چکیده مقاله :
در سالهای اخیر مصرف نوشیدنیهای انرژیزا بخصوص در ورزشکاران رشد چشمگیری داشته است. ورزشکاران بر این باورند که مصرف نوشابههای انرژیزا بهعلت داشتن ترکیبات ارگوژنیکی مانند قندها، کافئین و تائورین عملکرد آنها را افزایش میدهند.لذا هدف پژوهش حاضر بررسی تاثیر نوشابه هایپ بر ادراک از فشار و خلق و خو در بسکتبالیستهای رده سنی 16 تا 18 سال بود. جامعه آماری پژوهش 60 نفراز دانش آموزان پسر مقطع متوسطه سال سوم هنرستان رشته تربیتبدنی شهرستان ملارد بودند که از این تعداد 24 داوطلب دانشآموز با وزن تقریبا یکسان (بین 68 تا 72کیلوگرم) انتخاب شدند. شرکتکنندگان بهشکل تصادفی در سه موقعیت؛ مصرف نوشابه هایپ 250 میلیلیتری با کافئین (32 میلیگرم در هر 100 میلیلیتر)، شرایط دارونما و پایه قرار گرفتند. مداخلات بهمدت 3هفته اعمال گردید. در تحقبق حاضر از آزمون والسیت برای ایجاد خستگی استفاده شد. سپس میزان درک از فشار از طریق شاخص بورگ و وضعیت خلق و خو بهوسیله پرسشنامه برومز در دو مرحله پیشآزمون و پسآزمون بررسی شد. نتایج آزمون فریدمن و تحلیل واریانس مکرر نشان داد مصرف نوشابه هایپ منجر به کاهش معنادار درک از فشار و خلق و خو در بسکتبالیستهای نوجوان شده است. در نتیجه نوشابه انرژیزا هایپ میتواند در کاهش ادراک از فشار و بهبود خلق و خو در بسکتبالیستهای نوجوانان موثر باشد. همچنین پژوهش حاضر نشان داد، تصور دریافت نیروزا (اثر دارونما)میتواند در کاهش درک از فشار و خلق و خو نیز موثر باشد.
In recent years the consumption of energy drinks has increased dramatically, especially among athletes. Athletes believe that consuming energy drinks increases their performance due to their ergogenic compounds such as sugars, caffeine and taurine. The age range was 16 to 18 years. The statistical population of the study was 60 male high school students in the third grade of the Malard School of Physical Education, out of which 24 volunteers with the same weight (between 68 and 72 kg) were selected. Participants were randomly assigned to three groups: consumption of 250 ml hype drinks with caffeine (32 mg per 100 ml), placebo and baseline conditions. Interventions were applied for 3 weeks. In the present study, Wall Sit test was used for fatigue. Then, perception of stress through Borg index and mood status was assessed by Broms Questionnaire in two stages of pretest and posttest. The results of Friedman test and repeated analysis of variance showed that consumption of hype drinks significantly reduced perception of stress and temperament in adolescent basketball players. As a result, energy drink hype can be effective in reducing perception of stress and improving mood in adolescent basketball players. The present study also showed that perception of placebo (effect of placebo) can be effective in reducing perception of stress and mood.
