چکیده

مقدمه و هدف
انعطاف پذیری جزء مهمی از عملکرد طبیعی سیستم عضلانی  اسکلتی می باشد. به همین منظور تمرینات انعطاف پذیری، جزء ثابت برنامه های آماده سازی ورزشکاران محسوب شده و به صورت عمومی پیش از تمرین یا شرکت در رقابت های ورزشی پیشنهاد می گردد. با توجه به نتایج ضد و نقیض در فواید کاربرد استرچینگ در برنامه ی گرم کردن از یک سو و کاربرد ویبراسیون عمومی بدن (whole body vibration:WBV) برای بهبودی انعطاف پذیری از سوی دیگر، هدف از مطالعه ی حاضر بررسی اثر ویبریشن عمومی بدن بر انعطاف پذیری اندام تحتانی در زنان جوان سالم می باشد.
مواد و روش ها
 25 زن جوان سالم با میانگین سنی 09/1±76/20 سال در این مطالعه شرکت کردند. انعطاف پذیری این افراد قبل و بعد از مداخله با استفاده از آزمون های Passive Knee Extension  , Hip Flexion و Modified sit and Reach اندازه گیری شد. سپس شرکت کنندگان به حالت نیمه اسکات روی پلت فورم دستگاه WBV (فرکانس30 هرتز، آمپلی تود2 میلی متر ) در پنج ست 60 ثانیه ای و60 ثانیه استراحت بین ست ها ایستادند.
یافته ها
 پس از اعمالWBV، انعطاف پذیری همسترینگ, فلکسورهای هیپ در هر دو پا و نیز انعطاف پذیری عمومی بدن بطور معنی داری نسبت به قبل از آن افزایش یافت (00/0=P) .نتایج نشان دادند که انعطاف پذیری همسترینگ و فلکسورهای هیپ بین دو پای راست وچپ قبل از مداخله با یکدیگر اختلاف معنی داری دارند(05/0≥P ). ولی پس از اعمال WBV بین انعطاف پذیری فلکسورهای هیپ در دو پا تفاوت معنی دار وجود نداشت (14/0=P).
نتیجه گیری
 یافته های این مطالعه نشان می دهد که کاربرد WBVمی تواند روش تمرینی مناسبی برای افزایش انعطاف پذیری اندام تحتانی باشد.

چکیده [English]

Background and Aim: Flexibility is an important component of the normal musculoskeletal system function. Therefore, flexibility exercises as a basic component of athletes’ warm–up programs are generally recommended before training or participating in sports competitions. Due to the controversy in use of stretching in the warm-up programs, as well as the use of whole body vibration (WBV) in improving flexibility, the aim of the present study was to investigate the effects of WBV on lower extremity muscles flexibility in healthy young women.
Materials and Methods: A total of 25 healthy young women with an average of age 20/76±1/09 years old participated in the present study. Their flexibility were measured using passive knee extension test, hip flexion, test and modified sit and reach test before and after the intervention. Participants stood on WBV equipment (f=30 Hz, Amp=2mm 5×60s hold +60srest) in semi squat position.
Results: After WBV, the flexibility of the hamstring and hip flexor as well as general flexibility significantly increased (P=0/000). The results showed that, before WBV, there was significant differences in hamstring and hip flexors flexibility between the two legs (P≤0/05), but after WBV, no significant difference was observed in hip flexors flexibility (P=0/14).
Conclusion: The findings of the study indicate that the WBV seems to be a suitable training method for improving lower extremity muscular flexibility.
