چکیده

اهداف: ثبات مرکزی و تقویت عضلات ثبات‌دهنده مرکزی به یکی از بحث‌های جدید دنیای پزشکی ورزشی تبدیل شده است. هدف اصلی پژوهش حاضر مقایسه تأثیر هشت هفته تمرینات TRX و CX WORX بر قدرت و استقامت عضلات بخش مرکزی و تعادل پویای دانشجویان دختر بود.
مواد و روش‌ها: مطالعه حاضر از نوع نیمه‌تجربی است. سی دختر دانشجوی جوان که همگی از سلامت عمومی برخوردار بودند، به ‌طور داوطلبانه در این تحقیق شرکت کردند که به‌ صورت تصادفی به سه گروه تجربی تمرینات TRX ده نفر، تمرینات CX WORX ده نفر و گروه کنترل نیز ده نفر تقسیم شدند. از آزمودنی‌ها قبل از شروع تمرینات، قدرت عضلات تنه با آزمون دراز و نشست، آزمون تعادل پویا توسط تست Y و استقامت ناحیه مرکزی با استفاده از آزمون‌های استقامت عضلات تنه مک‌گیل به ‌عنوان پیش‌آزمون به عمل آمد. سپس گروه‌های تجربی به انجام تمرینات منتخب هشت هفته‌ای (سه جلسه در هفته) پرداختند. در طی این مدت از گروه کنترل خواسته شد که فعالیت‌های روزانه خود را حفظ کنند. پس از اتمام تمرینات از سه گروه، پس‌آزمون به عمل آمد. برای بررسی نرمال بودن داده‌ها از آزمون شاپیرو ویلک و برای مقایسه داده‌ها از آزمون آنالیز واریانس با اندازه‌های مکرر در سطح معناداری 05/P≤0 استفاده شد.
یافته‌ها: نتایج تحقیق حاضر نشان‌دهنده تأثیر مثبت هر دو تمرین TRX و CX WORX بر قدرت، استقامت و تعادل پویا آزمودنی‌ها بود، به ‌گونه‌ای که میانگین نمرات متغیرها پس از تمرینات نسبت به گروه کنترل و پیش‌آزمون افزایش داشت. همچنین در مقایسه دو گروه آزمایشی به ‌غیر از جهت قدامی تعادل Y در سایر متغیرهای آزمودنی‌های گروه TRX عملکرد بهتری نسبت به گروه آزمایشی CX WORX از خود نشان دادند (05/P≤0).
نتیجه‌گیری: به ‌طور کلی، نتایج پژوهش حاضر نشان‌دهنده تأثیر هر دو بر متغیرهای قدرت، استقامت و تعادل پویا بود، اما تأثیر تمرینات TRX بیشتر بود؛ بنابراین به کاردرمان‌ها و مربیان پیشنهاد می‌شود از هر دو، به‌خصوص تمرینات TRX جهت بهبود قدرت و استقامت عضلات بخش مرکزی استفاده کنند.

چکیده [English]

Background and Aims: Core stability and strengthening core stability muscles have become one of the new topics in the field of sports medicine. The present study aims to compare the effects of eight weeks of TRX and CXWORX exercises on core endurance, trunk muscle strength, and dynamic balance of female college students.
Methods: This quasi-experiment study was conducted on 30 young healthy female college students. They were randomly divided into two experimental groups of TRX (n=10), CXWORX (n=10) and one control group (n=10). In the pre-test phase, trunk muscle strength was evaluated by sit-up test, dynamic balance by Y-balance test, and core endurance by McGill core endurance test. Then, experimental groups performed eight weeks of selected training program, 3 sessions per week, while the control group was asked to do their daily activities. After intervention, the three groups underwent post-test assessments. Shapiro-Wilk test was used to investigate the normality of data distribution, and repeated measured ANOVA was used to compare data. The significance level was set at P≤0.05.
Results: Both TRX and CXWORX had a positive effect on the participants’ trunk muscle strength, core endurance, and dynamic balance such that their mean scores increased after training. The TRX group performed better than the CXWORX group in all study variables (P≤0.05), except for the Y balance at the anterior direction.
Conclusion: Both TRX and CXWORX exercises have positive effects on the trunk muscle strength, core endurance, and dynamic balance of female college students, where the effect of TRX was greater. Therefore, occupational therapists and trainers are recommended to use both exercises, especially TRX to improve core muscle strength and endurance.
