چکیده

هدف این پژوهش بررسی تأثیر کم‌آبی خفیف بر توجه انتخابی و مداوم بود. پژوهش از نوع نیمه‌تجربی و بر روی 22 دانشجوی دختر (21/2 ± 23/21) انجام گرفت. آزمودنی‌ها به‌صورت در دسترس انتخاب و تحت سه شرایط پایه، پرآب و کم‌آب قرار گرفتند. شرکت‌کنندگان در حالت پایه، هیچ‌گونه فعالیت‌بدنی نداشتند اما در شرایط پرآب و کم‌آب برنامة 60 دقیقه‌ای پیاده‌روی بر روی تردمیل و دوچرخه‌ را اجرا نمودند. ابزارهای پژوهش شامل آزمون استروپ و عملکرد پیوسته نسخة چهار بودند که برای سنجش توجه‌انتخابی و ‌مداوم استفاده شدند. جهت تحلیل آماری از آزمون تحلیل واریانس با اندازه‌های تکراری استفاده گردید. یافته‌ها نشان داد میانگین نمرات توجه‌انتخابی و مداوم در حالت‌ پایه نسبت‌به کم‌آب و در حالت پرآب نسبت‌به کم‌آب به‌طور معناداری بهتر بود و کم‌آبی خفیف منجر به اختلال در توجه‌انتخابی و مداوم شد. لذا توجه به حالت هیدراتة مطلوب در زمان انجام فعالیت‌بدنی ضروری می‌باشد.

چکیده [English]

The study investigated effects of mild dehydration on selective and sustained attention. 22 female students participated in a quasi-experimental study. Convenience sampling was used and participants were assigned to three basic, hydration, and dehydration conditions, counterbalancelly. In the basic condition, they had no physical activity, but in hydration and dehydration conditions, they completed a 60-minute exercise protocol of walking on a treadmill and bicycling. Data were collected using Simple Stroop and Continuous Performance Test V.4. A significant main effect was found for exercise condition. No interaction was found for exercise condition and attention. In dehydrated condition, selective and sustained attention’s mean scores were higher than control and hydrated conditions (p<0.05). However, no significant difference (p>0.05) was found between selective and sustained attention’s mean scores in control and hydrated conditions. Accordingly, mild dehydration affected selective and sustained attention. Therefore, it seems necessary to consider optimal hydration during exercise .
