Cycling lesson: What is the three non-fit for cycling? [Pic]

Cycling as a speed sport is inherently more dangerous, so everyone must pay attention when they are engaged in this sport. Here the sports experts have given three unsuitable ones. Let's take a look at what the three non-fitness of riding is.

Three types of people are not suitable

First of all, men are not suitable for cycling as a long-term exercise program. Because the bicycle seat is narrow, if the male rides for a long time, the testes, prostate and other organs will suffer from ischemic, edema, and inflammation after being pressed for a long time, thus affecting the production of sperm and the normal secretion of prostatic fluid and semen. Severe persons may even cause infertility.

Second, although many studies at home and abroad have shown that cycling can be beneficial for the prevention of cardiovascular and other diseases, unscientific cycling can increase blood pressure in people already suffering from hypertension without a doctor's guidance. As the burden on the heart increases and the severity of hernia patients increases, concussive sequelae and epilepsy patients are also prone to accidental falls. Therefore, those suffering from these five types of diseases are also not suitable to engage in this exercise regularly.

Finally, adolescents are in a stage of growth and development with soft bones. If you choose to use a low-end bicycle for exercise, you will have to bend the spine for a long time and affect the development of the body. Therefore, young people should pay attention to the correct posture when exercising with a bicycle.

Work on the road is not suitable

Do not choose downtown roads as a workout site during cycling because the exhaust and dust of the car are extremely harmful to people in sports. When cycling, due to increased exercise, heart and lung function increases, if you can not avoid the exhaust gas and dust, then the passive inhalation of harmful gases will be quickly spread throughout the body with the strengthening of heart and lung function, and then poisoned to the body organs. In the short-term, people feel uncomfortable and dry cough; for a long time, people may suffer headaches and weakness. After many years of cycling on the road, passive inhalation of exhaust gas may also cause lung diseases.

In addition, women who are in the physiological cycle are not suitable to engage in this sport on heavily polluted roads because of weak body resistance. In summer, the sun is intense and it is easy to suffer from heat stroke. It is also not suitable for choosing a street as a venue.

Mismatched equipment is not suitable

Because the helmet can effectively reduce the chance of a concussion when falling down, the US insurance regulations require that helmets must be worn for cycling, or accidents do not require compensation. But in our country, cyclists rarely notice this.

In addition, the commonly used protective gear for cycling includes knee pads, shin guards, elbow pads, and wrist guards, which can prevent sprains, bruises, and other injuries during driving. If bicycles are used as sports, these protection devices must be fully equipped.

There is so much stress on riding a bicycle. I haven't noticed it. The three unsuitable riders given by the experts are the result of summing up a great deal of experience, hoping to arouse everyone's attention enough to avoid accidents.
