Basal Metabolic Measurement
Metabolic processes are extremely important as they are the key indicators of health. The way and the speed of the metabolism depends on the body’s vital energy.
What is basal metabolism
It is the basic amount of energy needed by the body to provide its own processes at rest – for digestion of food, delivery of oxygen and nutrients, blood supply and respiration. The calculation of the level of metabolism will allow you to know how much you need to get a minimum of calories for normal functioning of the body.
The value of basal metabolism is determined by a combination of genetic (internal) and external factors.
- Age: basic metabolism slows down with age. Starting from the age of 20, this figure decreases by about 2% every ten years.
- Sex: the intensity of the main exchange in men on average is 1 kcal/kg/h, that is, per day for the main exchange spent 1700 kcal for men weighing 70 kg. For women, this value is 10 % less. Men have more muscle mass and less body fat. This means that they have a larger value of the main exchange.
- Body weight
- Height to weight ratio (body surface area): The larger the total body surface area, the higher the base metabolism. Energy costs are proportional to the surface area of the body
- The structure of the body: the intensity of the basic exchange in different organs and tissues varies. As energy consumption decreases at rest, they can be arranged in this order: internal organs—muscles—adipose tissue. Muscle mass is more active than fat and its maintenance requires more energy.
