| سابقه و هدف: روش ژئومتریکی دینامیک غیرخطی بررسی تغییرپذیری ضربان قلب نسبت به روشهای خطی از قبیل روش زمان محور و فرکانس محور تغییرپذیری ضربان قلب اطلاعات ارزشمندی از ساختار پاسخپذیری سیستم اتونوم قلبی ارائه مینماید. هدف از این پژوهش، بررسی اثر یک دوره متوالی فعالیت ورزشی هوازی بر تغییرپذیری ضربان قلب با استفاده از روش غیرخطی احتمال تکرار توالیهای هم شکل در مردان جوان دانشگاهی میباشد. مواد و روشها:28 مرد جوان دانشگاهی به طور تصادفی در گروههای پژوهش( گروه کنترل؛ گروه تمرین هوازی) تقسیمبندی گردیدند. در دوره پیش آزمون و بعد از مداخله تمرین هوازی، تمامی پارامترهای تغییرپذیری ضربان قلب با روش زمانی و توالیهای ضربان قلب اندازهگیری گردید. سپس انحراف معیار توالیهای ثبت شده با استفاده از روشPoincare plotتفسیر گردید. به منظور مقایسه تفاوتها در مراحل پژوهش، از آزمونهای تی مستقل و همبسته استفاده گردید. یافته ها:انحراف معیار آنی اینتروال ضربه به ضربه تغییرپذیری ضربان قلب(SD1) نسبت به گروه کنترل(01/0=p) و پیش آزمون(01/0=p) و انحراف معیار مداوم اینتروال ضربه به ضربه تغییرپذیری ضربان قلب(SD2) نسبت به گروه کنترل(01/0=p) و پیش آزمون(02/0=p) افزایش معنیداریداشت.بعد از تبدیل به حالت نرمال SD1nنسبت به گروه کنترل(02/0=p)افزایش معنیدار و نسبت به پیش آزمون(08/0=p) افزایش غیرمعنیداری داشت،SD2nنسبت به گروه کنترل(04/0=p) افزایش معنیدارو نسبت به پیش آزمون(02/0=p) افزایش غیرمعنیداری داشت. مقایسه نسبت انحراف معیار آنی به انحراف معیار مداوم(SD2/SD1) نسبت به گروه کنترل و پیش آزمون تفاوت معنیداری را نشان نداد. نتیجه گیری:اجرای منظم و مداوم فعالیت ورزشی هوازی با شدت متوسط سبب بهبود پاسخپذیری عصبی قلبی در مردان جوان دانشگاهی میگردد. | ||

| Background and Purpose: Nonlinear dynamic geometric methods of heart rate variability over linear methods such as time and frequency-domain provides valuable information about the response of the cardiac autonomic system. The aim of this study was to investigate the effect of a consecutive course of aerobic exercise on heart rate variability using a nonlinear method with the possibility of repeating similar sequences of heart rate in young college men. Methodology: 28 young college men were randomly divided into research groups (control group; aerobic exercise group). In the pre-test period and after the aerobic exercise intervention, all parameters of heart rate variability were measured by time-domain method and heart rate sequences. The standard deviation of the recorded sequences was then interpreted using the Poincare plot method. In order to compare the differences in the research stages, independent and paired t-tests were used. Results: Immediate interval standard deviation of heart rate variability (SD1) increased significantly compare to the control group (p = 0.01) and pretest (p = 0.01) and continuous interval standard deviation of heart rate variable (SD2) increased significantly compared to the control group (p = 0.01) and pre-test (p = 0.02). After conversion to normal, SD1n compared to the control group (p = 0.02) increased significantly and There was a non-significance increases compared to the pre-test (p = 0.08), SD2n had a significant increase compared to the control group (p = 0.04) and a significant increase compared to the pre-test (p = 0.02). Comparing the ratio of the instantaneous standard deviation to the continuous standard deviation (SD1 / SD2) with respect to the control and pretest groups did not show a significant difference (p≥0.05). Conclusion: Regular and continuous performance of moderate-intensity aerobic exercise improves cardiac neuroresponsibility in young college men. | ||
