Dr. Sumida’s initial research focused on the impact of endurance training on hepatic gluconeogenesis using the liver perfusion method and isolated hepatocytes. These investigations revealed that endurance training elevates the glucose production capacity of the liver that could help to prevent the decline in blood glucose concentration during prolonged exercise. Dr. Sumida used these same techniques and switched his research to investigate the sex differences for hepatic gluconeogenesis following chronic alcohol consumption. This research demonstrated that female animals were more susceptible to alcohol-induced hypoglycemia compared to males. Recently, his research has taken a different path. He currently investigates the impact of resistance training on bone formation during the growth period. These studies are revealing the existence of an exercise threshold for bone formation as well as sex differences in the training-induced response.
