Last time we talked about the debugging of the dynamic bicycle, this time, it is time to talk about how to ride the problem. I believe that most of the friends who have been to the gym and contact with the dynamic cycling is not new to this, but often because of some carelessness, resulting in some unnecessary injuries. So, how to ride a dynamic bike should be to reduce the risk of injury? Let’s discuss the following (the following are personal experience, such as discrepancies can be ignored): Peking University Third Hospital Rehabilitation Medicine Center Li Hang Relaxation bit After the end of the bike debugging, we will be fixed in the shoe cover feet, the next ready to start the class. Of course, the beginning part of the course is the warm-up. When warming up, we use the relaxation position, get up and sit straight, stretch our hands from the hips to the handlebar position, while the body leans forward with the natural relaxation of both arms, at this time the elbow joint will be slightly flexed, while the shoulders should also be relaxed, try not to shrug the shoulders. Sitting relaxed, both arms naturally down hands collected in the hips arms forward to the handle finally completed as shown in the picture, the body leaned forward, shoulders, both arms relaxed, palm root top handle, fingers relaxed Racing bit After a simple warm-up, we have to enter another part, that is, the most exciting part of the bike exercise: sitting racing (a great help to improve cardiorespiratory function). This section requires good control to achieve high speed body stability, but in the classroom will often find a part of the students either very hard to accelerate, or body shaking violent, the latter on the spine and lower limb joints damage is great, in the long run will reduce the life of the sport. Therefore, a more economical and healthy posture should be chosen to complete this section. Racing start position, the body slightly forward, elbow joint slightly flexed, eye front below the elbow joint do not overextend, so that not only not speed and will increase the swaying amplitude of this position to simulate the breaking wind riding position, then hands to the middle of the position, that is, the racing handle, as shown, the center of gravity again lowered, can be slightly increased resistance to simulate the breaking wind sprint, this section to be more intense than the sitting position racing, increase cardiorespiratory fitness better. This time we first understand the two relatively simple movements, choose a good riding posture on your spine, all joints and surrounding muscle groups are a good training. Let’s look forward to the next installment! This article is published with the authorization of Dr. Hang Li.
