چکیده

پژوهش حاضر به بررسی تأثیر دستکاری سیستم‌های دخیل بر کنترل پاسچر شناگران با سابقه و مبتدی می‌پردازد. مطالعه بر روی 80 نفر از شناگران (دختر و پسر) با دامنۀ سنی 15 تا 20 سال انجام گرفت که به روش نمونه‌گیری غیرتصادفی هدفدار برای پژوهش انتخاب شده بودند. در این مطالعه برای اندازه‌گیری کنترل پاسچر از آزمون عملکردی ایستادۀ تک‌اندام (SLS) تحت چهار شرایط حسی مختلف (ایستادن روی سطح سخت با چشمان باز، ایستادن روی فوم با هایپراکستنشن سر، ایستادن روی سطح سخت با چشمان بسته و هایپراکستنشن سر، و ایستادن روی فوم با چشمان بسته) استفاده شد. تجزیه‌وتحلیل داده‌ها با استفاده از آزمون تحلیل واریانس یکطرفه، برای بررسی تغییرات بین‌گروهی؛ و آزمون تعقیبی توکی برای مقایسه‌های دوبه‌دو در سطح معناداری (05/0P≤) استفاده شد. نتایج نشان داد؛ سهم سیستم دهلیزی در کنترل پاسچر شناگران باسابقه نسبت به شناگران مبتدی بیشتر است (03/0P=). همچنین تفاوتی در سیستم‌های بینایی و حس عمقی در شناگران باسابقه نسبت به شناگران مبتدی مشاهده نشد. از این ‌رو می‌توان نتیجه گرفت که شنا موجب تقویت سیستم دهلیزی می‌شود.

چکیده [English]

The present study examined the effect of manipulating systems involved in postural control of professional and beginner swimmers. The study was conducted on 80 swimmers (male and female, age range: 15 - 20 years old) who were selected by non-random purposive sampling method. In this study, single leg stand test (SLS) was used to measure postural control under four different sensory conditions: 1) Standing on the hard surface with open eyes, 2) Standing on a foam with hyperextension of the head, 3) Standing on the hard surface with closed eyes and hyperextension of the head, 4) standing on a foam with closed eyes. For data analysis, one-way ANOVA was used to examine the intergroup changes and Tukey post hoc test was used for paired comparisons at a significance level (P≤0.05). The results showed that the share of vestibular system in the control postural of professional swimmers was higher than that of beginner swimmers (P=0.03). Also, there was no difference in visual and proprioceptive systems between professional and beginner swimmers. So it can be concluded that swimming improves the vestibular system.
