بسکتبال امروزی

   نوشته شده توسط: محسن عسگری    

امروزه با این که ورزش بسکتبال یکی از معروفترین و پرطرفدارترین ورزش‌های جهان است و تغییرات زیادی یافته‌است، هنوز اصول اساسی آن مانند زمان دکتر ناسمیت است.(سبد هلو)

 

زمین بسکتبال

یک زمین قانونی و مناسب برای بسکتبال باید کاملاً مسطح و بدون هر گونه مانع و بر آمدگی باشد. این ورزش را نمی‌توان در زمین‌های خاکی یا چمن اجرا کرد. بلکه سطح زمین باید از مواد سفت مانند آسفالت، سیمان یا چوب پوشیده شده باشد. میدان‌های بسکتبال همه به یک اندازه نیست. زمین بازی برای خردسالان کوچکتر از زمین بزرگسالان است. مسابقات رسمی در میدان‌هایی به شکل مستطیل به طول ۲۶ متر و عرض ۱۴ متر برگزار می‌شود که طول وعرض زمین را می‌توان به نسبت دو متر در یک متر کم و زیاد کرد. زمین بسکتبال به شکل خاصی خط کشی می‌شود. خط‌های دور زمین به پهنای ۵ سانیی متر است. از مرکز زمین و به موازات عرض زمین خطی کشیده می‌شود که زمین بازی را به دو قسمت مساوی تقسیم می‌کند. در وسط زمین دو دایره متحدالمرکز رسم می‌کنند به شعاع‌های ۹۰ سانتی متر و ۱٫۸۰ متر. مرکز این دایره‌ها که درست مرکز زمین است محل آغاز بازی است .
