Analysis of who is not suitable for cycling.
Who are not suitable for cycling?
1, who is not suitable for cycling?
1. 1, the first type, men's team. It's not that men are not suitable for cycling, but that they can't do sports with this sport for a long time. Because as we all know, almost all bicycle seats are narrow now. If you ride for a long time, it will have a certain impact on men's testicles and prostate. Under long-term crowding, inflammation such as redness and inflammation may occur. If not adjusted, it may even lead to infertility.
1.2, the second type, patients with cardiovascular and cerebrovascular diseases. This group is common in the elderly. Although it has been reported abroad that cycling is helpful to prevent cardiovascular and cerebrovascular diseases, this premise must be based on correct exercise. Patients with cardiovascular and cerebrovascular diseases must carry out related riding activities under the guidance of doctors and exercise according to scientific methods, otherwise it is likely to lead to accidents, and the most common consequences are high blood pressure and sudden fall.
2, cycling opponents also hurt.
Reason: It is mainly caused by long-term compression of upper limbs during riding, minimal exercise and reduced blood circulation of upper limbs.
Many people will feel numbness and pain in their hands after riding bicycles for a long time, and even writing with pens and eating with chopsticks will be affected. The doctor said this situation? Carpal ulnar tunnel syndrome? .
There is a foot carpal tunnel at the junction of wrist joint and palm, which is composed of pea-sized pisiform bone and fibers. The ulnar nerve passes through the tunnel and distributes to the ulnar side of the hand. When riding a bicycle, if you hold the handlebar tightly with both hands and the ulnar side of your palm touches the handlebar, pisiform bone will get stuck in it. When pedaling uphill or against the wind, accelerating or leaning forward, the wrist joint will inevitably stretch back excessively, which will stretch the ulnar nerve; At the same time, the supporting force of the upper limb increases, and the pressure in the ulnar carpal tunnel also increases, thus causing the above symptoms.
3. What safety precautions should I pay attention to when riding a bicycle?
3. 1, the bicycle size should be appropriate, and don't ride a children's toy car on the street. Don't ride a cart alone.
3.2. Don't learn to ride a bike on the road; Children under twelve should not ride bicycles in the street.
3.3, riding a bicycle should be on the right side of the non-motor vehicle lane, not retrograde; When turning, don't make a sharp turn, slow down in advance, see the surrounding situation clearly, and then turn with a clear gesture.
The way to ride a bike
1, long-term slow riding
The heart rate of long-term slow riding generally does not exceed 65% of the maximum heart rate. More than 20 minutes, will it? Burning? More fat to supply energy, therefore, it is more suitable for obese people with the purpose of reducing fat.
Step 2 ride fast
Fast cycling can make the heart rate reach more than 85% of the maximum heart rate. At this time, the body mainly supplies energy through anaerobic glycolysis of glycogen, which can improve the anaerobic exercise ability of the whole body, especially the thigh muscles, and help to raise the anaerobic threshold. In other words, physical discomfort after strenuous exercise will be postponed, which will help us engage in higher-intensity exercise or stick to high-intensity exercise for a longer time. In addition, fast cycling also has great exercise value for cardiopulmonary function.
3, the combination of fast and slow riding
The combination of fast and slow riding can not only give consideration to aerobic capacity, anaerobic capacity and cardiopulmonary function, but also increase the fun of sports. If we can get scientific guidance and adopt a more reasonable combination of fast and slow exercise, we will achieve better fitness effect.
Step 4 ride at a medium speed
Medium-speed cycling means that the heart rate stays at 65% of the maximum heart rate? 85% is a good way to exercise cardiopulmonary function and aerobic exercise ability.
It is best to use the above methods alternately during exercise, but only one of them is the main one, supplemented by other methods at the same time, in order to achieve better exercise effect.
In addition, bodybuilders should not ride too fast when they start exercising, and the time is generally 20? 40 minutes, if you feel tired, you can ride slowly every once in a while 1? 2 minutes to regain your strength. After a period of time, gradually increase the intensity and duration of exercise.
The benefits of riding a bike
1. Bicycle is one of the best tools to overcome heart function problems. More than half of the people in the world die of heart disease. Cycling can not only compress blood activity through leg movements, but also draw notes from the end of blood vessels. In fact, it also strengthens microvascular tissue, which is called collateral circulation. Strengthening blood vessels can keep you from being threatened by age and stay young forever.
2. Habitual cycling can broaden your mind. Otherwise, the blood vessels will become thinner and thinner, and the heart will deteriorate. In your later years, you will experience the troubles it brings, and then you will find how perfect riding is. Cycling is a sport that needs a lot of oxygen. You should let your heart beat violently, but not for long.
3, cycling can also prevent high blood pressure, prevent obesity, arteriosclerosis, and make bones strong.
Bicycle is a tool to lose weight. According to statistics, a person weighing 75 kilograms can lose half a kilogram by riding 15 kilometers per hour, but he must persevere every day.
5, cycling, not only can lose weight, but also make your body more symmetrical and charming. People who lose weight through exercise, or people who diet while exercising, are in better shape and more attractive than those who only diet first.
