Behavioral Data Collection,Database Establishment And Preliminary Analysis Of Competitive Football

There are various researches on praxeology in the team competitive sports,among which football has the largest number of participants.Numerous studies have analyzed player discrimination and selection,psychological characteristics,training detection,visual responses,injury recovery mechanisms,and tactical analysis based on position information.However,there is little mention of quantitative data on players’ actions in real matches.This paper extracts data from the self-established football match database and explores dribbling and shooting actions.Based on 2923 shoot actions measured by PTT(Pass-Touch_Time)and TST(TouchShot_Time),we summarize that 58.69%of shoot action is done in 0～1(0.180±0.007s),18.91%of it in 1～2(1.422±0.013s),and only 10.30%of shoot happened in 2～3.Particularly,69.36%of goals are scored with average time of 0.168±0.013s,it reflects that time for shoot is very limited in the top leagues.Most Chinese players show lower TST time than the Europeans,but can’t get good results,which reminds the lack of domestic players’ ability to control the ball and dribbling.The TST time resulted goal,wide,saved and blocked is significantly different,TST_Goal<TST_Wide<TST_Saved<TST_Blocked.And PTT_Blocked<PTT_Goal<PTT_Wide<PTT_Saved,this may suggest the different rhythm among striker,defender,and goalkeeper.We define a arc measuring area with a distance of less than 23.60 meters from the goal line,analyze 2190 dribbling behaviors entering the arc from 18 leagues.Players’s Dt(dribbling time),D1(dribbling distance),D2(advancing distance)and DA(dribbling angle)are collectd from each attack.After comparing analysis from the perspectives of team,gender,age and professional,we then finally conclude a Goal Possibility Index(GPI)calculated by D2 and DtGoals=(1.19±0.22)Σmatch(Dt/1.54+D2/5.62)/GPIleague+(0.81 ± 0.13)(P<0.0001.In the UEFA Champions League(UCL),if the dribbling player passes the arc line for 1.7s and advances 5.7m,the team may score two goals after eight attacks.Results show that having players dribbling into the 26.3m area is the key to scoring.
