Why did you have no appetite after running, but he was hungry after swimming?

Slow -jog and swimming are the two sports that many people like. I do n’t know if everyone feels like this. When you run around the track and field for eight laps, you are panting and feel that you do n’t want to eat anything in your stomach. And if you swim for three kilometers around the swimming pool, you will feel so hungry and panic, and you can't wait to have a few big meat buns in front of you, and quickly eat into the belly.

Since they are all aerobic exercise, they are also very tired. Why is the impact of running and swimming on appetite?

Scientists have really studied this matter.

Compared to running or cycling on land, swimming has many special advantages. It not only reduces the pressure of weight on muscles, but also uses the body's muscles to improve cardiopulmonary function. So choosing swimming is a good way to exercise.

However, if you want to lose weight, the effect of swimming is obviously better than jogging or cycling.

I do n’t believe that the runners on the sports field are often lean and thin, and swimmers, although they ca n’t reach the point where they have a large waist, are obviously much stronger than runners.

Scientists have found that after swimming, they will have a strong sense of hunger, mainly caused by water temperature.

Energy consumption when the human body is soaked in water is usually higher than on land. Especially when the water temperature is lower, the stronger the hunger. The reason is that the energy loss caused by low temperature to the human body should be greater than the energy loss caused by exercise. In other words, when you are swimming, not only will the sports bring energy loss, but the water temperature in swimming is too low, which will also cause some physical energy loss.

Scientific researchers conducted a test. After the water heating of the swimming pool, it was found that 28 degrees Celsius was a bar. When the water temperature was higher than 28 degrees Celsius, swimming the same distance, and the energy consumption was significantly reduced. Energy consumption increases significantly.

The general constant temperature swimming pool, whether it is winter or summer, the water temperature is constant at 26 degrees Celsius. Because the normal temperature of the human body is about 36 degrees Celsius, a 10 -degree temperature difference will be formed. Therefore, when everyone goes into the water, they often sit on the pool first and squeeze some water on the body to allow the body to adapt to that temperature and then get into the water.

But even so, when people just got the water, they still felt very cool. They had to be swimming for a while before they could slowly adapt. In fact, in this process, the human body consumes a lot of energy.

In addition to the water temperature in the pool affects people's appetite, scientific researchers also found that the temperature of air on land can also affect appetite.

Human appetite is inversely proportional to the environmental temperature. The environmental temperature rises, human appetite decreases, environmental temperature decreases, and human appetite increases. This is why everyone feels no appetite in the summer, but as soon as it is in winter, the appetite is greatly increased.

In addition, the size of the exercise will also affect appetite. Often, the more intensity, the greater the impact on appetite. In other words, the more you practice, the more you don't want to eat.

Researchers found through experiments that they are also riding bicycles. Compared with riding for 20 minutes, the energy consumption of 40 minutes is doubled. However, human appetite does not increase significantly, but it is still possible to decrease.

Therefore, there is also a conclusion: if you want to use exercise to suppress appetite, then it is best to adhere to the medium intensity exercise of more than 40 minutes.

Many people have a misunderstanding during fitness, thinking that the longer the exercise time, the better the effect. In fact, it is really not the case. Real scientific fitness depends on strength, not time. Half -hour high -intensity exercise, the effect is significantly better than one hour of low -intensity exercise.

But anyway, movement, after all, it is better than moving.
