رمي القرص

(تم التحويل من رمي قرص)

يبدأ رمي القرص من داخل دائرة قطرها 2.5 متر، يُحظر على المتسابق أن يتعداها، والقرص مصنوع من الخشب المحاط بالحديد، ويبلغ قطره 22 سم ووزنه 2 كجم، وقد يزن كيلوجراما واحدا فقط في المباريات النسائية. ويقوم المتسابق بالدوران عدة مرات حول نفسه، لكي يكسب القرص أقصى سرعة ممكنة، وفي حركة استرخاء أخيرة للذراع، يزيد من القوة الطاردة لكي يقوم برمي القرص أخيرا.

التاريخ

 
Modern copy of the Diskophoros, attributed to Alkamenes

The sport of throwing the discus traces back to it being an event in the original Olympic Games of Ancient Greece.[1] The discus as a sport was resurrected in Magdeburg, Germany, by Christian Georg Kohlrausch and his students in the 1870s.[2] Organized Men's competition was resumed in the late 19th century, and has been a part of the modern Summer Olympic Games since the first modern competition, the 1896 Summer Olympics. Images of discus throwers figured prominently in advertising for early modern Games, such as fundraising stamps for the 1896 games, the main posters for the 1920 and 1948 Summer Olympics. Today the sport of discus is a routine part of modern track-and-field meets at all levels, and retains a particularly iconic place in the Olympic Games.

Side view
 
Longitudinal section (schematic)

The typical discus has sides made of plastic, wood, fiberglass, carbon fiber or metal with a metal rim and a metal core to attain the weight. The rim must be smooth, with no roughness or finger holds. A discus with more weight in the rim produces greater angular momentum for any given spin rate, and thus more stability, although it is more difficult to throw. However, a higher rim weight, if thrown correctly, can lead to a farther throw. In some competitions, a solid rubber discus is used (see in the United States).
