TABLE 20. Basal heat-production of boys and girls per 24 hours 

 predicted from body-weight. 



This table gives the basal heat-production of boys and girls for 24 

 hours as predicted from body-weight without clothing. The values 

 represent points on probable curves drawn through extended series 

 of determinations for which heat has been computed from the 

 respiratory exchange and referred to body-weight. The table is 

 from Benedict and Talbot, Carnegie Institution of Washington, 

 publication 302, 1921, table 36, page 206. 



TABLE 21. Basal heat-production per kilogram per 24 hours pre- 

 dicted from age, for girls from 12 to 17 years of age. 



The table is from Benedict, Hendry, and Baker, Proceedings 

 National Academy of Sciences, 1921, 7, No. 1. 



TABLE 22. Formula for predicting basal heat-production of males per 24 hours. 



The formula for predicting the basal heat-production of males for 

 24 hours is as follows: 



ft = 66.473 + 13.752 w + 5.003 s- 6.755 a 



h = heat-production per 24 hours, w = weight in kilograms, s = height 

 in centimeters, a = age in years. 



EXAMPLE. 



Age 21 years, weight 63.9 kilograms, height 169 centimeters. 



h = 66.473 + (13.752 X 63.9) + (5.003 X 169) - (6.755 X21) = 1723 calories. 



The formula is from Harris and Benedict, Carnegie Institution of 

 Washington, publication 279, 1919, page 190. Benedict 1 has shown 

 that it is applicable to boys back to 10 kilograms in weight. 



TABLE 23. Formula for predicting basal heat-production per 24 

 hours for women. 



The formula is: h = 655.096 +9.563w + 1.850s-4.676a. ^heat- 

 production per 24 hours, w = weight in kilograms, s = stature in 

 centimeters, and a = age in years. 



EXAMPLE. 



Age 52 years, weight 37.4 kilograms, height 155 centimeters. 



h = 655.096 + (9.563 X 37.4) + (1.850 X 155) - (4.676 X 52) = 1056 calories. 



The formula is from Harris and Benedict, Carnegie Institution of 

 Washington, publication 279, 1919, page 190. 



TABLES 24 and 25. Standard multiple-prediction tables for normal 

 basal heat-production of men per 24 hours. 



These two tables are used together for predicting the most probable 

 basal heat-production per 24 hours of a normal man when the stature 

 in centimeters, the weight in kilograms, and the age in years are
