چکیده

مقدمه و اهداف
در ورزشکاران، برخورداری از تعادل پویای بهینه در جهت بهبود عملکرد حرکتی و یا پبشگیری از آسیب حین تمرین حائز اهمیت است؛ لذا هدف از مطالعه حاضر بررسی اثر تمرین اصلاحی راستای اندام تحتانی همراه با فعال­سازی ارادی عضلات گلوتئال بر تعادل پویا حین دویدن بر روی تردمیل بوده است.
مواد و روش­ ها
در مطالعه شبه­ تجربی حاضر 25 آزمودنی زن سالم و فعال در دو گروه کنترل (12 نفر، میانگین سنی 2/8±21/2) و گروه تمرینی (13 نفر، میانگین سنی 2/5±20/5) با روش نمونه­گیری در دسترس شرکت کردند. تمرینات اصلاحی در 8 جلسه به مدت  دو هفته در گروه تمرینی انجام شد و در دو گروه قبل و بعد از دو هفته تعادل پویای افراد توسط تست ستاره در سه جهت قدامی، خلفی-داخلی و خلفی-خارجی انجام شد. تحلیل آماری توسط آزمون آماری تی مستقل جهت مقایسات بین گروهی و تی زوجی جهت مقایسات درون­گروهی با سطح معناداری 0/05 انجام شد.
یافته­ ها
نتایج نشان داد که در پیش­ آزمون دو گروه تفاوت معناداری از نظر شاخص ­های تعادلی در جهات مختلف نداشتند (0/05˃p) و مقایسات درون­گروهی در گروه تمرینی حاکی از تفاوت معنادار و افزایش میزان دست­یابی در جهت قدامی (0/008=p) و خلفی-خارجی (0/011=p) بود، در حالی که در جهت خلفی-داخلی (0/727=p) تفاوت معناداری مشاهده نشد و در گروه کنترل نیز تفاوت معناداری مشاهده نگردید (0/05˃p).
نتیجه­ گیری
نتیجه مطالعه حاضر نشان داد که این تمرینات اصلاحی احتمالا از طریق تاثیر بر عملکرد عضلات گلوتئال توانسته است تعادل پویای تست ستاره را در جهت قدامی و خلفی-خارجی در زنان سالم و فعال تا حدودی بهبود دهد که این امر از نظر رویکردهای پیشگیری از آسیب می­تواند حائز اهمیت باشد و در برنامه­ های آماده­ سازی مورد استفاده قرار گیرد.

چکیده [English]

Background and Aims: Possessing ideal dynamic balance in athletes is of crucial importance in order to improve the movement and to prevent injuries during exercises; therefore, the aim of the present  study was to assess the effect of lower limb corrective exercise along with gluteal muscle activation in  dynamic balance while treadmill running.
Materials and Methods: In the present quasi experimental design study, a total of 25 healthy active women with convenient sampling method participated in two groups of control (12 cases with average age of 21.2±2.8) and experimental (13 cases with average age of 20.5±2.5). In the experimental group, corrective exercise was performed in eight sessions during two weeks and pre and post balance test were administered for the two groups using Star Excursion Balance Test (SEBT) in three anterior, posteromedial, and posterolateral directions. Statistical analyses were performed using pair t test for within group comparison and independent t test for between group comparisons with the significance level set at 0.05.
Results: The results showed that the two groups had no significant differences in balance indicator for different directions on pretest (P˃0.05) and within group comparisons in experimental group illustrated significant differences in anterior (P =0.008) and posterolateral directions (P = 0.011), while in posteromedial direction no significant differences were found (P˃0.05).
Conclusion: The results of the presented study demonstrated that this corrective exercise has probably been able to improve dynamic balance in anterior and posterolateral directions of SEBT in healthy active women possibly through having impact on gluteal muscles function, thus to this could be considerable in terms of injury preventing approaches and can be used in conditioning programs.
