Basal metabolic rate (BMR) refers to the _____.
A
maximum rate of energy expenditure during exercise
B
energy used to digest and absorb food
C
total energy expended during physical activity
D
minimum amount of energy required by the body to maintain vital functions at rest
Verified step by step guidance1
Understand the concept of Basal Metabolic Rate (BMR): BMR refers to the minimum amount of energy required by the body to maintain vital functions at rest, such as breathing, circulation, and cellular processes.
Eliminate incorrect options: Review each option provided in the problem and determine why it does not align with the definition of BMR. For example, 'maximum rate of energy expenditure during exercise' refers to energy used during physical activity, not at rest.
Clarify the distinction between BMR and other energy expenditures: BMR is different from the energy used to digest and absorb food (known as the thermic effect of food) and the total energy expended during physical activity (which includes exercise and movement).
Relate BMR to physiological processes: Highlight that BMR supports essential functions like maintaining body temperature, heart rate, and brain activity, which are necessary for survival even when the body is at rest.
Conclude with the correct definition: Reinforce that BMR is the minimum energy required to sustain life at rest, ensuring the student understands the concept clearly.
