درباره نویسنده
پرتاب وزنه از شاخههای ورزش پایه دو و میدانی است. پرتاب کننده در وسط دایرهای به قطر ۲۱۳ سانتی متر قرار میگیرد که به وسیله باند آهنی یا چوبی محصور شدهاست، یک گوی آهنی به وزن ۷/۲۵۷ گرم برای مردان و نصف همین وزن برای زنان را با یک دست در بالای شانه میگیرد و بیآنکه پا را از دایره پرتاب بیرون بگذارد، وزنه را با تمام قدرت پرتاب میکند.
