[The evaluation of serum creatine phosphokinase for estimation of energy expenditure in human subjects].
We investigated the relationship between serum creatine phosphokinase (CPK) activity and energy expenditure in young adults and evaluated whether serum CPK activity is a useful index of energy expenditure. These data were obtained from 225 (men: 94, women: 131) healthy young adults. The results of the survey were as follows: In men, there was a statistically significant correlation between serum CPK activity and energy expenditure (r = 0.370; p less than 0.01; y = 1986.0 + 8.2x), energy expenditure/body weight (r = 0.270; p less than 0.01 y = 35.4 + 0.06x) and daily activity index (r = 0.357; p less than 0.01; y = 0.38 + 0.0030x) In women, there was a statistically significant correlation between serum CPK activity and energy expenditure (r = 0.207; p less than 0.05; y = 1895.0 + 3.0x), and daily activity index (r = 0.194; p less than 0.05; y = 0.432 + 0.0017x). The higher the proportion of exercising subjects, the higher was the serum CPK activity. These results suggest that measurement of serum CPK activity can be used to evaluate energy expenditure.
