The application of intermittent exposure to hypoxia – hyperoxia, IHHT, as form of training to improve exercise performance has not been investigated yet. This case study reports on the effects of a 3-week daily intermittent hypoxia (11%О2) – hyperoxia (30%О2) training on intermittent exercise (one minute at 85% of maximum workload, Wmax, followed by one minute at 50% Wmax, this stage being repeated until exhaustion). Our subject was an 21 years old amateur football player who showed an impressive improvement of his intermittent performance after IHHT. 30 stages (vs 14 at baseline) were completed, Heart Rate was lower by 13 beats/minute (182 at baseline vs 169 after IHHT) and blood lactate was also reduced at the end of the intermittent exercise test (5.8 after IHHT vs 7.3 mmol/l). Thus, IHHT seems very promising to improve cardiopulmonary efficiency and lactate removal when exercising intermittently.
