Bicycle is the transportation that we often use in our daily life. But with the development of the times, more and more people do not ride bicycles and drive cars instead. In fact, cycling has many benefits. What are the benefits of cycling for the body? Does cycling have a negative impact on the body?

The benefits and disadvantages of cycling

Bicycling is not only good for exercise, but also helps to protect the environment. Many cycling enthusiasts like to ride their bicycles around and visit various scenic spots. To increase your interest in bicycling, the following are the benefits and disadvantages of bicycling.

The benefits of cycling

1、Bicycling can help you lose weight because it is a simple and easy aerobic exercise that can help your body consume excess fat, which is very beneficial.

2, can improve cardiorespiratory function, enhance breathing volume, improve bad breathing habits, but also exercise the four muscles, enhance the whole body endurance.

3, can improve human sensitivity, prevent brain aging, the reason is that the two legs alternate stirrups help develop the brain, to prevent premature brain aging.

2, excessive cycling has damage to the cervical vertebrae, lumbar vertebrae and knee joints, and the symptoms of this type of injury manifest as pain and suffering, mainly due to incorrect riding posture.

Why cycling saves energy compared to walking

When a person walks, both feet need to support the weight of the whole body, but also to stare backwards, so that the body moves forward, and to overcome the friction between the soles of the feet and the ground, so it is very laborious. When a person rides a bicycle, he or she uses the wheels to roll forward. The friction between the wheels and the ground is the main thing a person needs to overcome, and the effort required to overcome this friction is much smaller than the friction between the soles of the feet and the ground when walking.

And because of the use of the pedals, chains and flywheels on the bicycle and other labor-saving transmission devices, the force is also very convenient. In addition, when walking, the feet have to support the weight of the whole body in addition to overcoming friction. Bicycling, on the other hand, is sitting on the frame, and both feet only serve the task of pedaling, so it is not as strenuous as walking.

In short, walking is more strenuous than riding a bicycle. In your daily life, if you have a bicycle, try not to walk and choose a way to make yourself more energy-efficient, which will help reduce fatigue. In addition, there are baskets on the bicycle, which can also carry a lot of items, making it easy to travel.

How to learn to ride a bicycle the fastest

Learning to ride a bicycle, although many people think it is simple, but for those who can't, it is very difficult, so how can I learn it quickly? Here are some tips to teach you.

Tip 1: Master the balance of the bike

Hold the handlebars with both hands and push the bike along the road. Push the bike slightly to the left at first, and after a while, push it slightly to the right. Then hold the saddle with your right hand and push the bike, with the feeling that the handlebars themselves can rotate in either direction. If the head of the car is folded to the right, push the saddle gently to the right to restore the car to the correct direction, so that you can slowly master the method of controlling the balance of the bike.

Tip 2: Sit on the bike and practice

If you are learning to ride a bicycle, you should sit boldly on the bike, squeeze the handlebars with both hands, and use your feet to push the bike forward and in. It is important to note that you should be calm in the car, not overly nervous, and squeeze the handlebars tightly. Be confident, sit boldly on the seat, do not make the body tilted to the side. If the car is tilted to one side, just turn the handlebars towards the tilted side, and the car will be set right.

Tip 3: Learn pedal movement

Squeeze the handlebars with both hands, put your right foot across the frame against the right pedal, and paddle the ground with your left foot. Once the bike is pushed, take your left foot off the ground, hold it against the left pedal, and move your butt to the saddle at the same time, and both feet will begin to turn the pedals evenly.

How to take care of your bike after riding

You must take good care of your bike after riding it, otherwise it will be easily damaged. What should you do after riding a bicycle? The following points are quickmarks.

Clean up well on sunny days

After riding a bike, remove the mud and oil from the car. If the car is often riding on dusty roads, the cleanup needs to be done once a week. Each time you remove the dirt and oil, you must also re-check the car once again.

If there is mud on the car, you should brush it with a soft brush and then wipe the frame and handlebars with a soft cloth. As for the tires and fenders, they should be wiped with a wet cloth first, and then dried with a dry cloth.

Take good care of your bike on humid days

After riding a bicycle on a rainy or humid day, you should clean it up immediately. First, use a smooth piece of wood to carefully remove the mud on it, then brush it clean and dry it with a dry cloth. As for the metal-plated part, it should be wiped gently with a cloth soaked with oil.

For spokes, front and rear axles, chains and other unpainted metal parts, use a brush dipped in kerosene and dry with a cloth.

Why do bicycle tires break easily in summer?

At a certain temperature, there is a certain amount of air that can be pumped into a bicycle tire. If too much air is pumped into the tire, the volume increases and the air expands outward, which will increase the original pressure on the tire. If the pressure of the air expansion is too large, the strength of the tire can not withstand the force of this expansion, it will rupture.

In addition, the force of the air in the tire to expand outward in addition to the number of gas played into the relationship, but also with the outside temperature. Because the volume of the gas increases with the temperature, when the outside temperature increases, the volume of the air inside the tire will also increase, which will also increase the force of the outward expansion of the air. Therefore, when a certain amount of air is injected into the tire, if the outside temperature rises, the air will expand and cause the tire to rupture.

In the blind listen to the indoor and outdoor temperature, or morning and evening and noon temperature difference, often due to the low temperature of the place to the car tire into a sufficient amount of air. When the car goes to the high temperature place, the air overheating occurs significant expansion, resulting in tire rupture. Therefore, in the hot summer should not be too much air into the car tires, in addition, should try to avoid the car in the sun.
