Study type | Interventional |
The aim is to define in detail metabolic pathways at rest and during aerobic exercise in normal and healthy men and women under normobaric normoxic and moderate hypoxic conditions, using metabolomics technologies based on minimally invasive sampling relying on gas chromatography and mass spectrometry.

Primary | Coefficient of variation of relative quantities of metabolites and physiological parameters related to its dynamic during exercise under normoxic and hypoxic conditions, using GC-MS. | A drop of capillary blood (20 µl) will be collected from the hyperemic earlobe for metabolomic analysis at the times t = 0 min (before starting), 10 min, 20 min and 30 min during the activity, and t = 50 and 60 min taken in the recovery phase. The oxygen saturation and heart rate will be determined at the same time points by pulse oximetry and heart rate monitoring, as well as blood gas analyses and subjective self-perception of energy availability on a quantitative scale throughout exercise. | 6 months |
