Athletic Performance & Apnea
Intermittent Hypoxic Training (IHT)
- Structure
- Breathing ambient air, alternating with breathing air from a machine that has reduced oxygen (e.g., 10-15% O2) via a mask.
- Benefit & Nervous System Impact
- Triggers EPO production, increases red blood cells; Adaptive.
- Duration & Rationale
- 30-60 min (Clinical/athletic protocols vary).
- Best For
- Elite endurance athletes, mountaineers.
- Good If Combined With
- Hypoxicator machines, stationary bikes.
- Source / Origin
- Soviet/Western Sports Science (1990s)
- Intensity & Safety
- High. Requires clinical equipment and supervision.
