چکیده

مقدمه و اهداف
افزایش سن، موجب کاهش عملکرد فیزیولوژیکی بدن می­شود و راه رفتن افراد را با اختلال مواجه می­سازد. از طرف دیگر بنا بر برخی مطالعات، فعالیت جسمانی منظم باعث به تاخیر انداختن این اختلالات می­شود. از این­رو هدف تحقیق حاضر بررسی تاثیر تمرینات پیلاتس بر برخی پارامترهای کینماتیک اندام تحتانی زنان میانسال سالم و کم تحرک در حین راه رفتن بود.
مواد و روش­ها
20 زن میانسال سالم و کم تحرک با دامنه سنی 50-45 سال برای شرکت در تحقیق حاضر به صورت هدفمند انتخاب شدند. در پیش­آزمون، بعد از قرارگیری آزمودنی روی تردمیل، به مدت یک دقیقه به گام­برداری پرداخت، سپس گام­های برداشته شده در 30 ثانیه انتهایی آزمودنی­ها به وسیله سیستم سه بعدی آنالیز حرکت با 6 دوربین و با سرعت 120 هرتز ثبت شد. سپس آزمودنی­ها به مدت هشت هفته برنامه تمرینی پیلاتس را انجام دادند و پس از آن پس­آزمون مشابه با پیش آزمون اجرا شد. پردازش داده­ها با نرم­افزار کورتکس صورت گرفت و سپس پارامترهای مورد نظر شامل دامنه حرکتی مفاصل ران، زانو و مچ پا در مرحله سوینگ و استانس، زوایای مفاصل ران زانو و مچ پا در لحظه برخورد پاشنه با زمین و جدا شدن پنجه و نیز پارامتر طول گام استخراج شد. تجزیه و تحلیل آماری داده­ها به وسیله نرم­افزار SPSS22 و با استفاده از آزمون تی­همبسته در سطح معناداری 05/0 انجام گرفت.
یافته­ها
نتایج آزمون تی همبسته نشان داد تفاوت معناداری در پارامترهای بررسی شده وجود ندارد.
نتیجه­ گیری
با توجه به نتایج تحقیق حاضر، هشت هفته تمرینات منتخب پیلاتس بر کینماتیک اندام تحتانی در حین راه رفتن زنان میانسال سالم و کم‌تحرک تاثیرگذار نبود. عدم تاثیرگذاری تمرینات احتمالا به دلیل این است که افراد میانسال نسبت به افراد سالمند کمتر تحت تاثیر عوارض فیزیولوژیکی افزایش سن قرار دارند و عملکرد راه رفتن آن­ها هنوز با اختلال مواجه نشده است.

چکیده [English]

Background and Aim: Aging reduces the physiological function of the body and perturbs the gait. On the other hand, based on the previous studies, regular physical activities postpone these perturbations. The purpose of the present study was to investigate the effects of Pilate's exercises on some lower extremity kinematics parameters in healthy sedentary middle age women during walking.
Materials and Methods: A total of 20 healthy middle-aged sedentary women, between 50-45 years old, were purposefully selected to participate in the present study. In pre-test, each participant placed on a treadmill, then she walked on the treadmill for one minute. Then, the final 30-second of walking was recorded using the two-dimensional motion analysis system with 6 cameras at 120 Hz speed rate. Then, participants performed eight weeks of Pilates which was followed by a post-test similar to the pre-test. The Cortex software was used for data processing. Statistical analyses of data was performed using SPSS, version 22, running a paired T-test at a significant level of 0.05. Then, The desired parameter, including the hip, knee, and ankle motion range during the swing and stance phases were measured. Moreover, hip, knee, and ankle joint angles at both the heel contact and toe off moments were evaluated. Finally, the length step parameter was extracted, as well.
Result: The results showed no significant differences between the evaluated parameters.
Conclusion: The present study showed that the eight weeks of Pilates training does not affect the lower extremity kinematics during walking in healthy sedentary middle-aged women. This must be due the fact that the aging physiological problems in middle aged women are less than those in the elderly.
