چکیده
پژوهش حاضر با هدف بررسی تأثیر 8 هفته تمرین مقاومتی توانی و مصرف مکمل کیوتن (10Q) بر میزان اینترلوکین-4 (4-IL) و 10-IL و فاکتورهای عملکردی بازیکنان سافتبال انجام گرفت. 20 نفر از بازیکنان دخترسافتبال (16/4±68/21 سال) به روش در دسترس انتخاب و بهطور تصادفی به دو گروه 10 نفرۀ تجربی (مصرف مکمل 10Q + تمرین مقاومتی توانی) و کنترل (دارونما + تمرین مقاومتی توانی) تقسیم شدند. مداخله شامل 8 هفته مصرف مکمل 10Q (یک کپسول 200 میلیگرمی) و تمرینات مقاومتی توانی با تواتر 2 جلسه در هفته و به مدت 8 هفته (10 دقیقه گرم کردن، 45-40 دقیقه تمرینات اصلی مقاومتی با شدت 60 تا 70 درصد یک تکرار بیشینه و 10 دقیقه سرد کردن ) بود. آزمون چابکی تی، تست سرعت دوی 60 متر، پرش سارجنت، دراز و نشست و قدرت پنجۀ دست، همچنین نمونهگیری خونی قبل و بعد از 8 هفته فاکتورهای 10-IL،4-IL، CK و LDH ارزیابی شدند. دادهها با استفاده از تی مستقل و تی همبسته در سطح معناداری 05/0>P تحلیل شدند.رکوردهای سرعت (تجربی 04/0=P؛ کنترل 02/0=P)، چابکی (تجربی 03/0=P؛ کنترل 03/0=P)، قدرت پنجۀ دست (تجربی 009/0=P؛ کنترل 01/0=P)، دراز و نشست (تجربی 001/0=P؛ کنترل 003/0=P) و میزان لاکتات دهیدروژناز (تجربی 03/0=P؛ کنترل 03/0=P) بهطور معناداری در هر دو گروه بهبود یافت؛ اما عملکرد پرش سارجنت (تجربی 10/0=P؛ کنترل 89/0=P)، میزان کراتین کیناز (تجربی 67/0=P؛ کنترل 06/0=P)، 4-IL (تجربی 32/0=P؛ کنترل 33/0=P) و 10-IL (تجربی 97/0=P؛ کنترل 08/0=P) در هیچکدام از دو گروه تغییر معناداری نداشت. نتایج نشان داد بهنظر میرسد تمرینات مقاومتی توانی بههمراه مکملدهی کوآنزیم 10Q در کنار تمرینات تخصصی سافتبال بهمنظور توسعۀ برخی متغیرهای عملکردی بهویژه استقامت عضلانی ناحیۀ شکم مؤثر است.

چکیده [English]
Aim: The current study was aimed to investigate the effect of eight weeks of resistance training and coenzyme Q10 supplement on interleukin 4 and 10 levels and functional indices of skilled softball players.
Methodology: Twenty females Softball players from Isfahan were selected by available sampling method and randomly assigned into two groups of 10 players (experimental group; Q10 + resistance training) and (control group; placebo + resistance training). The intervention consisted of eight weeks of Q10 supplementation (a 200 mg capsule) and 2 sessions per week of resistance training along with specialized softball exercises. Before and after the 8-week intervention, agility, speed, vertical jump, sit-ups, and hand-grip power were evaluated, as well as the blood sampling was obtained from athletes
Results: Speed (P = 0.04 experimental; P = 0.02 control), agility (P = 0.03 experimental; P = 0.03 control), hand-grip power (P = 0.009 experimental; P = 0.01 control), sit-ups (P = 0.001 experimental; P = 0.003 control) and lactate dehydrogenase levels (P = 0.03 experimental; P = 0.03 control) significantly improved in both groups; however, Sargent's jump (P = 0.10 experimental; P = 0.89 control), creatine kinase (P = 0.67 experimental; P = 0.66 control), interleukin-4 (P = 0.32 experimental; P = 0.33 control) and interleukin-10 (P = 0.97 experimental; P = 0.08 control) did not alter in either group.
Conclusion: It appears that resistance training with Q10 supplementation along with specialized softball exercises is useful in developing some functional variables, especially abdominal endurance.
