چکیده

هدف: ایمپالس اوسیلومتر به عنوان روشی غیرمستقیم در ارزیابی تغییرات راه­های تنفسی ناشی از ورزش، در مقایسه با اسپیرومتر، کمتر مورد توجه قرار گرفته است. هدف مطالعه حاضر، مقایسه پاسخ راه­های هوائی به یک جلسه فعالیت ورزشی زیربیشینه در هوای معتدل و سرد  و رابطه داده­های ایمپالس اوسیلومتر با اسپیرومتر می­باشد. روش­شناسی : 18 مرد با فعالیت جسمانی طبیعی و شاخص توده بدنی کمتر یا مساوی 25 و مستعد برونکواسپاسم ناشی از ورزش ، برای این مطالعه انتخاب شدند. پروتکل تحقیق شامل 6 دقیقه فعالیت زیربیشینه با 80 تا 90 درصد حداکثر ضربان قلب، روی ترمیل و در هوای 4  و25 درجه سانتیگراد آزمایشگاه بود. برای مقایسه داده­های هوای سرد، به فاصله 48 ساعت، تست یکسان در هوای 22 درجه آزمایشگاه نیز از آزمودنی­ها بعمل آمد. نتایج: میان داده­های اسپیرومتریک و اوسیلومتریک فعالیت ورزشی در هوای سرد و معتدل، رابطه معناداری مشاهده شد. داده­های اسپیرومتری اختلاف معناداری را در مرحله پس از ورزش، در دو محیط سرد و معتدل نشان داد (p <0.05). اندازه­گیری مقاومت تنفسی توسط ایمپالس اوسیلومتر  اختلاف معناداری را در حداکثر کاهش شاخص راه­های هوائی در هردو محیط شناسائی کرد. بحث و نتیجه­گیری: رابطه معنادار میان داده­ها، کارآمدی اوسیلومتری در اندازه­گیری پاسخ راه­های هوائی به ورزش را نشان داد. نتایج نشان داد که هردو محیط می­توانند با مکانیسم مشترک بیش­پاسخی و خشک­شدن راه هوائی، باعث بروز برونکواسپاسم ناشی از ورزش شوند.

چکیده [English]

Purpose: The efficacy of impulse oscillometry as an indirect measure of exercise-induced airway changes, compared to spirometry has not been comprehensively appreciated. The objective was to compare airway responses to cold temperature exercise and to recognize whether impulse oscillometry parameters relate to spirometry parameters.Methods: 18 physically active men with probable Exercise-Induced Bronchospasm (Body Mass Index ≤25) were screened for this study. The exercise protocol was two 6-min sub-maximal exercises of running on the treadmill with 80-90% Peak Heart Rate in either cold (4.0 ◦C) or moderate (25.0 ◦C) temperature. 48 h was observed between these two challenges. Results: Strong correlations were found between cold and moderate temperature data for impulse oscillometry and spirometry. Spirometry revealed post-challenge significant difference in cold and moderate temperatures (p
