basal metabolic rate

(noun)

The amount of energy expended while at rest in a neutrally temperate environment, in the post-absorptive state.

Examples of basal metabolic rate in the following topics:

  • Humans: Work, Energy, and Power

    • The rate at which the body uses food energy to sustain life and to do different activities is called the metabolic rate.
    • The total energy conversion rate of a person at rest is called the basal metabolic rate (BMR) and is divided among various systems in the body.
    • Identify what factors play a role in basal metabolic rate (BMR)

  • Human Metabolism

    • Your basal metabolic rate is the rate at which food is converted into heat transfer and work done while the body is at complete rest.
    • The body adjusts its basal metabolic rate to compensate (partially) for over-eating or under-eating.
    • The body will decrease the metabolic rate rather than eliminate its own fat to replace lost food intake.
    • You will become more easily chilled and feel less energetic as a result of the lower metabolic rate, and you will not lose weight as fast as before.
    • Exercise helps with weight loss because it produces both heat transfer from your body and work, and raises your metabolic rate even when you are at rest.

  • Blood Flow

    • The cardiovascular system, which consists of blood vessels and the heart, helps to distribute nutrients, O2, and other products of metabolism.
    • The major quantity of interest in describing the motion of blood particles is velocity—the rate of change of the position of an object with time:
    • Another important parameter is the acceleration—the rate of change of velocity: $a = \frac{\Delta v}{\Delta t}$
    • Normal plasma behaves like a Newtonian fluid at rates of shear.

  • Thermal Pollution

    • An increased metabolic rate may result in fewer resources; the more adapted organisms moving in may have an advantage over organisms that are not used to the warmer temperature.
