Lower oxygen at higher altitude and lack of acclimatisation can lead to Acute Mountain Sickness (AMS) and compromise your skiing ,trekking or climbing holiday. Acute AMS can strike as low as 2000m and many ski fields are up to 4000m. While AMS affects people in different ways, Altitude training can help reduce or buffer against the symptoms of AMS and reduce the time you need to spend acclimatising on site. You will also arrive fitter, stronger and better equipped to deal with the rigours of activity at altitude.
During a training session, the key metric to monitor altitude training progress is through intermittently measuring the amount of oxygen in our body (our blood oxygen saturation levels or SaO2 for short) using a pulse oximeter.
In order to stimulate the body to physiological adapt and to reap the benefits of altitude training, our blood oxygen saturation levels need to be between 80 – 85% (at sea-level our levels range from 95 – 100%).
