Conditions

Altitude Hypoxia

Brief summary

The investigators expect to find that different intensity and altitude exposure levels will show what kind of intermittent exposure protocol is more beneficial to athletes and healthy individuals that experience acute exposure to altitude during exercise. This may furthermore be related to acute altitude exposure for recreational exercise use as well.

Interventions

OTHERSimulated altitude

Participants will exercise in simulated altitude will range between 2100 feet and 16400 feet and will increase according to arm guidelines

OTHERPlacebo simulated altitude

Participants will exercise at sea level at similar percentage of intensities to the simulated altitude group.
