Define basal metabolic rate
Define basal metabolich rate: The calorie consumption of a person composes the basal metabolic rate and active metabolic rate.
Basal metabolic rate definition:
The basal metabolic rate identifies the amount of energy the human body needs to maintain its function every day and in the fasted state without physical effort - required at an ambient temperature of 68 ° Fahrenheit - so in complete tranquility.
Define basal metabolic rate explained
The human body burns calories in any case - even if it is in an idle state. BMR means that the body burns calories to maintain bodily functions. Also if you are not doing anything or while you sleep.
To do so the body requires a specific amount of calories. The only way to keep the primary duties of the body - function of the organs, breathing, metabolism, circulation - maintained. So if you do not eat enough, you run the risk that your body fails the service. The basal metabolic rate plays a very crucial role in the energy needs of the people. The second pillar is the use of calories what you need for your activities. The calorie used determines mainly the physical activity. In adults with easy physical activities, the basal metabolic rate reaches a value between 60 and 70 percent - as measured by the total energy required.
Define basal metabolic rate - a closer look
The calorie requirement varies: it is firstly depending on weight and size, and secondly by age and sex, and body composition. The higher the weight and size of a human being are, the higher is also the metabolically active tissue. Not only that: the body surface, which means a higher expenditure of energy to regulate body temperature rises the same time.
Gender also plays a not insignificant role: men have a higher BMR than women. The reason for this is the larger muscle mass of the so-called stronger sex. Age also result in differences in the basal metabolic rate: young people have a higher BMR than the elderly. The muscle mass decreases with age. The metabolism slows down with the final result that the metabolic rate falls in the elderly. From 30, it must be from a sinking basal metabolic rate of about three percent per decade of life. And ultimately, the body composition should never be disregarded. Generally speaking, the larger the muscle mass, the higher the BMR. The explanation is quite straightforward. The metabolism of muscle tissue is much more intense than that of the fatty tissue.
Also, someone who is involved in a dense physical activity or doing a lot of sports got a higher BMR than someone who sits at the desk and does not pursue any sporting activity.
To calculate your calorie needs and your calorie consumption, you first need to know your calorie basal metabolic rate. This basal metabolic rate depends mainly on the age, body size, weight, and sex.
