| Objective: The selection of athletes is the key problem of sports science research,and it is a hot issue in sports science research to explore the simple and accurate method of sports selection.The athlete's scientific selection is the athlete to obtain excellent athletic performance,climb the world champion the most powerful elements,and basketball player selection is excellent basketball athletes training system is a very important part.In recent years,in the field of sports science and material selection emerged more simple and reliable new indicators are not applied in basketball.The relationship between the long ratio of the athlete 's finger and the athletic level and the shooting percentage is studied for the question of whether the finger length can be used in the field of basketball player selection.Based on empirical research,enrich the selection of basketball players indicators for the scientific selection of basketball players to provide reliable theoretical data as a reference.Methods: This paper selected 31 national basketball players,the national two basketball players 55,not up to 165 professional sports students.Using the digital camera to take a sample of the long picture,through the Image-Pro Plus 6.0 image processing software to calculate the long.SPSS17.0 data analysis software was used to analyze the measured data.The subjects were from the age of 15 years to 25 years old,and the growth and development were not limited,and there were no hereditary diseases and congenital defects and acquired deformities.In order to avoid the interference and influence of ethnic differences,the ethnic minorities were screened and controlled in the research samples.The results showed that: 1.There is no gender difference between the same level of basketball players,and the gender ratio of basketball players is higher than that of male,and the gender difference between high level basketball players is not significant.2.The 2D: 4D,2D: 5D on the right side of the male athletes and the second-level athletes were lower than those of the ordinary group,the difference was significant,the female first-class athletes and the second-Level 2D: 4D,2D: 5D and the right side of the 2D: 4D,2D: 5D,3D: 4D,3D: 5D less than the ordinary group,the difference is significant.3.2D: 3D,2D: 4D,2D: 5D,4D: 5D,2D: 3D,2D: 4D,2D: 5D and 2D: 4D,2D: 5D on the right side of 2D Incremental trend of movement level.4.The shooting test score is higher with the 3D: 4D correlation coefficient on the right side of the male athletes and the second level athletes,but the difference is not significant.It is advisable for scholars to do more empirical research on basketball players' long work and special motor skills.2D: 4D,2D: 5D have a negative correlation with the motor grade and have significant correlation,and the correlation coefficient of male basketball players is greater than that of female basketball players.The correlation coefficient on the right side is generally higher than that of the left side,2D: 4D,2D: 5D is particularly significant.It is found that the 2D: 4D,2D: 5D on the right side is negatively correlated with the exercise level and can be used as a reference index for the selection of basketball players,and the relationship between the length of the basketball player and the athletic level is studied.In the basketball project on the right side 2D: 4D can be used as a key research object. |
