this newspaper (reporter wei wei, correspondent yuan xiaoxia) eating while running, even hot dry noodles and hot pot noodles, in recent years, the food in the supply stations of many marathon races is rich and colorful. many runners can't help but ask, will eating like this cause gastrointestinal discomfort when running a marathon? the 2024 taiyuan marathon is about to start. on september 20, li ming, a doctor from the surgery center of the affiliated hospital of shanxi university of traditional chinese medicine, answered questions for everyone.
in a marathon, it is crucial to set up supply stations along the way. professional runners will replenish energy in time according to their own conditions in order to restore their physical strength. in traditional marathon events, the food provided by the supply stations is characterized by efficient energy replenishment, mostly bananas, energy drinks, energy gels, chocolate and other portable and easy-to-eat foods. experts say that high-energy density (mainly carbon water), clean, and easy-to-digest energy supplies should be selected during the competition to avoid metabolic and digestive burdens. for running a full marathon, it is recommended to replenish the first energy gel half an hour after the start of the run, and then an energy gel every half an hour. water replenishment should also not be neglected. drink about 500 ml of water per hour, and replenish electrolytes such as sodium and potassium. it is recommended to supplement isotonic drinks for better absorption.
some people worry that eating while running will induce appendicitis. dr. li ming said that the main cause of appendicitis clinically is the obstruction of the appendix lumen and bacterial invasion. studies have shown that it usually takes 4 to 6 hours for food to enter the duodenum from the stomach, so the food is still in the stomach right after a meal and has not reached the appendix at all, so appendicitis is unlikely to occur. some people experience abdominal pain when exercising after a meal, mainly because a large amount of blood is required for digestion and gastrointestinal movement after a meal. at this time, when exercising, the muscles of the whole body also need blood supply and oxygen supply, and the stomach muscles are ischemic, causing gastrointestinal spasms and pain.
