Do Agreements between HRV and Gas Exchange Thresholds Still Hold under Hypoxic Conditions?
Although the V̇O 2 and HR at HRVTs retained alignment with GET/RCP in both normoxia and hypoxia, the degrees of correlation, and equivalence were weaker and the bias and LOA were larger in hypoxia. Therefore, although using HRVT alone for training boundary guidance in hypoxia is a potential option, further investigation including incorporating complementary surrogate markers is recommended.
