چکیده
زمینه وهدف: هدف تحقیق مقایسه تراکم و محتوای مواد معدنی استخوان اندام برتر و غیر برتر مردان نخبه کاراته کار استان خراسان جنوبی بود. روش تحقیق:آزمودنی های این پژوهش تعداد 27 مرد کاراته کا (میانگین سنی: 23 / 2 ± 6/ 23 سال) بودند. کاراته کاها از بین افرادی که حداقل 5 سال سابقه ورزشی مستمر یا عضویت در تیم ملی را داشتند و از سلامت بدنی و رژیم غذایی طبیعی برخوردار بودند، انتخاب شدند. با استفاده از روش DEXA ، میزان تراکم و محتوای مواد معدنی استخوان ران (نواحی گردن، برجستگی بزرگ و انتهای نزدیک به تنه) و ساعد (انتهای دور از تنه استخوان زند زیرین و زند زبرین و استخوان های مچ دست) شرکت کنندگان اندازه گیری شد. جهت تجزیه و تحلیل داده ها از آزمون t مستقل در سطح معناداریp≤0/05 بهره گرفته شد. یافته ها: نتایج نشان داد که میزان تراکم و محتوای استخوان ناحیه ساعد دست برتر از دست غیر برتر کاراته کاها به طور معنی دار (به ترتیب P=0/001و p=0/05) بالاتر است. همچنین تراکم مواد معدنی استخوان ران پای غیر برتر کاراته کاها در مقایسه با پای برتر، به طور معناداری (p=0/03) بالاتر بود. نتیجه گیری: نتایج تحقیق حاضر حاکی از آن است که ورزش کاراته به طور موثر موجب بهبود وضعیت استخوانی ورزشکاران می شود؛ اما در مقایسه وضعیت استخوانی دو سمت بدن، به نظر می رسد ناحیه ساعد دست برتر و ران پای غیر برتر کاراته کاها به علت فشارهای مکانیکی وارد شده و استفاده بیشتر و کارآمدتر اندام یک طرف، وضعیت استخوانی بهتری دارد.

چکیده [English]
Background and Aim: The purpose of this study was to comparison of the bone mineral density and content between dominant & nondominant limb in elite males Karate practitioners of southern Khorasan. Materials and Methods: Participants were 27 Karate practitioners (age 23.6±2.23 yr.) with minimally 5 years experience in karate sport, play in the national team level, healthy state, and normal diet. The bone mineral density and content in thigh bone (neck, trochanteric and proximal) and forearm area (two third of distal of ulna & radius, and carpal bones) measured By DEXA method. It is applied the independent-samples T test for extraction of results and significant differences where p≤0.05. Results: Result showed that bone mineral density and content of the forearm area in dominant hand was significantly higher (p=0.001 & p=0.05 respectively) than nondaminant hand of Karate practitioners. In addition, the thigh bone mineral density of nondominant leg in karate practitioners was significantly higher (p=0.03) than dominant leg. Conclusion: Present results suggest that Karate sport can efficiently improve bone condition; but in comparison of two sides of body, it seem that forearm area of dominant hand and thigh area of nondominant leg of Karate practitioners have a better bone mineral density or content than to opposite sides due to more mechanical stresses and more utilization of one side of the body.
