چکیده
مقدمه و هدف: پایش ورزشکاران دارای اهمیت بالایی است چرا که برای مدیریت خستگی و عملکرد ورزشکاران ضروری است. هدف این پژوهش بررسی امکان استفاده از تکرار ذخیره برای پایش و کنترل خستگی هنگام اجرا تمرین مقاومتی می‌باشد.
مواد و روش‌ها: 11 آزمودنی مرد (1.14 ± 22.82 سال) باسابقه تمرینی حداقل یکسال کار با وزنه به‌صورت داوطلبانه در طی دو جلسه آزمون حداکثر یک تکرار بیشینه و حداکثر تکرار تا ناتوانی با فاصله 72 ساعت شرکت کردند. میانگین سرعت اجرای هر تکرار پرس­ سینه تا ناتوانی با سرعت 240 فریم بر ثانیه (240fps) فیلم­ برداری گردید. همبستگی میان کاهش سرعت و تکرار ذخیره با استفاده از آزمون همبستگی پیرسون با سطح معناداری (0.05>P) بررسی شد. همچنین دامنه تغییرات میزان تکرار ذخیره به ازای 10 درصد کاهش سرعت برای بررسی امکان استفاده کاربردی بررسی شد.
یافته‌ها: همبستگی قوی میان کاهش سرعت و تکرار ذخیره وجود داشت (0.97=r)، دامنه تغییرات تکرار ذخیره به ازای 10 درصد کاهش سرعت برابر 4 بین اعداد 7 و 3 تکرار ذخیره بود.
بحث و نتیجه‌گیری: به نظر می‌رسد علیرغم همبستگی بالای میان کاهش میانگین سرعت و تکرار ذخیره، امکان استفاده از تکرار ذخیره برای پایش و کنترل خستگی به علت دامنه گسترده تکرار ذخیره درازای مقدار ثابتی از کاهش سرعت (10 درصد) ممکن نیست.

چکیده English

Introduction and Purpose: Monitoring athletes is important for the management of fatigue and performance. This study was to investigate the possibility of using repetition in reserve for monitoring and controlling fatigue during resistance training.
Materials and Methods: 11 male subjects (22.82±1.1422 years) with at least one year of training experience participated voluntarily in two separate test sessions with a time interval of 72 hours. In the first session, the Participant asked for 1 repetition maximum test (1RM). In the next session, they conducted the maximum number of repetitions (MNR), also the velocity of each repetition is recorded at the speed of 240 frames per second (240 fps). Finally, the correlation between velocity loss and repetition in reserve was evaluated using the Pearson correlation test with a significance level (P<0.05). However, the range of changes in repetition in reserve at 10% of the velocity loss was checked to examine the possibility of practical use.
Results: There was a strong correlation between velocity loss and repetition in reserve (r=0.97), the range of repetition in reserve equal to 10% of velocity loss was equal to 4, the maximum repetition in reserve was 7 and the minimum was 3.
Discussion and Conclusion: Despite the strong correlation between velocity loss and repetition in reserve, it is not possible to use repetition in reserve for control and monitoring of fatigue due to the wide range of reserve repetition along with a fixed amount of velocity loss (10%).
