[Amphetamine doping in leisure-time mountain climbing at a medium altitude in the Alps].

Although doping in leisure sports may potentially be of relevance for medical emergency situations, it has attracted much less attention than doping in elite athletes. The aim of our study was to evaluate the prevalence of amphetamine consumption in medium altitude mountaineering. Urine samples were taken from 253 males after a successful ascent. Analysis for amphetamines proved positive for 7.1% of mountaineers climbing above 3300 m. On peaks between 2500 to 3300 meters above sea level, 2.7% of the mountaineers we examined had amphetamines residues in their urine. Below 2500 meters, no positive sample was detected. For tourists living outside of the Alpine range, we noticed a significantly higher proportion of positive analyses. We conclude that attempts to induce a higher performance level by pharmacological means are not overly uncommon in leisure mountaineering. Such a behaviour may be of medical relevance in emergency situations.
