چکیده
مقدمه و هدف: هدف پژوهش حاضر مقایسه تأثیر تمرین باندهای الاستیک در وضعیت­ های افقی و عمودی بدن بر فشار خون پس از ورزش در زنان چاق بود.
مواد و روش ­ها: تعداد 13 زن چاق (سن: 8.33±37 سال و شاخص توده بدنی 2.84±31.75 کیلوگرم بر متر مربع) در این مطالعه با طرح متقاطع شرکت کردند. آزمودنی­ ها در دو پروتکل فعالیت ورزشی مقاومتی در وضعیت افقی و وضعیت عمودی با استفاده از باند الاستیک که متشکل از حرکات معمول بالاتنه و پایین تنه بود، شرکت کردند. پاسخ‌های همودینامیک قبل، 30 و 60 دقیقه پس از فعالیت ورزشی ثبت و از طریق آزمون تحلیل واریانس با اندازه­ گیری مکرر آنالیز شدند.
یافته­ ها: فشار خون سیستولیک (SBP) و فشار متوسط ​​شریانی (MAP)  30 دقیقه پس از فعالیت ورزشی افقی در مقایسه با قبل از فعالیت پایین‌تر بود. SBP نیز 30 دقیقه پس از فعالیت ورزشی افقی در مقایسه با 60 دقیقه پس از فعالیت ورزشی افقی کمتر بود (0.05>P). ضربان قلب (HR) 30 دقیقه پس از فعالیت ورزشی عمودی در مقایسه با قبل و 60 دقیقه پس از فعالیت ورزشی عمودی به طور قابل توجهی بالاتر بود (0.05>P).
بحث و نتیجه‌گیری: یک جلسه تمرین فعالیت ورزشی افقی می‌تواند SBP و MAP را در زنان چاق کاهش دهد. یافته­ های ما نشان می دهد که فعالیت ورزشی افقی ممکن است اثر مفید قلبی عروقی داشته باشد. علاوه بر این، بار مکانیکی کمتر و فشار کمتر روی مفاصل و ستون فقرات در طول فعالیت ورزشی افقی احتمالاً می ­تواند ظرفیت ورزشی را در افراد چاق بهبود بخشد.

Introduction and aim: The purpose of this study was to compare the effect of elastic band training in supine and upright body positions on post exercise hypotension (PEH) in obese women. Materials and methods: 13 obese women (age: 37±8.33 years and body mass index 31.75±2.84 kg/m2) participated in this study with a crossover design. Subjects participated in two protocols of resistance exercise in supine position and upright position using an elastic band that consisted of the usual movements of the upper and lower body. Hemodynamic responses were recorded before, 30, and 60 minutes after exercise and were analyzed using ANOVA repeated measures test. Results: Systolic blood pressure (SBP) and mean arterial pressure (MAP) were lower 30 minutes after supine exercise compared to before. SBP was also lower 30 minutes after supine exercise compared to 60 minutes after supine exercise (P≤0.05). Heart rate (HR) was significantly higher 30 minutes after upright exercise compared to before and 60 minutes after vertical exercise (P≤0.05). Conclusion: A session of supine exercise training could reduce SBP and MAP in obese women. Our findings show that supine exercise training may have a beneficial cardiovascular effect. In addition, less mechanical load and less pressure on joints and spine during horizontal exercise activity can improve exercise capacity in obese people.
