Biomedical Signal Acquisition of Hepatobiliary and Portal Vein Before and After Exercise

Abstract

In clinical medicine, the research on the hepatobiliary system was proved successfully. In the field of sports medicine, there was little knowledge about the morphological changes, blood distribution, physiological and biochemical as well as pathological changes in the liver, gallbladder and portal vein during exercise. Therefore, studying the function of hepatobiliary system in sports was a problem worthy of attention in sports medicine, and it was also a scientific field that should be urgently studied. Taking exercise-induced abdominal pain as an example, in exercise-induced abdominal pain, the right upper abdominal pain was mainly caused by changes in liver, gallbladder and portal vein. Based on sports medicine, there was little research on the liver, gallbladder and portal vein systems, and the incidence of right upper abdominal pain during exercise was high. The actual mechanism and etiology of the disease still needed to be further confirmed. For this reason, this sports discomfort became the focus of this study. In addition, a safe and effective color Doppler instrument was used to measure the liver and gallbladder and portal vein. The liver, gallbladder and portal vein data before and after exercise were recorded. Based on preliminary experiments and practical results of small samples, it was demonstrated that the liver was ischemic during exercise. It is concluded that this study can lay a foundation for the future research on the liver and biliary portal system, and it is expected to provide safe, non-invasive, reliable, and new indicators for the medical supervision of sports medicine.
