metabolic rate

Thân thiện

A scientist measures the metabolic rate of a small mouse in a laboratory.

Definition

Noun: - The rate at which an organism's body uses energy: Metabolic rate refers to the speed of the body's metabolic processes, measured as the amount of energy expended over a specific period. It represents how quickly calories are burned to sustain basic life functions and physical activity.

Usage

Metabolic rate is a scientific term used primarily in biology, physiology, nutrition, and medicine. It is often discussed in contexts related to health, weight management, fitness, and comparative animal biology. - It is typically quantified in units of energy per time, such as kilocalories per day or joules per second. - It can be modified by adjectives like basal, resting, or total to specify the conditions of measurement.

Examples

• Noun:
  • A high metabolic rate helps some people stay thin without much effort.
  • Scientists measured the animal's metabolic rate to understand its energy needs in hibernation.
  • Age, muscle mass, and genetics can all influence a person's metabolic rate.

Advanced Usage

• "Basal metabolic rate (BMR)": The rate of energy expenditure while at complete rest in a neutrally temperate environment, representing the energy needed for basic physiological functions like breathing and circulation.
  • His basal metabolic rate was calculated to be 1,600 calories per day.
• "Resting metabolic rate (RMR)": Similar to BMR but measured under less strict conditions, often used interchangeably in general contexts.
  • Even when sedentary, your resting metabolic rate accounts for most of the calories you burn.

Variants and Related Words

• Metabolism (n): The complete set of life-sustaining chemical reactions in organisms, of which the metabolic rate is a measure.
  • Exercise can boost your metabolism.
• Metabolic (adj): Relating to metabolism.
  • The doctor ordered tests to check for metabolic disorders.

Synonyms

• Energy expenditure rate: A more descriptive synonym.
• Caloric burn rate: A less formal term used in fitness contexts.

Related Phrases

• To boost/raise one's metabolic rate: To increase the speed of energy use.
  • Strength training is known to boost your metabolic rate.
• To have a slow/fast metabolic rate: Describing the relative speed of one's metabolism.
  • She seems to have a fast metabolic rate, as she eats a lot but doesn't gain weight.
