Matthieu Clauss

Matthieu Clauss is a PhD candidate and Lecturer in Metabolism at the Institute of Physical Performance, Norwegian School of Sport Sciences. His academic work bridges exercise physiology and biochemistry, with specialized expertise in protein metabolism during endurance activities. His research has been published in leading sports science journals including Medicine & Science in Sports & Exercise and Scandinavian Journal of Medicine & Science in Sports.

His educational foundation includes:

• Master's degree in sports biology from Université Paris-Saclay
• Master's degree in biochemistry from Chimie ParisTech

Clauss's research program systematically investigates protein degradation in skeletal muscle during endurance exercise, with particular focus on urinary nitrogen excretion as a key biomarker. His work integrates exercise physiology, cell biology, biochemistry, and nutrition to understand how different exercise parameters (intensity, duration, volume) affect protein metabolism. He examines metabolic responses through comprehensive measurements of plasma metabolites, hormones, and nitrogen balance during and after exercise.

Analysis of his publication trajectory reveals consistent focus on metabolic responses to endurance exercise, particularly cycling. His research examines how nutritional interventions impact metabolic markers and performance outcomes, with recent work including systematic reviews on protein oxidation and experimental studies measuring nitrogen excretion during mixed exercise protocols. This body of work demonstrates methodological rigor and practical relevance for sports nutrition guidelines.

As both a PhD candidate and Lecturer in Metabolism, Clauss actively contributes to research while teaching academic courses. His collaborative approach is evident in numerous co-authored publications with researchers across multiple institutions, reflecting an integrated approach to exercise science research.
