Speaker's profile – DDr. Martin Burtscher
DDr. Martin Burtscher is a general practitioner, biologist and sports scientist, a certified skiing instructor and mountain as well as skiing guide. He is also vice-president of the Austrian Society for Mountain and High Altitude Medicine and scientific director of the Austrian Alpine Safety Board.
At the IMS:
Endurance capacity is one of the main criteria in successful high-altitude mountaineering. It is conditioned by three factors both at increased heights and in the valley:
1) the body's maximum oxygen absorption capacity (VO2max),
2) endurance limits (%VO2max) and
3) economy of motion.
From 1,500 m onwards, our body's maximum oxygen absorption capacity decreases by approximately 10% per 1,000 m of altitude gained. It remains at a reduced level during the acclimatisation period. The mountaineer's endurance limits, however, improve. Economy of motion refers to the amount of oxygen used for a certain activity and is strongly linked to years of adaptation to mountain sports at high altitudes.
Whereas, in the valley, the endurance capacity of a trained athlete is primarily limited by the maximum volume of cardiac output, at extreme heights the athlete's performance is conditioned by their lungs' diffusion capacity as well as ventilatory efficiency and capacity, as mountaineers with outstanding performance levels at high altitudes have demonstrated impressively. These characteristics may only be partly improved by training and can be assessed in sports medicine research laboratories.
