چکیده
مقدمه

تغییرات و عدم تعادل در سیستم هموستاز، یکی از علل اصلی حملات قلبی است. اطلاعات ناهمسویی درباره تاثیر انواع تمرین ورزشی به ویژه تمرینات مقاومتی بر فاکتورهای انعقادی وجود دارد. هدف از مطالعه حاضر بررسی اثر 8 هفته تمرین مقاومتی چند مفصله و تک مفصله بر برخی فاکتورهای انعقادی و خونی مردان جوان فعال بود.

مواد و روش‌‌ها

30 آزمودنی‌ (20-26 سال) با آرایش تصادفی در گروه‌‌های کنترل (10n=)، تمرین مقاومتی تک مفصله (10n=) و تمرین مقاومتی چند مفصله (10n=) توزیع شدند. گروه‌‌های تجربی به مدت 8 هفته و هر هفته 3 جلسه پروتکل‌‌های تمرینی مخصوص را انجام دادند. برای تعیین طبیعی بودن داده‌‌ها از آزمون شاپیروویلک و جهت محاسبه مقادیر تغییرات در دو پروتکل از آزمون تحلیل کوواریانس و در صورت معنی‌‌دار بودن از آزمون تعقیبی بونفرونی استفاده شد.

یافته‌‌ها

تمرین مقاومتی تک مفصله و چند مفصله تاثیر معنی‌‌داری بر تعداد پلاکت‌‌ها داشته است (0/001>p). نوع پروتکل و تمرین مقاومتی تاثیر معنی‌‌داری بر پهنای توزیع پلاکتی نداشته است (0/34=P). براساس یافته‌‌ها می‌‌توان گفت هر دو نوع تمرین، تاثیر معنی‌‌داری بر هماتوکریت و سدیمانتاسیون گلبول قرمز داشته است (=0/001P) و بطور کلی تاثیر فعالیت مقاومتی صرف نظر از نوع آن بر هماتوکریت و سدیمانتاسیون گلبول قرمز موثر بود (0/003=P و 0/001>p).

نتیجه‌‌گیری

8 هفته تمرین مقاومتی باعث کاهش سطح تعداد پلاکت‌‌ها و همچنین کاهش هماتوکریت و کاهش سدیمانتاسیون گلبول قرمز می‌‌شود که نشان دهنده کاهش احتمال خطرات قلبی‌‌-‌‌عروقی حین اجرای فعالیت‌‌های ورزشی است.

Introduction

The alterations and imbalances in homeostasis are one of the main causes of heart attack. Th8ere is a discrepancy about the effects of various types of exercise, exercises, especially resistance exercises on coagulation factors. The objective of this study was to examine the effect of 8 weeks single joint and multiple joint resistance training on some coagulation and blood factors of active young men.

Materials and Methods

30 subjects (20-26 years) were selected with randomly distributed in control group (n=10), single joint resistance training (n=10), and multi-joint resistance training (n=10). The experimental groups performed protocols for 8 weeks, three sessions each week. The Shapiro-Wilk test was used to determine the normality of the data and the differences were compared using the Ancova test and if significant results were reached, Bonferroni test was used.

Results

The single joint and multi-joint resistance training group had a significant effect on platelet (P<0.001). The type of protocol and resistance training did not have a significant effect on Platelet cell distribution Width (P=0.34). According to the findings, it can be said that both types of training had a significant effect on hematocrit and Erythrocyte Sedimentation (P=0.001), and in general, the effect of resistance training, regardless of its type, was effective on hematocrit and erythrocyte sedimentation (P=0.003, P<0.001).

Conclusion

The 8 weeks of resistance training reduces the number of platelets and also decreases hematocrit and reduces the blood sedimentation, which indicates a reduction in the risk of cardiovascular attacks while exercising.
