چکیده

هدف از پژوهش حاضر، بررسی اثر هشت هفته تمرینات تی آر ایکس، حس عمقی و ترکیبی بر میزان قدرت و دامنۀ حرکتی مفصل شانه در زنان ورزشکار با سابقة دررفتگی شانه بود. جامعۀ آماری پژوهش را ورزشکاران زن شرکت‌کننده در باشگاه‌های ورزشی شهرستان خرم‌آباد با سابقۀ دررفتگی شانه بدون انجام عمل جراحی در بهار سال 1399 تشکیل می‌داد. نمونۀ آماری پژوهش شامل 32 ورزشکار زن داوطلب بود که با توجه به معیارهای ورود انتخاب و به‌طور تصادفی در چهار گروه هشت نفری تی آر ایکس، تمرین حس عمقی، تمرین ترکیبی و کنترل قرار گرفتند. قدرت ایزومتریک و دامنة حرکتی چرخش داخلی و خارجی مفصل شانه به ترتیب با روش استاندارد کندال و صاحب‌الزمانی و همکاران اندازه‌گیری شد. پروتکل تمرین گروه‌های تجربی شامل تمرینات تی آر ایکس، حس عمقی و ترکیبی به‌صورت هفته‌ای سه جلسه، به مدت هشت هفته اجرا شد. قبل از شروع مطالعه و پس از هشت هفته اجرای پروتکل‌های تمرینی، متغیرهای پژوهش اندازه‌گیری شدند. نتایج نشان داد اجرای هشت هفته تمرینات تی آر ایکس، حس عمقی و ترکیبی به افزایش معنا‌دار میانگین قدرت و دامنۀ حرکتی مفصل شانه منجر می‌شود. همچنین، در پس‌آزمون، میانگین قدرت و دامنۀ حرکتی مفصل شانه در گروه ترکیبی، در مقایسه با گروه‌های تمرینات تی آر ایکس و حس عمقی افزایش معنا‌داری داشت، اما مقایسۀ میانگین قدرت و دامنۀ حرکتی مفصل شانه بین دو گروه تمرینات تی آر ایکس و حس عمقی تفاوت معنا‌داری را نشان نداد. به نظر می‌رسد برنامۀ تمرین ترکیبی با کسب ویژگی هر دو روش تمرینی تی آر ایکس و حس عمقی می‌تواند روشی مفید برای بهبود قدرت و دامنۀ حرکتی مفصل شانه در ورزشکاران دچار دررفتگی شانه باشد.

چکیده [English]

This study aimed to evaluate the effect of 8 weeks of TRX, proprioceptive and combined training on strength and range of motion of the shoulder joint in female athletes with a history of shoulder dislocation injury. 32 subjects with a history of shoulder dislocation without surgery were selected voluntarily and randomly divided into 4 groups of TRX training, proprioceptive training, combined training, and control. Isometric strength and range of motion of internal and external rotation of the shoulder joint of subjects were measured before and after 8 weeks. Experimental groups had 3 training sessions per week for 8 weeks. Trainings included selected TRX training, proprioceptive trainings and combination of these two. Data analysis was performed using a dependent t-test, one-way analysis of variance and Tukey test (P≥0.05). The results showed that 8 weeks of TRX, proprioceptive and combined trainings led to a significant increase in strength and range of motion of the shoulder joint. Also, the mean strength and range of motion of the shoulder joint in the combined training group showed a significant increase compared to the TRX and proprioceptive training groups, but there was no significant difference between the two groups of TRX and proprioceptive. Combined training program with the features of both TRX and proprioceptive training protocols can be a useful method to improve the strength and range of motion of the shoulder joint after shoulder dislocation injury.
