The document discusses basal metabolic rate (BMR), which is the minimum caloric energy needed per day to sustain vital body functions. It provides two simple formulas to estimate BMR - one for men estimating 1 calorie per kg of body weight per hour, and for women estimating 0.9 calories per kg of body weight per hour. More accurate formulas factor in additional variables like height, weight, age, and gender. METS (metabolic equivalents) are also discussed as a measure of exercise intensity based on oxygen consumption.

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.
