Shot physical training item correlation degree analysis based on grey system theory model

Jiang Zhang, Ying He

For shot exercise, training items have a variety of types. Combines with grey system theory, it analyzes shot putter physical training each training item, with an aimto reasonable arrange training items, reduce unnecessary training items, further optimize training items. By analyzing excellent shot putters physical abilities data in 2004 to 2008, making research on each training itemand shot total result relationship by utilizing grey correlation degree, using Matlab programs so as to get each physical ability training item and shot total result correlation degree, it is clear that shot putters performance maximum influences eight training items are full squat, 3kg glide, power clean, 4kg on site, clean&jerk, standing long jump, 30mtakeoff, 100mperformance
