A total of 2033 articles were obtained from four databases. However, only 11 articles were deemed to meet eligibility criteria after thoroughly examining titles, abstracts, and full-text content.

The studied population encompassed different healthy cohorts, which comprised sedentary males (n=6), trained males (n=2), mountain climbers (n=1), and older adults (n=2). Included studies preferred using bicycle ergometers (72.7%, n=8) as the exercise modality and 10 studies (90.9%) utilized hypoxia chambers to mimic a normobaric hypoxia environment. Four studies (36.4%) opted to utilize hypoxia chambers to mimic an altitude of 2733 and 4460 m.
