Why do certain parts of the body feel sore when riding a bicycle?

First: Why is it said that bicycles cannot be ridden for long periods of time?

1. The bicycle seat is narrow and hard. If you ride for a long time, the prostate and other organs will be greatly squeezed, which will cause ischemia, swelling, inflammation and other conditions. In severe cases, it may even lead to infertility. .

2. It is not recommended for developing teenagers to ride bicycles for a long time. Because they are in the peak period of growth and development, their bones and many organs are not yet fully developed. For example, bicycles with lower handlebars will affect the curvature of the spine and easily cause irritation to the waist.

3. People with five types of diseases are not suitable for regular cycling: patients with high blood pressure, concentration and mental stress while riding will cause an increase in blood pressure; patients with coronary heart disease, due to increased exercise, the burden on the heart Aggravation, insufficient blood supply to the myocardium; patients with hernia, it is easy to deepen the severity; patients with post-concussion sequelae and patients with epilepsy are not recommended.

Second: What is the correct riding posture of a bicycle?

1. Cushion angle

Some people often complain of crotch pain after riding a bicycle. This may be caused by excessive pressure on the PP or inner thigh from the front end of the seat cushion. At this time, it is necessary to Check that your saddle is level, and you can even adjust the nose of the saddle down a little, which can reduce wear on your crotch area.

2. Cushion height

The appropriate height of the seat is: when the pedal reaches the lowest point, the legs can be straightened effortlessly and the knees do not need to be bent; when the legs are stretched a little harder When it's straight, your knees can bend slightly and that's fine. Of course, if you are not accustomed to the new bicycle and are not used to adjusting the seat cushion too high, you can lower it a little first and then raise it slowly, putting safety first in everything.

3. The posture of the back and neck

When riding, the back needs to be straight, but not vertical. It should be leaning forward and straight. It should be leaned forward from the hips, not waist or back chest, otherwise it will turn into a hunchback or a shrimp-----not only for good looks, but also to keep the spine as straight as possible, otherwise you will have unbearable back pain after long-term riding; keep your neck naturally straight, not too low Or too straight, otherwise your neck will be sore. If you feel that your neck needs to be lowered and your head drooped to feel comfortable, then you need to rest, and do so as soon as possible.

4. Shoulders and Arms

Shrugging your shoulders is a very wrong habit, which will slow down your control reaction and make you unable to respond as quickly as possible in an emergency. It will also increase the burden on the shoulders, causing shoulder and neck pain. You should relax your shoulders, let them droop naturally, and bend your arms slightly. This will effectively filter the vibrations from the ground and prevent you from suffering from hand pain and shoulder pain.

Third: A brief analysis of the five rules of bicycle seat selection

1. A comfortable seat position should be horizontal or slightly tilted downwards. If the saddle is tilted up, even the best-made saddle can compress the arteries in your buttocks.

2. It is best to choose those wider saddles. The seat area is large and the pelvis can bear the force without affecting other parts.

3. When pedaling, try to ensure that the knees are not fully extended, because that will shift the center of gravity to the person's crotch, causing physical injury.

4. Lift your body frequently when riding a bicycle. This promotes blood flow.

5. The last point is also the easiest to do: stand for 10 minutes every day. This is a must-do task for cycling enthusiasts every day. Staying away from bicycles appropriately, standing and walking for a while every day is very beneficial to your health.

Of course, we cannot give up eating because of choking. Cycling can promote body metabolism, increase blood circulation, and exercise leg muscles, which can bring great benefits to physical and mental health. Therefore, when choosing a bicycle, you must choose a suitable bicycle according to your height, weight, and even body proportions.
