چکیده

از کامپلیانس و ضخامت اینتیما-مدیای شریان کاروتید به‌عنوان شاخص­هایی تعیین‌کننده برای تشخیص مشکلات قلبی-عروقی نام برده می­شود که تحت‌تأثیر عواملی چون سن، فعالیت بدنی و غیره قرار می­گیرند؛ بنابراین، هدف از انجام مطالعة حاضر، مقایسة ویژگی­های مکانیکی خون و شریان کاروتید بسکتبالیست­های حرفه­ای و افراد غیرفعال بود. با استفاده از دستگاه سونوگرافی داپلر، فیلم و تصویر از شریان کاروتید سمت راست 10 مرد جوان بسکتبالیست و 10 مرد جوان غیرورزشکار تهیه شد و باهم مقایسه شدند. نتایج نشان داد که بسکتبالیست­ها نسبت به گروه غیرورزشکار تعداد ضربان قلب کمتر(8/15%) و ضخامت اینتیما-مدیا در مرحلة دیاستول بیشتر (8/17%) داشتند، اما سرعت جریان خون در مرحلة سیستول (6/18%)، دیاستول(7/26%) و کامپلیانس (32%) در گروه غیرورزشکار بیشتر بود.با توجه به یافته­های پژوهش، به‌نظر می­رسد افزایش سفتی شریان در بسکتبالیست­ها می­تواند سازگاری فیزیولوژیک با افزایش فشار خون درطی تمرین و مسابقه‌ها باشد.

چکیده [English]

Compliance and Carotid artery intima-media thickness are both important determinants of cardiovascular problems that are influenced by factors such as age, physical activity, etc. Therefore, the aim of this study was to compare blood mechanical properties and the carotid artery of professional basketball players and inactive people. For this purpose 10 young basketball men were compared with 10 young non-athlete men. Using the Doppler ultrasound apparatus, the film and image of the right carotid artery was taken from the subjects. Results showed that basketball players had lower heart rate (↓15.8%) and higher intima-media thickness in diastolic phase (↑17.8%) than non-athlete group, but systolic blood velocity (↑18.6%) and diastolic blood velocity (↑26.7%) and compliance (↑32%) were higher in the non-athlete group. Increased arterial stiffness in basketball seems to be a physiological adaptation to hypertension during training and competitions.
