Key result
A 4-week intermittent hypoxic intervention did not significantly improve aerobic or anaerobic performance in elite distance athletes compared to normoxic training (p>0.05).
Why the study?
Intermittent hypoxic training has been noted when standard hypoxic environments are unavailable, but its effect on aerobic and anaerobic performance in elite athletes required investigation.

Absolute Event Rate: 67.02% vs 67.94%
p-value: p=>0.05
A 4-week intermittent hypoxic intervention did not significantly improve aerobic or anaerobic performance, nor hematological parameters, in elite distance athletes compared to normoxic training.
May enhance elite athlete performance; leaves open optimal protocols and safety in larger trials.
Objective: The use of hypoxic training has increased to improve the performance of endurance athletes in recent years. Due to not having the suitable conditions and environment for each athlete and team, intermittent hypoxic training has been noted. The purpose of this study is to investigate the effect of intermittent hypoxic training on aerobic and anaerobic performance of elite athletes. Materials and Methods: A total of 40 elite distance athletes were taken into our study and divided into two groups as hypoxia and normoxia. While using the intermittent intervention for the hypoxic group 5 minutes intervals for a total of 1 hour per day, 3 days per week for a-4 week period, the same normoxic training protocol was used for the normoxic group. Aerobic and anaerobic performance parameters were measured with venous blood samples of the athletes in the first three days before and after hypoxic intervention. Results: When the hypoxia and normoxia groups were evaluated before and after intermittent hypoxia, there was no statistically change in aerobic and anaerobic performance values (p>0.05). Conclusion: We observed that there was not a statistical change of intermittent hypoxic intervention for the performances of hypoxic group. However, the more dose and the duration of hypoxic training, the more amount of performance gain can be achieved.

Eroğlu et al. (2021) conducted an RCT in Healthy elite athletes (n=40). Intermittent hypoxic intervention vs. Normoxic training (ambient air 21% FiO2) was evaluated on Maximal oxygen consumption (VO2 max) post-intervention (p=>0.05). A 4-week intermittent hypoxic intervention did not significantly improve aerobic or anaerobic performance in elite distance athletes compared to normoxic training (p>0.05).
