What should you pay attention to when cycling for fitness?

　　In our country, bicycles have always served as a means of transportation for most people, and many people regard cycling as a way of fitness. But cycling will affect male The statement of erectile function makes some people have lingering fears when cycling for fitness. Is this statement true or false? Huang Guangmin, chief physician of the Institute of Sports Medicine of the State Sports General Administration, believes that cycling will not affect male erectile function, but will actually help.
　　
　　When riding a bicycle, the legs are constantly moving. Because the muscles that control leg movements nerve The nerves that cause penile erection belong to the lumbar plexus. Cycling exercise It strengthens the legs and indirectly exercises sexual function. If you lean forward and pedal while riding a bicycle, especially a racing bicycle, the bicycle seat will stimulate the perineum and act as a local massage.
　　
　　If you can insist on cycling properly every day, with correct riding posture and a moderately high seat cushion, it will not only be good for the perineum, but also help the erectile function of the penis. A survey found that male cyclists have the best erectile function. Huang Guangmin said that the reasons for erectile dysfunction are relatively complex. In addition to emotional and psychological factors, there may also be pathological reasons.
　　
　　Some people say that pedaling on the soles of the feet will massage the Yongquan point, which can improve the regulation of the urogenital system. But Huang Guangmin explained that the Yongquan point is on the sole of the forefoot, not the sole of the foot, and pedaling on the sole of the foot will not play the role of massaging the Yongquan point.
　　
　　Huang Guangmin emphasized that many people believe that just riding a bicycle can achieve the purpose of exercise. But in fact, the exercise effects of different cycling methods vary greatly. There are two main ways to ride a bike. The main purpose of leisure cycling is to relax muscles and deepen breathing, thereby relieving physical and mental fatigue. There is also a training-style cycling method, which stipulates the riding speed each time and controls the riding speed based on one's own pulse strength. This can effectively improve cardiopulmonary function and exercise the person's cardiovascular system.
　　
　　Huang Guangmin introduced that cycling can be used for strength, speed, endurance and other aspects of training; speed training is carried out by riding fast on flat roads; endurance training is carried out by riding at a lower speed for a long time; mixed training is a combination of the above three methods.
　　
　　From the perspective of aerobic exercise, there are two ways to achieve an ideal exercise effect when riding a bicycle. One is to mobilize yourself to a certain intensity and let your body heart rate Between 120-180, maintain endurance training at this heart rate for more than 30 minutes. The other is fast riding for a short period of time, but this method requires aerobic exercise (slow riding).
