Why the study?
Does the elevation training mask affect heart rate variability during cycling in healthy adults?
Does the elevation training mask affect heart rate variability during cycling in healthy adults?
The elevation training mask induces modest hypoxaemia and delays autonomic recovery but does not alter HRV during cycling in healthy adults.

May delay post-exercise autonomic recovery with ETM; leaves open equivalence to altitude training benefits.
) induces modest hypoxaemia. Although this device did not affect HRV changes during cycling, it seems to delay the cardiac-autonomic recovery from exercise. Healthy adults may be required to perform high-intensity exercise with an ETM to simulate a hypoxic environment, but future studies are needed to determine whether repeated exposure to this condition provides similar benefits as altitude training.
