چکیده
مقدمه: ارزیابی مستقیم یک تکرار بیشینه (1RM) ورزشکاران نابینا به دلیل محدودیت‌های بینایی و خطرات مرتبط با آن چالش‌برانگیز است. به همین دلیل، شاخص درک فشار (RPE) به‌عنوان روشی ایمن‌تر و غیرمستقیم پیشنهاد شده است. هدف این مطالعه بررسی رابطه بین شاخص درک فشار و درصدهای مختلف 1RM در حرکت پرس سینه ورزشکاران نابینا بود.

روش پژوهش: در این مطالعه نیمه‌تجربی، ۴۳ ورزشکار نخبه نابینا (میانگین سنی 2/27 ± 5/5 سال؛ شاخص توده بدنی 5/25 ± 4/2 کیلوگرم بر مترمربع) در چهار رشته ورزشی (گلبال، فوتبال، دوومیدانی و شنا) در دسته‌های B1، B2 و B3 شرکت کردند. ابتدا 1RM برای هر ورزشکار به روش استاندارد ارزیابی شد و سپس شاخص RPE در درصدهای 40 تا 90 درصد 1RM با استفاده از مقیاس CR-10 تعیین گردید.

یافته‌ها: نتایج نشان داد که همبستگی مثبت و معناداری (r = 0.89) بین RPE و درصدهای مختلف 1RM وجود دارد. میانگین نمرات RPE در 40 درصد 1RM برابر 16/3، 50 درصد 13/4، 60 درصد 32/5، 70 درصد 85/6، 80 درصد 04/8 و در 90 درصد 05/9 بود.

نتیجه‌گیری: نتایج این مطالعه نشان می‌دهد که RPE می‌تواند به‌عنوان ابزاری ایمن و قابل اعتماد در برنامه‌ریزی تمرینات مقاومتی برای ورزشکاران نابینا، در کنار 1RM استفاده شود.

چکیده English

Introduction: Direct assessment of one-repetition maximum (1RM) in blind athletes presents challenges due to visual limitations and associated risks. Therefore, the rating of perceived exertion (RPE) has been suggested as a safer, indirect method. The aim of this study was to examine the relationship between RPE and different percentages of 1RM in the bench press exercise among blind athletes.

Methods: In this quasi-experimental study, 43 elite blind athletes (mean age 27.2 ± 5.5 years; BMI 25.5 ± 2.4 kg/m²) from four sports (goalball, football, athletics, and swimming) in B1, B2, and B3 categories participated. Initially, each athlete's 1RM was assessed using standard methods, and then the RPE was measured using the CR-10 scale at 40% to 90% of 1RM.

Results: The findings revealed a significant positive correlation (r = 0.89) between RPE and various percentages of 1RM. The mean RPE scores for 40%, 50%, 60%, 70%, 80%, and 90% of 1RM were 3.16, 4.13, 5.32, 6.85, 8.04, and 9.05, respectively.

Conclusion: These results suggest that RPE can be used as a safe and reliable tool alongside 1RM for resistance training programming in blind athletes.
