چکیده

هدف:  هیپوکسی و هیپوکاپنیا در انسان می ­تواند باعث انقباض برونش شده و عملکرد فرد را در ارتفاع بالا تحت تأثیر قرار دهد. این امر می­ تواند در افراد غیر­بومی و کوهنوردان غیرحرفه ­ای مشکل آفرین باشد. هدف تحقیق حاضر تاثیر یک هفته اقامت در ارتفاع 3600 متر بالاتر از سطح دریا بر شاخص ­های ریوی مردان کوهنورد غیر­حرفه ­ای بود. روش­ شناسی: در این پژوهش نیمه تجربی، 10 کوهنورد از امدادگران جمعیت هلال احمر اردبیل با میانگین سنی ( 78/4 ± 6/28 ) سال شرکت کردند. شاخص­ های عملکرد ریوی، فشار خون و ضربان قلب در سطح مبنای 1400 متری، پس از صعود به ارتفاع 3600 متری و پس از یک هفته اقامت در ارتفاع اندازه­گیری شدند. داده­­ها با استفاده از آزمون تحلیل کواریانس با اندازه­گیری تکراری در سطح معنی­داری 05/0>P مورد بررسی قرار گرفت. یافته ­ها: نتایج تحقیق حاضر نشان داد حداکثر جریان بازدمی PEF (04/0 =p) و فشار خون (022/0=p) پس از صعود و یک هفته اقامت در ارتفاع 3600متری به طور معنی ­داری کاهش یافتند. همچنین  FEV1/FVC پس از صعود به ارتفاع بالا افزایش معنی­ داری داشت (04/0=p). تغییر معنی ­داری در سایر شاخص­ های اندازه ­گیری شده مشاهده نشد (05/0

چکیده [English]

Aim: 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. Methodology: 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. Conclusion: 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.
