The decrease in basal metabolism with age during the period 

 of adult life has been shown to be well represented by the linear 

 equations. 



For men (N = 136), 



h = 1823.80-7.15 a, /ifc = 28. 703-0. 112 a, h = 1022.17-3.60 a. 

 For women (2V = 103), 



fc = 1420.47-2.29 a, hk = 28.308-0.124 a, h = 924.25-2.96 a. 



FIG. 5. DECREASE IN METABOLISM WITH AGB IN MEN AND WOMEN. Fig. A shows 

 the decrease In total daily heat production, B, the decrease in calories per kilogram of 

 body weight and 0, the decrease in calories per square meter of body surface. The 

 straight lines are due to the equations given in the text.
