Exercise and postprandial metabolism of fuels
The postprandial state poses a challenge to metabolic homeostasis. Co-ordinated regulation of metabolism across tissues achieves a restoration of homeostasis after the ingestion of macronutrients increases circulating concentrations of glucose and triacylglycerol. Exercise can have acute and chronic effects on metabolism which contribute to the regulation of postprandial metabolism. Specifically, exercise immediately increases glucose uptake into skeletal muscle, and also has longer lasting effects for the hours and days after exercise. Regular exercise training can cause adaptations in muscle which contribute to good glucose control. A single bout of exercise can also reduce postprandial triacylglycerol concentrations on the day after exercise.
A summary of the evidence and highlights from key studies will be presented for each of these topics. Overall, this webinar will highlight many of the latest studies in the area and provide new perspectives to viewers with some existing knowledge, but it is also suitable for those who are new to the area of exercise and postprandial metabolism.
What will I gain from this webinar?
- You will be able to describe the physiological regulation of postprandial blood glucose and triacylglycerol concentrations
- Be able to critically discuss the evidence on the role of exercise in lowering blood glucose and triacylglycerol concentrations
- You will have an understanding of the mechanisms by which short and longer-term exercise can alter blood glucose and triacylglycerol concentrations.

Instructor
Javier Gonzalez is Professor of Nutrition and Metabolism at the Univesity of Bath. He is interested in human fuel use. How we get fuel from our diet, burn fuels during exercise; and store fuels when they exceed our requirements. His research group employs a variety of methods to understand human fuel use, including indirect calorimetry, tissue biopsies and stable isotope (IV) infusion and ingestion. Javier joined the Department for Health at the University of Bath in 2014 as a Lecturer (Assistant Professor) before being promoted to Senior Lecturer (Associate Professor) in 2017, Reader (Associate Professor) in 2020 and Professor of Nutrition and Metabolism in 2022. He is also a consultant to sports teams and industry. In recognition of his research, he received the Julie Wallace Award 2018 from the Nutrition Society. He is also an an Associate Editor for the International Journal of Sport Nutrition & Exercise Metabolism.
