BACKGROUND: Over the past 2 decades, our studies have revealed that despite extensive research, many unanswered questions persist regarding hypoxic preparation and the resulting adaptive response. For these reasons, we believe it is essential to investigate the impact of environmental hypoxia at altitudes below 1500 m above sea level on the parameters monitored in the athlete’s biological passport (ABP). METHODS: The research was conducted as a pilot part of research on a group of seven Slovak endurance athletes (4 males, 3 females) aged 22-27 years who are active in athletics and cross-country skiing. All participants have extensive experience with hypoxic training (more than 5 years). As part of the research, we monitored their adaptive response to hypoxic conditions at altitudes up to 1350 m above sea level. RESULTS: The findings from the study conducted on seven athletes affirm that, contrary to typical interpretations (such as those in the ABP sampling protocol), even hypoxic conditions at 1350 m above sea level can have a notable impact on the outcomes analyzed in the ABP. The results showed that exposure to hypoxia below 1350 m above sea level resulted in a reduction in hemoglobin levels, while a contrary trend was observed for reticulocytes. This trend was reflected in the Off-score, showing a decrease across all cases. CONCLUSIONS: The data obtained confirmed the effect of hypoxic conditions at altitudes up to 1350 m above sea level on erythropoiesis.
