The aim of this study is to investigate and compare the effects of two different pre-acclimatization protocols on physiological exercise parameters in hypoxia. For this purpose, participants perform maximal bicycle spiroergometry in normoxia and in hypoxia (simulated altitude 4,000 m). Subsequently, depending on their group assignment, they undergo one of two pre-acclimatization protocols or no pre-acclimatization (control group). The pre-acclimatization protocols include a) six 3-hour passive exposures at 4,000 m or b) two nights at 3,000 or 3,500 m. Afterwards, the tests in hypoxia and normoxia are repeated.
The results will provide insights into whether these pre-acclimatization protocols have a positive effect on exercise responses and performance at altitude. In the long term, this study aims to contribute to the development of evidence-based strategies for altitude preparation, e.g., for mountaineers and trekkers.
