Research on the Development of a Specialized Physical Fitness Index System for Junior Basketball Players
Specialized physical fitness is a crucial component of the athletic abilities of junior basketball players and significantly impacts their sports performance.This study uses literature research method,the Delphi method,principal component analysis,and mathematical statistics to establish specialized physical fitness indicators for junior basketball players.The results revealed that the assessment indicators for the specialized physical fitness of junior basketball players consist of four primary indicators and nine secondary indicators.The primary indicators and their respective weights are as follows:motor quality(0.37),body morphology(0.25),physical function(0.2),and psychological function(0.18).The secondary indicators and their respective weights include:height(0.15),cardiorespiratory index(0.13),reactive agility(0.13),lung capacity/body weight(0.12),approach single-leg jump-touch height(0.11),visual reaction time(0.11),ankle circumference/heel tendon length ×100(0.09),fingertip-to-height ratio(0.08),and T-test(0.08).
