For example, the left bifurcation bends to the right, and the right bifurcation bends to the left until the pain is relieved.

At the same time, massage your hand simply and slowly with the breathing frequency until the pain is weakened.

At the same time, the expanded cavity also leaves enough space for the expansion of the lung; On the contrary, when exhaling, the diaphragm and intercostal muscles relax and retract upward, the upper and lower diameter of the thoracic cavity decreases, the air pressure in the thoracic cavity increases, which helps to discharge the metabolic waste gas in the lung, and the volume of the lung decreases at the same time.

  One of the main causes of “bifurcation” is caused by spasm of respiratory muscle (diaphragm), which often occurs in the lower right rib.

65 middle school, checks scientifically.

The ligament on which the diaphragm depends will spasm, and finally lead to bifurcation.

Therefore, in the process of running and other sports, I hope everyone can warm up, protect, exercise scientifically and exercise moderately.

Don’t let the sports that should strengthen the body hurt the body in turn.

How did the “fork gas” problem that plagues many runners happen? How should runners adjust scientifically to reduce the occurrence of bifurcations during exercise, and how should they alleviate the discomfort caused by bifurcations? To understand the causes of “bifurcation”, we must first understand how the human body breathes.

When running, the breathing accelerates, and the diaphragm will begin to become more and more tired and can not move up and down normally.

However, if the above methods can’t relieve the pain of your bifurcation, you should stop running immediately, straighten your arms, lift your head over your head, and bend your body to the opposite side of the bifurcation position.

In addition, after stopping running, you can put your hand on the pain part of the bifurcation and try to take a deep breath within the acceptable range.

It can be seen that diaphragm plays a very important role in respiration.

As we have just introduced, the diaphragm is the main respiratory muscle in the middle of the chest and abdomen.

If you don’t want to stop running immediately, you can first observe your current running rhythm, pay attention to which foot corresponds to the landing when you exhale and inhale, and then deliberately disrupt the rhythm and replace it with another foot.

As the temperature gradually decreases and the temperature difference inside and outside the human body increases, bifurcations are more and more likely to occur.

After understanding the causes of bifurcation, we can take this as the basis to reasonably and scientifically prevent the occurrence of bifurcation.

The respiratory movement of human body is completed by the cooperation of lung and human diaphragm and intercostal muscle.

If you must breathe with your mouth, don’t open your mouth and breathe fiercely, but half open your mouth to let air enter your mouth from between your teeth, so as to prevent direct contact with cold air, resulting in too strong stimulation and bifurcation.

For example, get well prepared and warm up before running; Pay attention to the correct breathing method during running, and try to breathe through the nose in cold weather.

When inhaling, the diaphragm and intercostal muscles contract and pull down to increase the volume of the thoracic cavity and reduce the air pressure inside the thoracic cavity, which is convenient for external air to enter the lung.

The most important is that the diaphragm is located at the top of the abdominal cavity and the bottom of the thoracic cavity, that is, near the boundary between the thoracic cavity and the abdominal cavity.

Winter is coming.

Don’t worry if something goes wrong during your run.

In recent years, with the continuous improvement of national health awareness, more and more people love running, but many “novices” or “beginners” will always encounter a headache problem – “bifurcation”.

It is mainly composed of muscle tissue.

At this time, runners will feel great pain in their right rib.

Specifically, if you inhale when you step out of your left foot, change to inhale when you step out of your right foot.
