چکیده

زمینه و هدف: کافئین یکی از محبوب‌ترین و پرمصرف‌ترین نوشیدنی‌ها در جهان است. منبع اصلی آن به‌صورت طبیعی در دانه‌های قهوه است، اما در گیاهان دیگری مانند برگ چای نیز وجود دارد. غرغره کردن محلول کافئینی بدون بلعیدن، روش نوینی است که بدون عبور از دستگاه گوارش سبب بالا رفتن عملکرد بدنی و شناختی می‌شود. با توجه به در گیر بودن دستگاه هوازی و بی‌هوازی در ورزش کاراته، هدف از پژوهش حاضر، بررسی تأثیر غرغره کردن محلول کافئینی بر توان هوازی، بی‌هوازی و چابکی مردان کاراته‌کا بود.
مواد و روش‌ها: بدین‌منظور 12 مرد کاراته‌کا سطح باشگاهی با پیشینة تمرین دست‌کم دو سال به‌طور داوطلبانه در یک پژوهش متقاطع، متعادل، تصادفی و دوسو کور، بررسی شدند. آزمودنی‌ها سر ساعت 7:30 دقیقه صبح در محل سالن ورزشی به‌صورت ناشتا حضور پیدا کردند. پس از 10 دقیقه گرم کردن پویا شامل راه رفتن و حرکات کششی، آزمودنی‌ها محلول کافئینی (25 میلی‌لیتر آب همراه با 600 میلی‌گرم کافئین) یا دارونما (25 میلی‌لیتر آب خالی) را به مدت 20 ثانیه غرغره کردند. سپس آزمون ایلی نویز برای سنجش چابکی ورزشکار، آزمون رست برای سنجش توان بی‌هوازی، آزمون هوازی ویژة کاراته اجرا شد و در نهایت آزمون بورگ برای سنجش خستگی ورزشکار انجام شد. تجزیه‌وتحلیل آماری با استفاده از آزمون t زوجی و نرم‌افزار SPSS نسخة 24 گزارش شد.
نتایج: غرغره کردن محلول کافئینی در مقایسه با دارونما بهبود معناداری در چابکی (002/0=P)، شاخص خستگی (016/0=P) و مقیاس بورگ (021/0=P) در مردان کاراته‌کا ایجاد کرد. اما بر توان هوازی (167/0=P)، توان بی‌هوازی بیشینه (568/0=P)، دست‌کم توان بی‌هوازی (650/0=P) و حد متوسط توان بی‌هوازی (648/0=P) تأثیر معنادار نداشت.
نتیجه‌گیری: در نتیجه‌گیری کلی می‌توان گفت که غرغره کردن محلول کافئینی بر برخی شاخص‌های عملکردی کاراته‌کاها تأثیر مثبت دارد و با توجه به عوارض کمتر، مصرف آن پیشنهاد می‌شود.

چکیده [English]

Background and Purpose: Caffeine is one of the most popular and widely consumed beverages in the world. Its main source is naturally found in coffee, but it is also found in other plants such as tea leaves. Caffeine mouth rinse without swallowing is a new method that increases physical and cognitive performance without passing through the digestive tract. Considering the involvement of the aerobic and anaerobic systems in karate, the aim of the present study was to investigate the effect of caffeine mouth rinsing on aerobic capacity, anaerobic power, and agility in male karatekas.
Materials and Methods: For this purpose, 12 male club-level karatekas with at least two years of training experience were voluntarily studied in a crossover, balanced, randomized, and double-blind study. The subjects arrived at the gym at 7:30 am in a fasting state. After a 10-minute dynamic warm-up including walking and stretching, subjects rinsed their mouth for 20 seconds either with a caffeine solution (25 mL of water with 600 mg of caffeine) or a placebo (25 mL of empty water). Then, the Illinois test was performed to measure athlete agility, the RAST test to measure anaerobic power, the karate-specific aerobic test to measure aerobic capacity and finally the Borg test to measure athlete’s fatigue. Statistical analysis was carried out by using paired t-tests and SPSS software version 24.
Results: Rinsing with caffeine solution significantly improved agility (P=0.002), fatigue index (P=0.016), and Borg scale (P=0.021) in male karatekas compared to placebo. However, there was no significant effect on aerobic power (P=0.167), maximum anaerobic power (P=0.568), minimum anaerobic power (P=0.650), and average anaerobic power (P=0.648).
Conclusion: In general, it can be concluded that rinsing with caffeine solution has a positive effect on agility and fatigue markers in karatekas and considering its fewer side effects, it is recommended to be used in these athletes.
