What is metabolic rate determined by?
The amount of kilojoules your body burns at any given time is affected by your metabolism. Your metabolic rate is influenced by many factors – including age gender muscle-to-fat ratio amount of physical activity and hormone function.
What is the most important factor affecting the metabolic rate?
The most important factor affecting the metabolic rate is the intensity or speed of the exercise. The MET is a unit that represents multiples of the thermal energy expenditure rate.
How do I determine my base metabolic rate?
Calculate Basal Metabolic Rate
Your basal metabolism rate is produced through the following basal metablic rate formula: Men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years) Women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)
What is meant by a metabolic rate?
An organism’s metabolic rate is the amount of energy expended by that organism in a given time period – usually daily. At rest meaning in periods of inactivity the metabolic rate is known as the basal metabolic rate (BMR).
What does the metabolic rate measure quizlet?
Metabolic rate is the rate at which an animal converts chemical energy to heat and work (consumes). It is the energy metabolism per unit time.
How does indirect calorimetry measure metabolic rate?
Indirect calorimetry is the method by which measurements of respiratory gas exchange (oxygen consumption V O 2 and carbon dioxide production V CO 2 ) are used to estimate the type and amount of substrate oxidized and the amount of energy produced by biological oxidation.
Which tissue is most important for determining metabolic rate?
Skeletal muscle is a crucial tissue for maintaining blood glucose control and energy balance. Muscle uses both glucose and fatty acids as fuel and serves as a source of amino acids for fuel utilization by other tissues during starvation.
What factors affect the BMR and why discuss 3 factors?
- Gender: Men have a greater muscle mass and a lower body fat percentage. Thus men have a higher basal metabolic rate than women. …
- Weight: The heavier the weight the higher the BMR ex. …
- Body fat percentage: The lower the body fat percentage the higher the BMR.
What factor does not affect metabolism?
Age and gender are the factors affecting metabolism that you cannot control.
What are some factors that decrease metabolism?

- Not getting enough high-quality sleep. …
- Drinking sugary beverages. …
- A lack of strength training.
How can you increase your metabolism rate?

How can I measure my metabolism?
- Men: BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years)
- Women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)
What is a good resting metabolic rate?
What is an increased metabolic rate?
If your metabolism is “high” (or fast) you will burn more calories at rest and during activity. A high metabolism means you’ll need to take in more calories to maintain your weight. That’s one reason why some people can eat more than others without gaining weight.
What affects basal metabolic rate quizlet?
Gender and weight can affect basal metabolic rates. Basal metabolic rate is dependent upon age and genetics.
What is standardized metabolic rate?
Standard metabolic rate (SMR) is a direct measure of organism respiration (i.e. whole-body maintenance metabolism). … As an integrated measure of resting metabolic activity SMR represents the summation of many background metabolic processes that consume oxygen (Darveau et al.
What increases the metabolic rate quizlet?
Body Temp: -Higher body temp=higher metabolic rate. Ingestion of food: -raises metabolic rate 10-20% due to energy “costs” of digesting absorbing and storing nutrients.
What is basic metabolic rate quizlet?
What is your basal metabolic rate? the rate at which you use energy when your body is at rest. A feeling of physical discomfort that is caused by your body’s need for nutrients is called. hunger. Generally more calories are needed by people who.
Which of the following is a measure of metabolic fitness?
One measurement of metabolic fitness is basal metabolic rate or BMR which is a measurement of the amount of energy required for the body to maintain its basic functions while at rest i.e. breathing heart beats liver and kidney function and so on.
What is calorimetry testing?
What factors can affect the accuracy of metabolic cart studies?
- Size.
- Gender.
- Age.
- Work of breathing (2 – 3 %)
- Diet-induced thermogenesis.
- Sleep.
- Illness.
- Starvation.
What factors affect indirect calorimetry?
Factors affecting REE include:
age • gender • body weight • body composition • weight loss • medications • exercise fever • disease • infection.
Why is oxygen uptake a measure of metabolic rate?
Oxygen consumption and carbon dioxide production are used as an indirect measure of metabolic rate. This works because oxygen is used to break down food during cellular respiration whilst water carbon dioxide and energy are produced. … Metabolism refers to chemical processes going on inside cells all the time.
What controls basal metabolic rate?
The basal metabolic rate of the body is controlled by the hormones T3 and T4 produced by the thyroid gland in response to the thyroid stimulating hormone (TSH) produced by the anterior pituitary.
What are the factors that affects drug metabolism?
Physiological factors that can influence drug metabolism include age individual variation (e.g. pharmacogenetics) enterohepatic circulation nutrition intestinal flora or sex differences. In general drugs are metabolized more slowly in fetal neonatal and elderly humans and animals than in adults.
What factors can increase or decrease BMR?
Factor that can increase or decrease BMR are gender hormones body size body composition and age. Gender can affect BMR because women process more body fat and less muscle mass than men of a similar size. Hypothyroidism is most common in women and hormones have a severe impact on this.
What are some examples of metabolic processes in cells?
The processes of making and breaking down glucose molecules are both examples of metabolic pathways. A metabolic pathway is a series of connected chemical reactions that feed one another.
How do you stop a fast metabolism?
Eat healthy foods: lots of fiber and lots of fruits and vegetables. Stay away from saturated fats and simple carbohydrates such as processed or refined sugars. Eat lean proteins. Space out your calories throughout the day with smaller meals and healthy snacks so your body will consume more energy.
What causes fast metabolism?
Body size age gender and genes all play a role in the speed of your metabolism. Muscle cells require more energy to maintain than fat cells so people with more muscle than fat tend to have a faster metabolism. As we get older we tend to gain fat and lose muscle.
What are the 3 metabolic types?
There are three basic metabolism types: ectomorph mesomorph and endomorph – definitely words you probably don’t use in your normal day-to-day conversations. But learning the types of body you were born with will help your fitness plan in the long run.
What foods decrease metabolism?
