We have selected a small sample of our research across sport, mountaineering and health which we hope you find of interest. Our team are happy to compile research on specific topics of altitude acclimatisation and hypoxic training upon request.
Hypoxic training and weight loss
New research suggests that mild physical exercise three times per week for 90 min in normobaric hypoxia for 8 weeks led to significantly greater weight loss in obese persons than the exercise in sham hypoxia (sea level).

Hypoxic training and strength
Current research suggests that resistance training under hypoxic conditions improves muscle strength and induces muscle hypertrophy faster than under normoxic conditions, thus representing a promising new training technique. In the hypoxic training group arm strength was increased significantly from baseline after only 3wks (p< 0.01).

Hypoxic training and endurance performance
Intermittent hypoxic training involving specific high-intensity and moderate- duration hypoxic sessions, is considered to maximise potential muscular adaptation in trained athletes, resulting in increased endurance performance capacity. Within this current study only the HYP training group achieved a significant increase in running time to exhaustion.

Hypoxic training and Acute Mountain Sickness
Acute mountain sickness (AMS) develops in non acclimatized mountaineers going to high altitudes. The incidence of AMS increases with altitude, and hypoxia is a major causative factor. Previous research suggests that when mountaineers ascend rapidly to 2,500 m, about 10% of them will suffer AMS, and when ascending to 4,500 m, the AMS incidence will exceed 60%, however individuals differ in their response to altitude. Therefore awareness of an individual’s susceptibility for AMS is helpful for correctly informing specific preventive strategies and hypoxic training programs.
