Equations of ten Haaf and Weijs for Predicting Resting Energy Expenditure for a Young Adult Who Engages in Recreational Athletics

Patient selection: recreational athlete from 18 to 35 years of age

Parameters:

(1) body weight in kilograms

(2) fat-free mass in kilograms

(3) height in meters

(4) age in years

(5) sex (0 if female, 1 if male)

REE in kcal per day =

= (11.936 * (weight)) + (587.728 * (height)) - (8.129 * (age)) + (191.027 * (points for sex)) +29.279

= (22.771 * (fat-free mass)) + 484.264

REE in kJ per day =

= (49.94 * (weight)) + (2459.053 * (height)) - (34.014 * (age)) + (799.257 * (points for sex)) + 122.502

= (95.272 * (fat-free mass)) + 2026.161
