Factors affecting human metabolic rate

We know that each of us is carrying out various metabolisms all the time every day. Maybe everyone doesn’t know much about this aspect. Each of us should pay more attention to our own metabolism so that we can protect our own growth. This is very helpful for our own growth. Let us take a look at the factors that affect the human body’s metabolic rate.

1. Depends on the person's activity, environmental conditions, age, gender and body weight (or body surface area)

It can be measured by the oxygen consumption per unit time of the human body. The heat generated per unit surface area of ​​the human body per unit time also reflects the rate at which the human body converts food into energy through metabolism. The unit is met.

1met=58.2W/m2.

Metabolism is a chemical heat-producing process in which food combines with oxygen to produce the energy needed by the human body. The greater the amount of human activity, the higher the metabolic rate, which is directly proportional to the oxygen consumption. Normal diet: 1L oxygen consumed by human body can produce 20.6kJ of heat. When sitting and resting, the metabolic rate is 1met and the walking speed is 0.89m/s.

It is 2met, playing basketball is 5 to 7.6met, and the metabolic rate is lowest when the human body is lying down or sleeping, which is 0.7met.

2. Living in this world is not an easy thing. You need to maintain your heartbeat, blood pressure, circulation, respiration, body temperature, and every cell in the body must be nourished. To do these things, you need to consume energy. Even if you just lie in bed and do nothing, you still need energy. This basic energy consumption is called basal metabolism. The basal metabolic rate is the amount of energy consumed by basal metabolism every day or every hour.

A high basal metabolic rate means that the body consumes more energy when at rest. For normal adults, this number should be basically stable, but will slowly decrease with age.

On the basis of the basal metabolic rate, people also have to work, live, exercise, digest and absorb, all of which will increase consumption. Total energy expenditure in a day is the basal metabolic rate plus the energy expenditure of daily life.

However, the basal metabolic rate and the energy consumption of the body for various activities are also affected by many factors.

Knowing more about the factors that affect the human body's metabolic rate is of great benefit to our body. We can all try to pay attention to it. In order to avoid causing more unnecessary harm to our body, we must eat more beneficial foods and do more physical exercise, which can greatly improve our own physical fitness.
