Comparative Study On The Positional Efficiency Of Chinese Men's Basketball Team And Opponents In The 31th Olympic Games

The basketball technical statistics present in the mainstream basketball tournament in the field did not distinguish between the various objective position between the efficiency difference,but using a unified formula(mostly use the John Hollinger efficiency calculation system of well-known American ESPN media columnist)on the efficiency of all the players on the field of calculation and evaluation.This thesis mainly quoted efficiency formula calculated by Wu Luosheng,is based on the original technical statistics on the distinction between the center,forward and Guard in different positions in the competition efficiency,the actual effect is more for the same position players of a team of research units of time is reflected in the technical and tactical ability and defense the ability to use the calculated formula of Wu Luosheng the quantization efficiency with the position of the "Positional Efficiency" It has a high reference value for measuring the players1 different positions in the technical and tactical ability and offensive and defensive ability,and provides a certain theoretical basis for basketball players selection.In the big data environment,this study through the use of the location efficiency formula of the 31 Olympic Games men's basketball team Chinese A group and the other 5 teams were calculated,and the difference test of the Student's test.on the one hand by calculating the sum of rank and position are the efficiency of the group made the game score ranking to do comparison,calculation formula is feasible and effective the position of the basketball players and validate the efficiency.On the other hand,by comparing the differences of the position efficiency between Chinese men's basketball team and the team,we can help the Chinese men's basketball coaches analyze the weakness of the team.Finally come to the following conclusions:1?in the Olympic Games,the total efficiency of group level and final position of each team's ranking group phase similar to that position efficiency formula has certain reference value in the measure of ability and level of team player:2?the Chinese men's Basketball Guards scoring ability is poor,less assists in the game,there is no better ability to organize attacks,and rebounds and steals are lower than opponents.These are the main reasons that affect the low efficiency of the Chinese men's basketball guards.3?the main impact of China's men's basketball forward position efficiency is more mistakes and fouls,mistakes in this group up to 33 times,foul 71 times,compared with the team is the most.4?China's men's basketball team center position in the current game scoring ability is weak,free throw shot rate is low,poor physical confrontation,rebounding consciousness is weak,and blocked and less steals.
