Research Between The Physical Fitness Test Data And League Technical Data Of 2019 NBL League Players

The development of physical fitness test for professional league players in China has a history of more than 20 years.The physical fitness testing program is undergoing constant changes,and while making great progress in development,there are still some deficiencies.The purpose of the annual physical fitness test organized by the Chinese basketball association is to urge and test NBL club players to maintain physical fitness and skills during the off-season training,to have adequate physical protection,and to adapt to the coming new season of high intensity competition and achieve high personal efficiency value,to help the team to achieve better results.It has been five years since the work began in 2014,but the physical fitness tests have not been carried out smoothly in the past five years.In September2017,the Chinese basketball association(CBA)made a major reform of the physical test of the CBA professional league.Instead of participating in the physical test of all club players before,the test was conducted by randomly selecting two players from each team.The test contents and standards remain unchanged.There has been no reform of the NBL clubs' fitness tests,as the clubs' systematic training,the time and expense involved in the fitness tests and the health of players with potential injuries remain unresolved.In this paper,the samples of all four test results of players are divided into three positions: guard,forward and center for statistical purposes.Through correlation analysis,the relationship between test results of players in different positions and personal data indicators in competition is explored,so as to further reflect the relationship between test results and performance indicators in competition.The results show that:1.Through the analysis of 2 minutes intensity shooting scores of players in different positions,the scores of players in the forward position are relatively better.The correlation analysis was conducted between the test scores of players in different positions and theplayers' season hit ratio and the top 8 players in different positions in this test result.It can be seen from the analysis results that there is no significant correlation between the 2-minute intensity shot test scores of players in different positions and their individual season hit ratio.2.By analyzing three physical tests of players in different positions,players in the center position performed well in upper and lower body strength,while those in the center position performed poorly in speed endurance tests.Then the total scores of the top eight in the three physical fitness tests of players in different positions were analyzed in combination with the nine personal technical data indicators displayed by players in different positions during the season.The correlation analysis results showed that there was no significant correlation between the two sets of data.The correlation analysis between the top 20 players in the total score of physical fitness test and their personal efficiency value in the 2019 season shows that P=0.476,indicating that there is no significance between the two sets of data.It indicates that the performance of the athletes participating in the physical fitness test cannot reflect the individual efficiency of the players in the season to some extent.3.An analysis of the correlation between the physical fitness test results of players in different positions and the statistical indicators of league match data shows that there is no obvious correlation between the two in terms of data,but the physical fitness test contents formulated by the Chinese basketball association play a role in urging the daily physical fitness training of players.Therefore,it is suggested that players in three positions should be selected to participate in the test.
