Résumé

{This study investigated the effects of acute hypoxic exposure on post-exercise cardiac autonomic modulation following maximal cardiopulmonary exercise testing (CPET). Thirteen healthy men performed CPET and recovery in normoxia (N) and normobaric hypoxia (H) (FiO(2) = 13.4%, ae 3500 m). Post-exercise cardiac autonomic modulation was assessed during recovery (300 s) through the analysis of fast-phase and slow-phase heart rate recovery (HRR) and heart rate variability (HRV) indices. Both short-term, T30 (mean difference (MD) 60.0 s, 95% CI 18.2-101.8
