بررسی نقش شدت و حجم فعالیت بدنی در طول عمر بر بهبود عملکرد ورزشی و آمادگی جسمانی معلمان تربیت بدنی
کلمات کلیدی:
آمادگی جسمانی, ترکیب بدن, فعالیت بدنی در طول عمر, فعالیت بدنی شدید, عملکرد ورزشی, معلمان تربیت بدنیچکیده
فعالیت بدنی مستمر در طول عمر نقش موثر و کلیدی بر سلامت و عملکرد جسمانی دارد؛ نقشی که برای معلمان تربیت بدنی، بهعنوان الگوهای رفتاری و کنشگران اصلی آموزش سبک زندگی فعال، اهمیت دوچندان مییابد. بااینحال، پژوهشهای محدودی به بررسی تأثیر شدت و میزان فعالیت بدنی بر عملکرد ورزشی و آمادگی جسمانی این گروه شغلی پرداختهاند. هدف مطالعه حاضر، بررسی نقش شدت و میزان فعالیت بدنی در طول عمر و فعالیت بدنی کنونی بر عملکرد ورزشی و آمادگی جسمانی معلمان تربیت بدنی مرد استان خوزستان بود. مطالعه حاضر بهصورت مقطعی انجام شد. 105 معلم مرد (میانگین سنی: 7/38±12/76سال) به روش نمونهگیری خوشهای چندمرحلهای انتخاب شدند. فعالیت بدنی در طول عمر و فعالیت بدنی کنونی بترتیب با استفاده از پرسشنامههای HLAQ و IPAQ، ترکیب بدن از طریق شاخص توده بدن، و عملکرد ورزشی و آمادگی جسمانی از طریق آزمونهای مهارتی، ایستگاهی و هوازی ارزیابی شد. فعالیت بدنی شدید در طول عمر با مهارت ورزشی (46/0=r)، عملکرد ایستگاهی (60/0=r) و عملکرد کلی (55/0=r) همبستگی قویتری نسبت به فعالیت متوسط یا کنونی نشان داد (05/0 >p). معلمان با وزن نرمال و سن کمتر عملکرد بهتری داشتند. فعالیت بدنی شدید، سن و شاخص توده بدنی بهترتیب 51%، 28% و 53% عملکرد کلی، مهارتی و ایستگاهی را پیشبینی کردند. فعالیت بدنی شدید و مستمر در طول عمر، همراه با ترکیب بدنی بهینه، نقش کلیدی در بهبود عملکرد ورزشی و آمادگی جسمانی معلمان تربیت بدنی دارد. برنامههای مداخلهای هدفمند برای تشویق فعالیتهای شدید و مدیریت وزن توصیه میشود.
