Research directions
Neuromuscular Physiology
The mechanisms underlying fatigue from physical effort are not well understood. The phenomena at muscle level such as accumulation of metabolites and the integration of afferent information at the level of the central nervous system play roles that are subject of ongoing research.
Ethics of doping and anti-doping
Doping and anti-doping in elite sport raise important ethical questions. A multi-disciplinary approach permits a better description of the limits, the potential and the obstacles of anti-doping.
The cardio-pulmonary phase at the onset of exercice
Oxygen consumption at the onset of exercice does not represent increased use of oxygen by metabolism, but an increase in oxygen uptake due to increased venous return from variations in intra-thoracic and abdominal pressures. Using a double plethysmographi we study the mechanisms.
Acute mountain sickness
Acute mountain sickness is still badly understood. We study possible mechanisms. One axe concerns the role of cortisol and its regulation.
Energy balance in humans
Regulation of energy balance in humans is still badly described. We study with the use of large cohorts the relationship between micro-nutriment deficiencies and energy expenditure from physical activity.
Built environment and physical activity
The built environment influences physical activity behavior. Using a multi-disciplinary approach we study the effects of a relocation to a more physical activity friendly environment.
