In the process of riding for a long time, incorrect posture, movements and parts will cause discomfort in different parts of the body. When you feel pain, you should be vigilant, find out the reason and correct it in time. 1. The tendon of the foot is located at the back of the ankle, connecting the peroneal muscle with the heel. The pain here shows that there is something wrong with your pedaling skills. When the seat is too high, you must try your best to pedal with your toes. Excessive exertion for a long time will cause tendon injury. When traveling for a long time, you should try to pedal with different parts of your foot to avoid excessive tension of your tendons. 2. The situation above the ankle can also cause ankle pain. If you have flat feet, it will help to put a plastic pad in your shoes. If the crank and pedal are bent, the feet will swing back and forth and left and right when riding, which will also cause ankle discomfort. Back pain is usually caused by incorrect riding posture. When riding a bicycle, the back should be arched, and the hip joint and shoulder should not collapse. Such a bump will make the back arch slightly again, which is harmless. If the back collapses, bumps will further sink the back, causing severe pain in the spine. Many people who feel back discomfort will modify the front handle very high, so that they can sit up straight and keep their spine straight, which is wrong. Riding on the rough road, the straight spine has no buffer, and the bumps will make the spinal joints squeeze together, which will aggravate the back pain. Foot discomfort is usually caused by shoes and socks. Too soft soles will concentrate the pressure on the feet, and too high gear ratio will force you to pedal with great force, which will cause foot pain. Good shoes and socks can prevent foot wear. 5. Long-term riding with your fingers will numb your fingers, so you should exercise properly. Wearing gloves can prevent the palm from being scratched. Incorrect upper body posture will cause discomfort to hands, shoulders and elbows. There is a very important nerve between the two thick meat pads in the palm of your hand to avoid oppression here. Do not use thick foam gloves. When holding the handlebar, the foam will fill the gap between the meat pads and squeeze the nerves. The same applies to car seats. When riding a bike, your hands and arms should be in a straight line and your wrists should be relaxed. 6. Knee pain is a common phenomenon, which is mainly caused by the following aspects: (1) riding too hard or using too high transmission ratio under the condition of insufficient strength; (2) The seat is too low, resulting in excessive bending of the knee joint; (3) When pedaling, swinging the legs left and right will wear the knee joint. Pay attention to whether the knee joint shakes when riding, and correct it subconsciously to make the movement smooth. Strengthening the strength of thigh muscles can make the pedaling action more stable. 7. The shoulder seat leans forward too much, and the weight of the body is pressed on the upper limb, which will damage the shoulder for a long time. Too narrow handlebars will squeeze shoulders and chest, causing discomfort.
