چکیده
پژوهش حاضر با هدف بررسی اثر شش هفته تمرین با زمان‌بندی حسی بیرونی بر میانگین سرعت و دامنة مرکز فشار تعادل ایستا و پویای سالمندان انجام شد.در این مطالعه 36 مرد سالمند به‌طور تصادفی به سه گروه کنترل، راه‌رفتن ساده و گروه تمرین با زمان‌بندی حسی بیرونی تقسیم شدند. تمرین‌ها به‌مدت شش هفتة سه‌جلسه‌ای انجام شد. آزمودنی‌ها قبل و بعد از تمرین‌ها در آزمون‌های تعادلی ایستا و پویا شرکت کردند. نتایج تفاوت معنا‌داری را بین گروه‌ها در پیش‌آزمون و پس‌آزمون متغیرهای سطح و مسافت مرکز فشار نشان نداد؛ بااین‌حال، تمرین با زمان‌بندی حسی بیرونی موجب افزایش معنا‌دار دامنة مرکز فشار در مسیر قدامی-خلفی و داخلی-خارجی در گروه تجربی شد. نتایج نشان داد استفاده از این تمرین‌ها می‌تواند موجب بهبود معنا‌دار تعادل پویای سالمندان شود؛ بنابراین، می‌توان این روش تمرینی را به‌عنوان روشی کم‌هزینه، نوین و ساده در برنامه‌های تمرینی مربوط به بهبود تعادل پویای سالمندان جای داد.

چکیده [English]
The purpose of this study was to investigate the effect of training with external sensory timing on the mean area and amplitude of the center of pressure during static and dynamic balance in the elderly. Thirty-six elderly (all males) were randomly assigned to control, walking, and training with external sensory timing (experimental) groups.
The training sessions were conducted during six weeks (three sessions per week). The participants were administered two postural tasks of static and dynamic balance prior and following the treatments as their pre- and post-tests. The results indicated that there were no significant differences in the center of pressure area and distance means from pre- to post-tests of all groups. However, training with external sensory timing significantly increased the amplitude of the center of pressure in the anterior-posterior and the internal-external directions of the experimental groups. The results indicated that training with external sensory timing significantly improved the dynamic balance of the elderly. Therefore, this method can be considered as a low-cost, modern, and simple method to be included in the training programs of the elderly to improve their dynamic balance.
