PROFILE
Masashi Miyashita’s research interests are in the physiology and nutrition of physical activity (exercise/sports and daily activities) and public health, with an interest in both the basic science of physical activity and the applied aspects that relate to health in physical activity. Much of his works have examined the effects of physical activity on risk factors for cardiovascular disease. A major focus of his research has concerned the effects of physical activity on fat (triglycerides) metabolism after meals in humans. More recently his activities have expanded to include work on physical activity and appetite regulation, physical activity and atherogenic lipids/inflammatory markers, nutrition and exercise performance, and recovery science in humans. He also has an established network with my domestic and international collaborators for conducting cutting-edge research on physical activity and health.

Our research interests are focused on the prevention of chronic disease and the development of physical performance through physical activity and diet interventions from adolescents to older adults. We are also trying to translate our research findings into practice.

Exercise and postprandial triglyceride: Effects of energy deficit and energy replacement compared

Dietary replacement of an acute exercise-induced energy deficit offsets the postprandial triglyceride (TG)-lowering effect of exercise in young boys and middle-aged men. It is unclear whether these findings are observed when exercise is accumulated in older adults. This study examined the effect of accumulating short bouts of exercise, with and without dietary replacement of an exercise-induced energy deficit, on postprandial TG in older women. This study demonstrated that accumulating short bouts of brisk walking (1.5 min × 20) throughout the day reduced postprandial TG in older women but that dietary replacement of the exercise-induced energy deficit diminished this effect. This underscores the importance of maintaining an energy deficit in relation to exercise to augment the reduction in postprandial TG even when exercise is accumulated in short bouts during the day.
