What is the level of physical activity?
The level of physical activity is a number in a formula that nutrition experts, fitness experts and doctors use how many calories a person burn a day, and therefore how much calories should eat. Scientists have used energy estimates on various activities and sorted them into categories based on intensity and frequency, from extremely inactive to extremely active. Since all three components of the formula are based on estimates, there is some space for errors. For most people, however, this is a relatively effective way to determine the amount of energy spent every day.
How much energy does a person spend for a 24 -hour period, which is charged by physical activities such as cleaning, work and exercise, is an estimated level of human activity. This can then be converted into a multiplier, which is multiplied by basal metabolic speed (BMR) to determine the estimate of Person's total energy expenditure (TEE) for one day. If basal metabolic peace and total expenditure are already knownE on energy, you will find a multiplier level of physical activity by dividing the total energy expenditure at basal metabolic speed.
Basal metabolic speed is the amount of calories that the body completely burns at rest, without digestion, movement or other participating factors. These calories are used to supply all body body systems with sufficient energy to function and keep the body alive. If you already know your total energy expenditure, you can divide them into a physical activity level to determine the basic metabolic speed.
The level of person's physical activity could be one of the five or six categories, depending on the source used, each with its own multiplier, which estimates the amount of calories burning tasks associated with the tasks associated with a hundred. A completely inactive person, such as someone who is on the bed, has a multiplier 1.2. At the opposite end of the spectrum canE have an extremely active person, such as someone who has a physically demanding work and participates in physically intense hobbies and sports, a multiplier 2.0 or even 2.4.
Total energy expenditure, the result you get by multiplying the basal metabolic speed of physical activity can help you get, lose or maintain weight. For example, if your total energy expenditure is estimated at 2,000 calories, you can make sure you eat another 500 calories, a total of 2,500 per day, if your goal was to gain weight. Likewise, you could deduct 500 calories and eat 1,500 if your goal was to lose weight.
