What Affects Energy Metabolism? Factors that affect energy metabolism are:

1: Muscle activity.

2: Ambient temperature.

3: The special dynamic role of food.

4: Mental activity.

The factors affecting energy metabolism are divided into general physiological factors and physiological activity factors, and general physiological factors include age, gender, and sleep. Physiological activity factors include muscle activity, environmental temperature, the motility effect of food, and mental activity.

The release, transfer, storage and utilization of energy that accompanies the human body in the process of material metabolism is called energy metabolism.

A person's energy demand stems from the energy demand consumed, and basal energy metabolism (BEE) determines the most basic energy requirement of the human body.

The measurement methods of energy metabolism include: self-report method, motion sensor method, heart rate detection method, direct calorimetry method, indirect calorimetry method, double standard water method, etc.

Muscle activity, mental activity, the special dynamic effects of food, and ambient temperature are factors that affect energy metabolism.

1.Muscle activity: It has the most significant effect on energy metabolism. It is mainly used to increase the oxygen consumption of muscles and do external work, so that the energy metabolism rate increases.

3.The special kinetic effect of food: The effect of the body that can produce extra calories for a period of time after eating is called the special kinetic effect of food. It is the strongest in protein, followed by fat, and least in sugar.

4.Ambient temperature: It is most stable in an environment of 20 to 30 ° C in a quiet state. Ambient temperature is too low to increase muscle tension and energy metabolism. If the ambient temperature is too high, the metabolism of substances in the body can be strengthened, and the energy metabolism will also be increased.

The main factors that affect energy metabolism are: muscle activity, mental activity, the special dynamic effect of food, and ambient temperature.

Energy metabolism determines the most basic energy needs of the human body, and it plays a series of important roles in the survival of life, such as cell function and protein synthesis in the body. It accounts for 60%-75% of daily energy needs. The BEE is more stable than DIT and PAEE, with little variation from day to day, and it is an important indicator to distinguish the energy needs of different people.

Basal energy metabolism is calculated from the basal energy metabolic rate, which is the body's basal energy expenditure per minute. Energy metabolism rate in a neutral and mild environment (20-25 ° C), waking up in the morning, the body is in a state of digestion and absorption, breathing normally and completely relaxed (lying flat, without any external muscle movement) when the body expends energy per minute.

Energy utilization

More than 50% of the energy released by various energy substances in the body is rapidly converted into the form of heat energy, which is mainly used to maintain the body's body temperature. Heat energy can then be converted into other forms of energy and hence cannot be used to do work. The remaining less than 50% of the energy is "free energy" that can be used to do work.

The carrier of this part of the free energy is adenosine triphosphate.

The energy is stored in the high-energy phosphate bonds of ATP. In the process of energy conversion of the body, ATP is not only an important energy storage substance, but also a direct energy supply substance. When the body's tissue cells carry out various functional activities, the direct energy is the reserve energy in ATP.
