This paper uses the method of literature study,literature metrology method,mathematical statistics and statistical co word analysis to anlyse key words about the theme of track and field in sports 12(Peking University Edition)core journals during 1986-2016(published)and research hot spot and distribution of China.Research shows some results:(1)The number of track and field documents in China is a similar normal distribution curve.The rise from1996 to 2005 turns obviously,with the peak in 2003.track and field the number begin to decrease because of many branches of science and technology,with improvement of technology is gradually mature and athletics.(2)Field literature is the main camp track in the journal class.Chinese sports science and technology bears the important carrier of track and field documents in many non journal core periodicals.Journal periodicals are to achive eacademic exchange and issuie research results of track and field.Journal of Beijing Sport University and Journal of Xi'an Physical Education University are examples.Non journal periodicals have their own emphases because of their different purposes.Chinese sports science and technology tends to publish track and field articles.(3)The hot spots of track and field have different emphases.From 1986 to 1995,hot spots focus on the level of technology,the referee work,sports,athletics,track and field teaching,running speed,track and field,the world athletics championships,physical fitness,sports training,athletes,after kicking,special training and athletics.In from 1996 to 2005 hot spots focus on middle and long distance running physical quality training method,approach,frequency and velocity,finally forced,hurdles,high jump,javelin,walking,ten men,seven women Almighty Almighty,vault,shot,running speed,man,short run,100m run,grey theory.In from 2006 to 2016 hot spots focus on sports biomechanics analysis,Olympic Games 110m,bar,long jump,Liu Xiang,body quality,speed,javelin,shot put,sports training,colleges and universities,finally forced,take-off techniques,high jump,pole vault,investment Throwing,men,jumping and marathons.(4)The distribution pattern of scattered points have some changes,following regular pattern that objects develop from immaturity to maturity.The beginning is central point(1986-1995 years),and then the central agglomeration distribution(1996-2005 years),and the last is aggregated and distributed(2006-2016 years).The development of new techniques,new methods and new records push deep studies of track and field techniques,athletic training,track and field events and track and field teaching.
