چکیده

مقدمه و اهداف
امروزه انجام تمرینات معلق، به‌ عنوان یک شیوه‌ مؤثر در بهبود ثبات مرکزی در افراد سالم و افراد دارای ناهنجاری‌های اسکلتی-عضلانی مطرح شده است؛ بااین‌وجود، فعالیت عضلات مختلف ناحیه مرکزی بدن در تمرینات مختلف به شیوه معلق، مورد بررسی قرار نگرفته است؛ بنابراین، هدف از انجام تحقیق حاضر، مقایسه‌ فعالیت الکتریکی عضلات منتخب ناحیه‌ مرکزی بدن حین اجرای تمرینات منتخب ثبات مرکزی به روش تی‌آر‌ایکس بود.
مواد و روش­ ها
در پژوهش حاضر، 15 دانشجوی زن فعال سالم شرکت نمودند. هر آزمودنی، حرکت‌های پل، پلانک و لانگ را در حالت قرارگیری پا داخل طناب تی‌آر‌ایکس و به ‌صورت سه تکرار پنج ‌ثانیه‌ای انجام داد و به ‌طور‌ هم‌زمان فعالیت عضلات راست شکمی، خارجی شکمی، راست­ کننده‌ی ‌ستون ‌مهره‌ها و چند‌سر کمری توسط دستگاه الکترومایوگرافی شانزده­ کاناله ثبت گردید. داده‌های خام به حداکثر فعالیت انقباض ارادی ایزومتریک عضلات نرمال شد و RMS محاسبه گردید. تجزیه و تحلیل اطلاعات با روش آنالیز واریانس با داده­های تکراری برای ارزیابی تفاوت بین سه حالت مورد آزمایش روی یک گروه آزمودنی (05/0=p) انجام شد.
یافته­ ها
یافته ­ها، سطوح مختلفی از فعالیت عضلات را در تمرینات مختلف نشان داد؛ به‌ طوری‌ که میزان فعالیت عضله راست شکمی در تمرین پلانک و فعالیت عضله چندسر کمری حین اجرای پل و لانگ بالاترین بود.
نتیجه­ گیری
با در نظر گرفتن سطح فعالیت تمام عضلات مورد مطالعه، به نظر می‌رسد تمرین پلانک بالاترین و تمرین لانگ کمترین میزان تأثیرگذاری را در بهبود ثبات ناحیه‌ مرکزی داشته باشد.

چکیده [English]

Background and Aims: Nowadays, suspended exercises have been considered as an effective way to improve core stability in healthy individuals and those with musculoskeletal disorders. However, the activity of different core muscles while performing suspended exercises has not been investigated yet. Therefore, the purpose of the present study was to compare electromyographic activity of selected core muscles while performing selected core stability exercises using TRX.
Materials and Methods: A total of 15 healthy physically active female students participated in the current study. Each participant performed three repetitions of each of bridge, plank, and lunge exercises with the feet placed inside the TRX foot straps. Simultaneously, surface electromyographic data was collected on rectus abdominis, external oblique, erector spine lumbalis, and superficial lumbar multifidus. Resulting row data was amplitude normalized and the root mean square was then determined. Repeated-measure analysis of variance was used to determine any differences across the three exercises on a test group (p=0.05).
Results: Different levels of muscle activation were observed during the three different exercises. Rectus abdominis activation was the greatest during plank exercise, while superficial lumbar multifidus activity peaked during feet suspended lunge and bridging.
Conclusion: Considering the levels of activity of all investigated muscles, plank seems to have the highest and lunge the least impact on improving the stability of core region.
