چکیده

مقدمه و اهداف
تحقیقات نشان می­دهد که انقباض آیزوکینتیک فشار بیشتری را در طول دامنه حرکت وارد می­کند و نوع آن نیز می­تواند بر پاسخ سیستم­های بدن موثر باشد؛ لذا هدف از مطالعه حاضر مقایسه پاسخ شاخص­های پلاکتی به انقباض­های برونگرا و درونگرای آیزوکینتیک در مردان بود.
مواد و روش­ها
پژوهش حاضر از نوع نیمه­تجربی با آزمون مکرر بود که تعداد 10 آزمودنی مرد (9/1± 2/24 سال) داوطلبانه در 3 جلسه مجزا به آزمایشگاه دعوت شدند. جلسه اول آشناسازی با پروتکل وجلسات دوم و سوم به صورت توازن متقابل 4 ست 10 تکراری پروتکل­های کانسنتریک/کانسنتریک[1]و ایسنتریک/ ایسنتریک[2] را با 60 ثانیه استراحت بین ست­ها اجرا کردند. شاخص­های پلاکتی شامل تعداد پلاکت­ها (PLT)[3]، درصد پلاکتی (PCT)[4]، میانگین حجم پلاکتی (MPV)[5] و پهنای توزیع پلاکتی (PDW)[6] قبل و در دقایق 0، 15، 30، 45 و60 دوره­ی ریکاوری اندازه­گیری شد. آنالیز آماری داده­ها با استفاده از واریانس مکرر (6×2) انجام شد.
یافته ها
نوع انقباض تاثیر معناداری بر PLTو PDW نداشت (05/0P>)، اما تاثیر خود فعالیت آیزوکینتیک بر این دو فاکتور معنادار بود (05/0P<). نه نوع انقباض و نه فعالیت آیزوکینتیک تاثیر معناداری برMPV نداشت (05/0P>). در حالی که هردوی فعالیت آیزوکینتیک و نوع انقباض عضلانی اثر معناداری بر PCT داشتند (05/0P<).
نتیجه­ گیری
بر اساس یافته­های تحقیق حاضر می­توان نتیجه­گیری گرفت که فعالیت آیزوکینتیک بر شاخص­های پلاکتی موثر می­باشد و علت عدم تفاوت در تاثیرگذاری دو نوع پروتکل احتمالا به دلیل یکسان بودن میزان بار کار آنها می­باشد.

چکیده [English]

Background and Aim: The previous investigations have showed that isokinetic contractions lead to more pressure on muscles over full range of motion. Also, the type of isokinetic contractions can determine body response. The aim of the present study was to compare the responses of platelet indices to concentric and eccentric isokinetic contractions in men.
Materials and Methods: A total of 10 healthy male individuals (age, 24.2±1.99) voluntarily participated in the study and were invited to laboratory at three separate occasions. The first session was designed for familiarizing the participants with laboratory environment and measuring the anthropometrical characteristics. In the 2nd and the 3rd sessions, participants performed two exercise protocols in a counterbalance manner comprising of four sets of 10 repetitions of CON/CON and ECC/ECC isokinetic contractions in the knee joint with 60s rest between sets. Blood platelet indices including platelet count were measured before and at 0, 15, 30, 45, and 60 minutes after exercise. Data was analyzed using repeated measures of ANOVA (2×6).
Results: Contraction type had no significant effect on PLT and PDW (p>0.05), though, irrespective of the type of contraction, isokinetic exercise had a significant effect (P<0.05). Neither type of contraction nor isokinetic exercise had significant effects on MPV (P>0.05). However, both types of contraction and isokinetic exercise had significant effects on PCT (P>0.05).
Conclusion: Based on the findings of the present study, it is concluded that isokinetic exercise, irrespective of its type (CON or ECC), is effective on platelet indices and that lack of differences between the two contractions types might be due to equality of exercise load.
