1. Basal Metabolic Rate – The rate at which the body uses energy
for maintenance activities, e.g. thermoregulating, activities of major organs
Simple estimation:
Men – 1 calorie x kg of body weight x hour
Women – 0.9 calorie x kg of body weight x hour
Man weighing 84 kg for a days requirements?
More complicated but accurate…
Men = BMR = 66 + (13.7 x wt. in kg) + (5 x ht in cm) – (6.8 x age in
years)
Women = BMR = 655 + (9.6 x wt. in kg) + (1.8 x ht in cm) – (4.7 x
age in years)
Man weighing 84kg, 180cm and 40?
METS… Uses oxygen consumption per unit of body weight to estimate
exercise intensity
BMR x activity factor Complete rest (sitting quietly) equates to 1 MET. This is 3.5ml O2
= calories required per per kg of body weight per minute
day 2 METS indicates the energy expended is twice that at rest etc.
They are often thought to overestimate energy expenditure.
