Altitude training / intermittent hypoxia (IHT)
Metabolic Health · Oxygen/Pressure
Tier B+
Bottom line
Read Off Label grades Altitude training / intermittent hypoxia (IHT) as B+ (7.2/10) based on strong evidence, med benefit magnitude, and a low-med-risk safety profile.
'Live high, train low' is the gold standard for endurance performance.
Typical use: Live-high train-low (LHTL) 2,200-2,500m for 3-4 weeks; IHT 10-15% FiO2 in 5 min intervals — N/A.
What this is
'Live high, train low' is the gold standard for endurance performance. Intermittent hypoxia devices (LiveO2, CellGym) becoming popular in biohacker circles with less robust evidence.
Mechanism
Hypoxia stabilizes HIF-1α; EPO production; erythropoiesis; increased mitochondrial density and capillarization; possibly enhanced autophagy
Dose & route
Live-high train-low (LHTL) 2,200-2,500m for 3-4 weeks; IHT 10-15% FiO2 in 5 min intervals
