What is the basal metabolic rate

summary

I believe many people understand the basic things. In our life, we all breathe and exercise. Let's talk about the basic metabolic rate.

What is the basal metabolic rate

First of all, basal metabolic rate (BMR) refers to the energy metabolic rate when the human body is awake and extremely quiet, not affected by muscle activity, environmental temperature, food and mental stress. This is the most basic metabolism when people just wake up, which is not controlled by anything, that is, the basic brain movement.

Secondly, when the human body is awake and extremely quiet, it is not affected by mental tension, muscle activity, food and environmental temperature. To determine the basal metabolic rate, we should lie down for half an hour (but keep awake) before breakfast in the morning, and maintain the room temperature above or below 20 ℃. We should use the instrument to measure it according to the indirect calorimetry. The unit of BMR is kJ / m2 / h (kJ / m2 / h), which is the number of kilojoules per square meter of body surface heat per hour.

Finally, in the same gender, weight and age group of normal people, the basal metabolic rate is very close, of which about 90% of the people's metabolic rate and the average difference is not more than 15%. Therefore, the percentage value is regarded as the limit of normal value in clinic. Beyond this threshold, it is considered as abnormal basal metabolism. In patients with hyperthyroidism, the metabolic rate was 20-20% higher than that of normal. The measurement of basal metabolic rate is a simple and effective method for clinical diagnosis of thyroid diseases.

matters needing attention

In daily life to develop good habits, and to actively participate in physical exercise, keep the body's basic sports needs, so as to keep the body healthy, and do not eat some junk food, eat more green vegetables and fruits.
