چکیده

هدف از انجام پژوهش حاضر، مقایسة اثر سه روش تمرینی اگزرگیم و راه‌رفتن روی تردمیل بر کارکرد جسمانی (تعادل و قدرت عضلانی پاها) مرتبط با سقوط در سالمندان بود. شرکت‌کنندگان 60 نفر از سالمندان 60 تا 70 سالة شهر شیراز بودند که سابقة زمین‌خوردن و بازی اگزرگیم نداشتند و به‌صورت تصادفی انتخاب شدند. شرکت‌کنندگان فرم رضایت‌نامة مبنی‌بر شرکت در پژوهش را براساس استانداردهای پژوهشی پژوهشکدة تربیت‌بدنی و علوم ورزشی وزارت علوم تکمیل کردند. پس از انجام پیش‌آزمون، شرکت‌کنندگان به چهار گروه همسان تقسیم شدند: گروه اگزرگیم انفرادی، گروه اگزرگیم گروهی، گروه اگزرگیم شناختی و گروه تردمیل. مدت دوره چهار هفته و هر هفته سه جلسة تمرینی مجزا بود. از آزمون‌تحلیل کوواریانس چندمتغیره (مانکوا) برای تحلیل داده‌ها استفاده شد و سطح معنا‌داری آلفای 05/0 درنظر گرفته شد. ننایج نشان داد که شرکت‌کنندگان هر چهار گروه در آزمون‌های تعادل فولرتون و برخاستن و نشستن پیشرفت داشتند (0.05> P)؛ اگرچه گروه اگزرگیم شناختی در قدرت عضلانی پاها تفاوت معناداری را نشان ندادند (0.05 < P). مقایسة بین گروه‌ها نشان داد که تفاوت معناداری در تعادل فولرتون وجود نداشت؛ اگرچه گروه تمرین‌های گروهی امتیازهای بیشتری را کسب کردند. در آزمون برخاستن و نشستنن نیز تفاوت معناداری مشاهده نشد و گروه اگزرگیم انفرادی امتیازهای بیشتری را کسب کردند. براساس نتایج پژوهش، افراد غیرفعال سالمند می‌توانند به‌منظور بهبود تعادل و پیشگیری از خطر سقوط از تمرین‌های گام‌برداری اگزرگیم سود ببرند.

چکیده [English]

The aim of the current study is to compare three exergame training and treadmill walking methods on physical functions associated with fall in older adults. Sixty older adults (aged 6070) from Shiraz participated in this study. We included only those individuals who reported never having played video games and/or never had a history of falling. They gave their informed consent according to the principles outlined by the Ethics Committee of Faculty of Sport Sciences and Physical Education. The participants were not compensated for their participation. They were assigned into four homogeneous groups (single exergame (N=15), multiplayer exergame (N=15), cognitive exergame (N=15) and treadmill walking (N=1.5). After the pretest, they participated in the study for 12 sessions (4weeks, 3 sessions per week). After the last session, the post test was taken. Multivariate analysis of covariance (MANCOVA) were used to analyze the data. Results showed the participants’ balance and lower limb strength improved after these 12 sessions )P<0.05). A significant difference was not found in balance between groups in post tests )P< 0.05). The multiplayer exergame group gained better scores in balance. Also, in lower limb strength, this difference wasn’t significant. The single exergame group did better in the chair stand test. The findings indicate that sedentary older adults can benefit from stepping exergame trainings in order to reduce fall risk.
