| In order to analyze the preparation process of Jiangsu U18 women’s Football team for the 14 th National Games from the perspective of running performance,summarize the experience while exploring the shortcomings,and form a preliminary understanding of the running performance characteristics of Chinese youth women’s football team,this paper takes the running performance of Jiangsu U18 female football team during the preparation for the 14 th National Games as the research object,and uses literature method,observation and measurement method,mathematical statistics method and comparative analysis method to study the running performance in 29 friendly matches and 20 heavy-load training sessions during the preparation of U18 women’s football team in Jiangsu Province.The results show that:(1)The running performance of the Jiangsu U18 female football team in the winter training period friendly competition is generally close to the preparatory period of the preliminary round,and the total running distance.The heavy-load training session is mainly based on small-side games with equal numbers,supplemented by aerobic running without the ball,and the total running distance and acceleration and deceleration running times of athletes are higher than those of the friendly competition,but they are not as good as the friendly competition in the maximum running speed and the density of repeated high-intensity efforts.(2)The running performance of the Jiangsu U18 female football team in the friendly competition in the preparation period of the preliminary round reached the best level in the entire preparation process.In the heavy-load training session,the weak confrontation training with unequal numbers was removed,and the long-distance aerobic running was changed to a short-distance switchback run,the training intensity was higher than that of the winter training period,and the maximum running speed and the density of repeated high-intensity efforts still did not reach the level of friendly competitions in the same period.(3)In the friendly competition of the final preparation period of the U18 female football team in Jiangsu Province,the basic running performance and acceleration and deceleration running performance all regressed significantly,and the indicators related to repeated high-intensity efforts declined exponentially.The proportion of time spent in non-confrontational training events in heavy-load training sessions increased,and the running volume and intensity of athletes were lower than those of the previous two periods of heavy-load training sessions and friendly competitions at the same period.In some of the longer training sessions in some confrontational events,the running performance of athletes did not improve significantly,which reflected the unsatisfactory quality of training. |
