Many people have experienced this experience when they are running: in the process of exercise, a certain part of the body will suddenly send severe pain. The pain usually occurs in the lower part of the chest on the left or right lower abdomen. Most runners have suffered from this condition, and they have to slow down and start walking until their bodies return to normal
Nowadays, researchers have given this kind of pain a very academic name, which is called "transient lower abdominal pain caused by exercise" (ETAP). In the folk, we often call it "Chaqi". Well, we can ignore its scientific name. What people know is that this symptom can greatly affect the performance of athletes, especially swimmers and runners, and affect their competitive performance.
What is the cause of the bifurcation?
At present, there is no definite conclusion on the cause of Chaqi in medical field, but some convincing theories have emerged. Most of these scientists hold the view that the generation of forks is related to our diet before exercise
Some studies have shown that people have the most side effects when swimming and running. Bifurcations usually occur in one side of the lower abdomen and result in poor performance. Even if you are not an athlete, the results also show that the occurrence of bifurcations is not related to the athlete's gender and body mass index (BMI). But young people seem to be more susceptible to side effects.
It is known that the most closely related factors are the type of diet and eating time before exercise. Drinking high sugar and high osmolarity drinks before and during exercise can lead to side effects, especially for people who are often bothered by them, according to a study. And how much food you eat before exercise seems to have nothing to do with the occurrence of side effects
Another complicated explanation is that repeated stretching of the ligament between the diaphragm and the viscera (especially the liver) during exercise is the cause of the bifurcation problem. Different ways of breathing lead to this problem. When running, people usually change their breath every two or four steps. Generally speaking, most people exhale when the left foot steps out, but a few people exhale when the right foot steps out. Since the liver is located on the lower right side of the chest, if you exhale while stepping out of the right foot, the diaphragm will move up and the liver will fall due to the right foot stepping out. Repeated stretching of ligaments can cause diaphragm spasm and cause bifurcation
What if something goes wrong?
If you have a fork in your running, stop running immediately and put your hand on your right abdomen and rub it with the frequency of your breath. During running or swimming, please take deep breath as much as possible. The theory of "ligament stretching" tends to think that shortness of breath will increase the probability of bifurcations. This is because the diaphragm only slightly rises and falls during each breath, and ligaments are always in a tense state and can not be relaxed. Therefore, bifurcation is more likely to occur.
In addition to these, we have some suggestions that can help you stay away from the trouble of forks:
Plan your time to eat before exercising to make sure that most of the food is digested during exercise - that is, don't exercise immediately after meals. Avoid drinking drinks with high sugar content or high osmotic pressure before or during exercise. Fully stretching before exercise helps to reduce the chance of side effects. You can do this: lift your right hand up and stretch as far to the left as you can, hold it for 30 seconds, relax, and then lift your left hand up and stretch to the right. Please slow down the movement until it subsides. You can try to massage the side of the bifurcation and lean forward as far as possible so that the diaphragm can be stretched as much as possible, which can help relieve the pain.
