چکیده

مقدمه و اهداف
هدف از پژوهش حاضر، بررسی قدرت، استقامت و انعطاف­پذیری عضلات تنه در نوجوانان کشتی­گیر با و بدون ناهنجاری هایپرکایفوز بود.
مواد و روش­ها
در تحقیق حاضر 40 کشتی­ گیر به ­صورت هدفدار انتخاب شدند و به دو گروه با و بدون ناهنجاری هایپرکایفوزیس تقسیم شدند. میزان هایپرکایفوز، استقامت عضلات اکستنسور و فلکسور تنه به ­ترتیب به­ وسیله خط ­کش منعطف، آزمون سورنسن و آزمون فلکشن 60 درجه مورد اندازه­ گیری قرار گرفتند. قدرت عضلات اکستانسور و فلکسور با دینامومتر و انعطاف ­پذیری عضلات توراکو-ابدومینال با آزمون عملکردی اندازه­ گیری شد. آنالیز داده ­ها با آزمون همبستگی پیرسون و آزمون تی مستقل انجام شد.
یافته­ ها
بین هایپرکایفوز و قدرت اکستنشن تنه (0/005=p)، استقامت عضلات اکستانسور تنه (0/02=p) و همچنین انعطاف­ پذیری سینه­ ای-شکمی (0/01=p)، نسبت قدرت عضلات فلکسور به اکستنسور تنه (0/001=p) و همچنین نسبت استقامت عضلات فلکسور به اکستنسور تنه (0/001=p) ارتباط معناداری وجود داشت. علاوه بر این، مقایسه دو گروه نشان داد که بین قدرت عضلات اکستنسور تنه (0/02=p)، نسبت قدرت عضلات فلکسور به اکستنسور (0/001=p)، استقامت عضلات اکستنسور تنه (0/009=p)، نسبت استقامت عضلات فلکسور به اکستنسور تنه (0/005=p) و نیز انعطاف­پذیری عضلات توراکو-ابدومینال (0/02=p) تفاوت معناداری در دو گروه وجود دارد.
نتیجه­ گیری
نتایج تحقیق حاضر نشان داد که تغییرات در فاکتورهایی همچون قدرت، استقامت و انعطاف ­پذیری می­تواند موجب تشدید قوس ستون فقرات پشتی شود و این عوامل در افراد ورزشکار مثل کشتی­ گیران نیز علی­رغم ورزشکار بودن افراد می­تواند به­ عنوان یک ناهنجاری تلقی شود؛ لذا مربیان و درمانگران ورزشی می­ بایست نسبت به ارزیابی و ارائه برنامه تمرینات موثر آموزش داده شوند.

چکیده [English]

Background and Aims: The purpose of the present study was to investigate the strength, endurance, and muscles flexibility in Teenage wrestlers with and without hyper kyphosis.
Materials and Methods: In the current study, 40 wrestlers were purposefully selected and divided into two groups of with and without hyper kyphosis. Hyper kyphosis and endurance of extensor and flexor muscles of trunk were measured using flexible ruler, Sorensen test, and test of trunk flexion at 60 degree, respectively. The strength of extensor and flexor muscles were evaluated using a digital dynamometer and thoracoabdominal Flexibility was measured using functional test. To analyze the data, Pearson correlation test and independent T test were used.
Results: There were significant relationships among hyper kyphosis and strength of trunk extension (p=0.005), endurance of trunk extensor muscles (p=0.02), thoracoabdominal Flexibility (p=0.01), the ratio of trunk flexor to trunk extensor muscles strength (p=0.001), and the ratio of trunk flexor to trunk extensor muscles endurance (p=0.001). In addition, there were significant differences between the two groups in trunk extensor muscles strength (p=0.02), the ratio of trunk flexor to trunk extensor muscles strength (p=0.001), endurance of trunk extensor muscle (p=0.009), the ratio of trunk flexor to trunk extensor muscles endurance (p=0.005), and thoracoabdominal Flexibility (p=0.02).
Conclusion: The results showed that the changes in factors such as strength, endurance, and flexibility can aggravate the dorsal arch of spine and these factors in athletes, such as wrestlers, can be considered as abnormal despite being athletes. Therefore, coaches and athletic trainers should be trained to evaluate these factors and provide an effective training program.
