Abstract: Since the theoretical mode of the network structure of competitive ability was proposed,the study of its normal formulas has received much concern.Based on the process and result of "the study of the breakthrough in national youth fencer's primary training" which was the key issue of General Administration of Sports,this paper studied the training theory and came out with a methodology explanation.The main conclusion was universality,using Excel and Matlab,can build up a theoretical mode of network structure of each program,level and time feature.Special physical fitness,coordination and competitive performance are central points of women epee fencers' network structure of competitive ability.They play an indispensable rule in developing and upgrading the network structure of competitive ability;special physical fitness is a central point of national women epee fencers' network structure of competitive ability.The network structure of competitive ability is relatively stable,but is vulnerable under selective attack.Special physical fitness,coordination,competitive performance and thinking ability are central points group of women youth epee fencers' network structure of competitive ability.The network structure of competitive ability is poor.Using "contracture" to develop competitive ability is the key to youth sports training.
