Numbness that can't be ignored For cyclists, riding has become an indispensable part of their lives. Bicycles help you lose weight and burn excess fat on your hips and thighs. But many men complain that the penis and scrotum will feel numb after riding a bicycle for several kilometers. Researchers in Boston and Italy found that the longer men ride bicycles, the greater the risk of impotence or loss of sexual desire. Austrian research institutions have also conducted surveys: many men who like to ride mountain bikes have calcification in their scrotum after wound healing. Researchers say that about 5% of people with high riding intensity will have moderate or severe impotence. Seats are the killer of men's sexual ability. Cyclists, especially men, must be very careful when choosing bicycle seats. Through a number of data analysis, it shows that the car seat not only brings numbness to men, but more importantly, it has become a real dangerous killer of men's sexual ability! The traditional bicycle saddle, especially the saddle with narrow back and sharp front, will make men fall into the embarrassment of impotence. The study also found that some seemingly beautiful and avant-garde bicycle saddle designs are also very harmful to the male reproductive system. If the seat is too high and the cyclist is short, it will not only cause discomfort and uncoordinated movements when riding, but also cause constant friction between the perineum and the seat because the cyclist can barely move up and down. Especially, the front of the car seat is high, which makes the center of gravity of the occupant move backward, or the bumpy road surface makes the car limp seriously when driving, which is more likely to stimulate the perineum and cause congestion, swelling and injury of the prostate. Many men who ride bicycles are generally reluctant to talk about their reproductive system diseases, especially sensitive topics such as impotence. There are still many cyclists who don't know that their impotence is related to cycling. An American scientist who specializes in the effects of cycling on human health said bluntly that the question now is not whether cycling will damage men's erectile function, but how people should solve this problem. Five rules of car seat selection Now, some manufacturers have begun to develop car seats that meet ergonomic requirements. In the United States, a convenient seat ("eastseat") was favored by male customers as soon as it went on the market because it had no seat head or the seat head of "sq-seat60 1" was engraved with obvious marks. If you can't buy the above seats, you should follow the following five rules about installing seats and riding bicycles: 1. A comfortable seat position should be horizontal or slightly inclined downward. If the car seat leans upward, even the best car seat will compress the hip artery. 2. It is best to choose those wider car seats. The pelvis with large seating area and large bearing capacity will not affect other parts. 3. When pedaling? Try to ensure that your knees are not completely straight, because that will shift your focus to your crotch and cause physical injury. You should always lift yourself up when riding a bike. This can promote blood flow. 5. Finally, it is the easiest thing to do: stand 10 minutes every day. This is the daily work of mountain bike enthusiasts. This is also very important for cyclists on flat ground. Stay away from bicycles properly and stand for a while every day. Walking for a while is good for your health. We can't give up eating because of choking. The great benefits of cycling to physical and mental health far outweigh the negative effects mentioned above. As declared by the International Heart Congress held in Anaheim, USA in 200 1, 165438 10, heart patients can improve their heart quality by riding bicycles. Italian medical researchers pointed out that the patient's heart power and blood supply to genitals have also been improved by engaging in sports. Therefore, when choosing a bicycle, you must choose a suitable bicycle according to your height, weight and even body proportion, and you can also adjust your bicycle according to your own situation. In a word, you should make your bike serve you and become an active member in your healthy and fashionable life. Tips: Five secrets of cycling fitness no 1.
