The softball throw is a track and field event used as a substitute for more technical throwing events in competitions involving Youth, Paralympic, Special Olympics and Senior competitors. The general rules for the softball throw parallel those of the javelin throw when conducted in a formal environment, but the implement being thrown is a standard softball, which resembles the size of a standard shot but is considerably lighter. The event was one of the standardized test events as part of the President's Award on Physical Fitness.〔(【引用サイトリンク】date=25 May 2006 )〕 It is an official event for ages 9–12 in the Hershey Youth track and field program.〔https://www.hersheystrackandfield.com/assets/pdfs/trackandfield/rulebook.pdf〕 Other meets include it as a beginners event.〔(【引用サイトリンク】title=WMA13.docx - Google Drive )〕 It is a youth event for the World Dwarf Games.〔(【引用サイトリンク】date=26 September 2012 )〕 Certain divisions of the Special Olympics throw a softball, specified in the rules as having a 30 cm circumference.
