چکیده مقاله :

هدف: جستجو برای دستیابی به یک ماده جادویی که موجب اعطای یک رده‌ی بالاتر رقابتی شود، همیشه مد نظر بوده است. هدف این پژوهش بررسی تأثیر هشت هفته تمرین قدرتی و مصرف مکمل کربوهیدرات بر چابکی، انعطاف‌پذیری، توان انفجاری و سرعت مردان بدنساز می‌باشد. روش‌ها: بدین منظور 36 مرد جوان بدنساز، داوطلب شرکت در تحقیق شدند و به طور تصادفی به سه گروه تجربی، دارونما و کنترل تقسیم شدند. آزمودنی‌های گروه تجربی مکمل کربوهیدرات و آزمودنی‌های گروه دارونما، دارونما مصرف کردند ولی گروه کنترل هیچ‌گونه مکملی را مصرف نکردند. آزمودنی‌های هر سه گروه به مدت 8 هفته، هفته‌ای 3 جلسه و هر جلسه به مدت 60 دقیقه تمرینات قدرتی منتخب با شدت 80-60 درصد یک تکرار بیشینه را انجام دادند. قبل و بعد از هشت هفته چابکی، انعطاف-پذیری، توان انفجاری و سرعت آزمودنی‌ها اندازه‌گیری شد. تجزیه و تحلیل داده‌ها با استفاده از نرم افزار spss و روش آماری تحلیل واریانس یک‌طرفه و آزمون تعقیبی بونفرونی انجام شد. یافته‌ها: نتایج تحقیق نشان داد که توان انفجاری بین گروه‌های تحقیق تفاوت آماری معنی‌داری دارد (019/0=p)، اما بین مقادیر چابکی، انعطاف‌پذیری و سرعت تفاوت معنی‌داری بین گروه‌ها مشاهده نگردید. نتیجه‌گیری: با توجه به نتایج تحقیق، می توان بیان کرد که تمرینات قدرتی همراه با مصرف مکمل کربوهیدرات باعث افزایش توان انفجاری می شود و پیشنهاد می شود که بدنسازان در کنار برنامه تمرینی خود از مکمل کربوهیدرات برای بهبود برخی از عوامل آمادگی جسمانی از جمله توان انفجاری خود استفاده کنند.

چکیده انگلیسی:

The search for a magical substance that will give it a higher competitive level has always been a concern. The aim of this study was to investigate the effect of eight weeks of strength training and carbohydrate supplementation on agility, flexibility, explosive power and speed of bodybuilding men. For this purpose, 36 young bodybuilders volunteered to participate in the study and were randomly divided into three experimental, placebo, and control groups. The experimental group received carbohydrate supplementation and the placebo group received placebo, but the control group did not take any supplement. Subjects in all three groups performed selected strength training with 60-80% of maximal repetition for 8 weeks, 3 sessions per week and 60 minutes each session. Agility, flexibility, explosive power and speed of subjects were measured before and after eight weeks. Data were analyzed by SPSS software and one-way ANOVA and Bonferroni post hoc test. Significant level was p≤0.05. The results showed that there was a statistically significant difference in explosive power between the groups (p = 0.019), but no significant differences were found between agility, flexibility, and speed. According to the results of the study, it can be stated that strength training combined with carbohydrate supplementation increases explosive power and it is recommended that bodybuilders, along with their exercise program, use carbohydrate supplements to improve some of their fitness factors, including their explosive power.
