A LTITUDE TRAINING
Exercising at altitude ā usually over 2,500m (8,000ft) above sea level ā creates useful adaptations to working muscles. These make runners more efficient at both sea level and altitude, by increasing the concentration of red blood cells, which helps to boost endurance and speed.
You can travel to the mountains and train at altitude for two weeks to a month, or you can visit a hypoxic chamber, like the one at The Altitude Centre in Trump Street, London (altitudecentre.com). Training in these conditions not only prepares people for the rigours of altitude, but helps those with little time to train.
Sessions in the chamber are usually short, as most benefit is gained from high-intensity intervals, such as 10 x 1-minute fast, with a 1-minute recovery. Oxygen-deprived intervalsā¦
