Sports experts pointed out that due to the special requirements of cycling, the arms and trunk mostly work statically, and the legs mostly work dynamically. When blood is redistributed, there is more blood supply in the lower limbs, and the change of heart rate varies according to pedaling speed and terrain fluctuation. The body is in urgent need of nutrition supplement and waste discharge, so the heartbeat is often 2-3 times higher than usual. Repeated practice like this can make the myocardium developed, the heart enlarged, the myocardial contraction strong and the elasticity of the blood vessel wall enhanced. Therefore, the lung ventilation is large, the vital capacity is increased, and the respiratory function of the lung is improved.
Experts suggest that the amount of exercise for bicycles should be moderate. It's not enough to just focus on the distance you ride. You can keep in good shape when riding a bike meets resistance. Ride for at least 30 minutes at a time, but not more than 60 minutes. Relax your upper body when riding a bike to avoid shoulder and neck pain; Don't press your body too low when riding a bike, or you will limit your abdominal breathing.
