Ensieh Yazdkhasti Department of Physical Education &amp;amp;amp; Sport Science, University of Mohaghegh Ardabili, Ardabil, Iran Journal Article 2021 08 25 <strong>Aim:</strong> Both hypoxia and hypocapnia can cause broncho-constriction in humans, and this could have a bearing on performance at high altitude. This can be a problem for non-natives and non-professional climbers. The purpose of this study was to investigate the effect of one-week stay at a height above 3600 m of sea level on the pulmonary indexes of men non-professional climber. <strong>Methodology:</strong> Ten non-professional climbers from Ardabil Red Crescent Society (with an average age of 28.6±4.78) voluntarily participated in this semi-experimental study. Pulmonary function indices, blood pressure and heart rate were measured at the baseline level of 1400 m, after climbing to an altitude of 3600 m and then after a week of staying at an altitude. Data were analyzed using analysis of covariance with repeated measures at a significance level of P<0.05. <strong>Conclusion:</strong> These findings might underlie “live high” strategy prescription for ergogenic aids as well as hypertension control.  However, more firm conclusion warrants to be verified in future studies. <strong>Aim:</strong> Both hypoxia and hypocapnia can cause broncho-constriction in humans, and this could have a bearing on performance at high altitude.
