In the process of exercise, the active muscles must be supported by energy, which mainly comes from fat and sugar. Short-term strenuous exercise makes people temporarily in a state of hypoxia, decomposes a lot of sugar in the body, and thus produces energy for muscles. This kind of exercise is called anaerobic exercise. But anaerobic exercise only breaks down sugar and does not consume fat.

After long-term exercise, the decomposed sugar in the body can't meet the needs of muscles at all, and it must be supplied by oxygen. At this time, the fat in the body begins to oxidize and decompose to generate heat. This is called aerobic exercise, which can help break down fat.

In addition, the endocrine system and nerve function in the body play the role of regulation and decomposition, so long as they are in a balanced state, they can maintain normal weight. When the regulatory function is impaired, it will disturb the balanced metabolism.

When synthesis exceeds decomposition, people will eat too much fat and store it. Only by strengthening exercise can they improve the endocrine system and nervous system, restore balance, speed up metabolism, prevent fat accumulation, and finally achieve the effect of slimming.

Precautions for sports:

1, exercise should not be too strenuous: due to the reduction of joint range of motion and the weakening of flexibility in autumn, strenuous exercise is not suitable. Anaerobic exercise and some high-intensity strength training are easy to cause physical discomfort, so it is recommended to give priority to endurance aerobic exercise in autumn.

2, fasting is not suitable for morning exercise: exercise needs to consume energy, but when you wake up in the morning, the human body does not store much energy, so you need to eat. If you don't eat in time and exercise on an empty stomach for a long time, it will lead to insufficient glycogen storage and a large amount of blood sugar consumption, leading to hypoglycemia, and then dizziness, palpitation, black eyes and other symptoms.

3. control your diet after exercise: people generally feel hungry after exercise, but if you can't control yourself and eat a lot, all your efforts will be in vain. But if you really want to eat, you can choose fruits or vegetables.
