The Basal Metabolic Rate (BMR) Is the Minimum Energy Intake

question 30

Essay

The basal metabolic rate (BMR) is the minimum energy intake required to maintain a body that is awake and at rest. While the rate varies with age, gender, health, and body mass, a reasonable value is 1600 Cal per day. Walking can require 2.5 times the BMR, and exertion in work or sports can require 7 times the BMR. Using this information, calculate the energy expended by someone playing basketball, and determine how many minutes she could play with the energy from one jelly doughnut that has a mass of 50 g and a food value of 5 Cal/g.
