چکیده
با توجه به این احتمال که فعالیت­های ورزشی تغییراتی در توزیع پارامترهای مختلف فشار کف پایی در حین گام­برداری به وجود می­آورند، هدف مطالعۀ حاضر مقایسۀ الگوی توزیع فشار کف پایی بین پای راست و چپ و ارتباط آنها با پارامترهای آنتروپومتریک است. بدین­منظور، 10 کشتی­گیر نخبه با میانگین و انحراف استاندارد سنی 3/33±23/6 سال، قد 7/67±173/5 سانتی­متر و جرم: 21/8±83/3 کیلوگرم در این مطالعه بصورت داوطلبانه مشارکت کردند. از دستگاه EMED-AT2 برای تحلیل فشار کف پایی، از آمار پارامتریک روش تی زوجی جهت مقایسۀ پارامترها بین پای راست و چپ و از روش پیرسون برای تعیین همبستگـی بین متغیرهـا استفاده شد. تنهـا در پارامتر سطح تمـاس در ناحیـۀ 4 بین پـای راست و چپ اختلاف معنـادار یافت شـد (0/05≥p، 0/03=ES). بین تمامی پارامترها با قد و جرم همبستگی مثبت و معنادار یافت شد0/01 p≥0/05، p≥) و تنها در نواحی پاشنه همبستگی بین حداکثر نیرو در پای راست با قد (پاشنه داخلی 0/45=r2، پاشنۀ خارجی 0/68=r2) و جرم (پاشنۀ داخلی 56 /0=r2، پاشنۀ خارجی 0/8=r2) و در پای چپ با قد (پاشنۀ خارجـی 0/53=r2) و جرم (پاشنۀ خارجـی 0/55=r2) معکوس شد (0/05≥p). با توجه به فقدان اختلاف معنادار در پارامترهـای مختلف فشار کف پایـی بین پای راست و چپ می­توان ادعا کرد، در ورزش کشتی تقاضای عملکردی پاها یکسان است. همچنین، این پژوهش نتایج تحقیقات گذشته را مبنی بر فقدان پای غالب در رشتۀ کشتی تأیید کرد.

چکیده English

Since, sports activities are likely to be changes in various parameters of plantar pressure distribution during walking to create, This study compared patterns of plantar pressure distribution between right and left feet and their relationship with anthropometric parameters. 10 elite wrestler with the average and standard deviation of age: 23.6±3.33 yrs, height: 173.5±7.67 cm and mass: 83.3±21.8 kg voluntarily participated as subjects in this study. EMED-AT2 System for plantar pressure analysis, of parametric statistical methods paired t-test to compare parameters between the right and left leg and also of the Pearson methods for investigating correlation between variables was used. The only in the contact area parameter between the right leg and left at 4th mask significant differences were found (p≤0.05, ES=0.03). Also positive and significant correlation between height and mass with all the parameters were found (p≤0.01, p≤0.05) and in the heel area the correlation between maximum force in the right foot with height (medial heel r2=0.45 ; lateral heel r2=0.68) and weight (medial heel r2=0.56 ; lateral heel r2=0.8) and in the left foot with height (lateral heel r2=0.53) and weight (lateral heel r2=0.55) was reversed. (p≤0.05). Considering the lack of significant differences in plantar pressure parameters between the right and left foot, it could be argued, in wrestling foot demand function is the same. Also this research confirmed the results previous study indicating the absence of dominant leg in wrestling.
