I don’t know if anyone is like the author and I. Often, halfway through exercising and running, you will suddenly feel pain in your abdomen, or even a tingling feeling, but stop exercising. In fact, this may be commonly known as exercise stitch (stitch), the official name is called Exercise-related transient abdominal pain (ETAP). Below I will mainly based on Darren Morton and Robin Callister's article published in "Sports Medicine" in 2014, to give you a brief introduction to what is ETAP.
What is an "Exercise Bias" (ETAP)? ETAP often occurs during repetitive trunk stretches such as running, horseback riding, swimming, and more. Patients experience company banner design abdominal tingling, cramping, soreness, or a feeling of being pulled. According to research statistics, during a running event, about one in five athletes will experience symptoms of ETAP. The location of pain usually occurs in the area from the upper abdomen to the center of the abdomen, especially at the base of the ribs or the outer side, and the pain is much more likely to appear on the right side than on the left side. However, there is a chance of pain throughout the abdomen, and may even be combined with shoulder pain (Shoulder tip pain). Possible factors affecting the occurrence of ETAP: Age: There are many studies showing that young people are more likely to develop ETAP.
Physical conditioning: High-intensity physical conditioning may reduce the symptoms of ETAP, but it does not completely eliminate it, and in fact many athletes still complain that they have ETAP. Body Size and Body Posture: Recent studies have shown that body size does not seem to have much to do with the experience of ETAP, meaning that obese people, or people of a certain body type, do not particularly induce ETAP. However, in terms of body posture, people with a hunched back seem to be more likely to get ETAP, and the more severe the hunched back, the stronger the ETAP pain. Type of exercise: As mentioned earlier, activities such as running, horse riding, and swimming that require the trunk to repeatedly exercise in a stretched state are more likely to cause ETAP, but the intensity of the exercise itself does not seem to have much to do with ETAP. Pre-exercise diet: A high percentage of people with a pre-exercise diet have been seen to have symptoms of ETAP across studies at different times, and two of these studies have shown that drinking hypertonic fluids is more likely to trigger ETAP (so-called hypertonic fluids).
