PhD thesis

Exercise training can prevent and treat numerous chronic diseases including metabolic disorders, e.g., type II diabetes. However, the molecular signals inducing these health benefits are largely unknown.

By illuminating the global phosphorylation status of proteins in human skeletal muscle following endurance, sprint, and resistance exercise, this PhD project found a core set of phosphorylation sites regulated in all exercise modalities. Further, the role of the protein complex pyruvate dehydrogenase (PDC), important for insulin sensitivity, was investigated in humans following exercise.

Using different human exercise models and state-of-the-art methods for measuring signal transduction and insulin sensitivity in vivo, this PhD project provides a greater understanding of proteins regulated with exercise and shows an important function of PDC in insulin-stimulated glucose uptake after exercise.
