Bruce and E. J. Fitzsimons
Twenty healthy male volunteers were divided into four groups for a period
of recreational physical exercise. Standard blood chemistry determinations
were made before exercise and on the two subsequent days. Creatine
phosphokinase (CPK), SGOT, and lactic dehydrogenase levels were transiently
elevated, but the change was considered significant only in the CPK level
after certain types of exercise. Persons having these determinations
performed should be questioned about recent physical exertion in the event
of abnormal laboratory results.
