چکیده

مقدمه: این پژوهش باهدف بررسی تأثیر تمرینات دو قطبی یا پلاریزه بر طول شاخص‌های نوار قلب یعنی 1- دامنه موج P2-دامنه موجT 3- مدت‌زمان کمپلس QRS 4-مدت‌زمان بازه‌ی قطعه RR 5-مدت‌زمان قطعه QT6-مدت‌زمان‌قطعهPR 7-مدت‌زمان قطعه ST در دختران جوان فعال انجام شد. روش کار: در این پژوهش، 20 دختر جوان با میانگین سنی 57/1±8/22 و شاخص توده بدنی 8/2±26/22 کیلوگرم برمجذور قد که ازنظر فعالیت بدنی فعال بودند و سابقه انجام ورزش های استقامتی مانند والیبال ،هندبال ،شنا و...و تمرینات بدنسازی را داشتند. در یک طرح هدفمندانتخاب و به صورت تصادفی به دو گروه 10 نفره کنترل وتمرین پلاریزه تقسیم شدند. شرکت کنندگان در تمرین پلاریزه به مدت هشت هفته، سه بار در هفته و هر جلسه به مدت 12دقیقه به تمرینات پلاریزه 3به1 پرداختند(3دقیقه با 70%و1دقیقه با 90%ضربان قلب بیشینه). الکتروکاردیوگرام آزمودنی‌ها، 24 ساعت پیش از شروع پروتکل تمرینی 8 هفته‌ای و 24 ساعت پس از اتمام آن، ثبت گردیدو با استفاده از آزمون تی همبسته برای مقایسه میانگین دو پروتکل تمرینی مورد تحلیل قرار گرفت. سطح معنی‌داری در تمام تحلیل‌ها 05/0 در نظر گرفته شد. نتایج: نتایج نشان داد که طول شاخص های مد نظر به‌طور معناداری پس از تمرین پلاریزه افزایش‌یافته است. (05/ 0 P<) نتیجه گیری: این یافته‌ها حاکی از آن است که تمرین تمرینات پلاریزه می‌تواند این پروتکل تمرینی 8 هفته‌ای، اثرات مثبت و از لحاظ آماری معناداری بر شاخص‌های سلامت قلبی-عروقی در دوره زمانی کوتاه مطالعه، به نمایش گذاشت.

چکیده [English]

Introduction: This study was designed to investigate the effect of polarized exercises on the duration of important electrocardiographic indicators in active young girls. The indicators of interest include 1) P wave amplitude, 2) T wave amplitude, 3) QRS complex duration, 4) RR segment interval duration, 5) QT interval duration, 6) PR segment duration, and 7) ST segment duration.
Materials and Methods: twenty healthy young women (Age 22.8±1.57 years; BMI 22.26±2.8kg/m²) were recruited for this study using a purposive sampling technique. All participants were characterized as physically active, reporting a sustained history of participation in competitive endurance sports, including volleyball, and ..., in addition to regular experience with resistance trainings . Following baseline assessments, the subjects were randomly divided into two experimental groups (n=10 n=10 per group) for the subsequent intervention phase. control and polarized exercise. Participants in the POL training performed 3:1 POL training (3 minutes at 70% and 1 minute at 90% of maximum heart rate) for 8 weeks, 3 times a week, and each session lasting 12 minutes. The subjects' ECGs were taken one day before the start of the test and after the end of the test and analyzed using a paired t-test to compare the means of the training protocols. The significance level in all analyses was considered to be 0.05.
Results: Indicators significantly improved/increased following polarized training(P<0.05).
Conclusion: These results suggest that the (POL) model, as implemented over the 8-weeks protocol, successfully induced positive and statistically significant improvements in the measured cardiovascular health parameters.
