The drag racing is essentially an aerobic sport, and this means that muscles work best if there is an adequate amount of oxygen, leading them through the inspired air from your lungs and carried by the blood.
How much the more intense the effort the greater the quantity of oxygen ’ that muscles use, and you also get to situations in which the physical effort is so high that oxygen is no longer sufficient, and muscles, to continue to support the effort, produce high quantities of lactic acid. In this case, when lactic acid accumulates, it is called aerobic effort.
Hence the breathing is an important aspect for each sport. Every athlete can act respiratory gymnastics through specific exercises that improve the tone and the efficiency of respiratory muscles (external and internal intercostals, elevators of the ribs, SADA and diaphragm), such as large circular movements of the arms, shoulders, also associated with inspiratory and expiratory acts. Also the same respiratory stimulation which occurs during the run, especially when you run at high speeds, suffice to improve the efficiency of the muscles of respiration.
Breathe in the right way, alternating inspirations and expirations According to the motion, it is of paramount importance in training, whether it's fatigue, whether it's sports disciplines. It is necessary to know how to toggle between the two phases of breathing, depending on the effort expended, but in any case it is important to do not interrupt never breathing itself, even if the effort supported would instinctively do it.
During training, so if you are unable to switch between inhalation and exhalation according to the pace recommended by your discipline, you should breathe naturallyAccording to a "normal" pace.
You can safely breathe through the nose if physical exertion to be supported is rather bland, but with increasing intensity the muscles need more oxygen and becomes natural open mouth looking for a lot of air. If you wanted to insist not to open his mouth even when the race pace is sustained, we find ourselves soon in oxygen debt with lungs that burn and heavy legs for lactic acid build up.
