Energy consumption during exercise

There are two main applications when exercising: one is to convert energy substances in the body through muscle contraction into exercise energy; the other is to turn energy substances into thermal energy through various pathways, maintain body temperature and sweating.

When the human body moves, the energy consumption and the size of the exercise, the time and environmental factors have a close relationship. In general, the larger the exercise strength, the longer the exercise time, the greater the energy consumed, and this situation is clearly related. That is, when the intensity intensity is certain, the exercise time is increased to 2 times, and the energy consumed is 2 times the original. The effects of environmental factors on energy consumption are also relatively large, but there are very few people. In general, the human body is most stable in an environment of 20 to 30 ° C, and the energy consumption is also least. When the temperature is less than 20 ° C or higher than 30 ° C, the metabolic rate of the body will increase, and the energy consumption will also increase accordingly. This increase has no significant linear law, but the overall trend is in line with law.

The intensity of the movement representative of different movements is different, so the energy consumed by different forms of movements also has a large difference. In all forms of motion, swimming is a movement of the most energy consumption. In the process of continuous advancement of the resistance of the body overcoming water, the limbs are in a large amount of energy supplied with nutrients.

In motion, the order of consumption of several nutrients is different. The consumption of exercise in the pre-glucose is main, supplemented by protein, and is rarely involved. Sports in the middle of the exercise, the sigma stored in the body is basically exhausted, and fat begins to mobilize and decompose energy. In order to achieve the effect of exercise, each exercise time and exercise must reach a certain minimum standard, otherwise it will not reach the purpose of reducing fat.
