Research on the Workload of Referees in Youth Basketball Competition in China
This study aimed to explore the workload of basketball referees in different phases and quarters of the Chi-nese high school basketball league,providing a basis for the physical training,assessment,and development of bas-ketball referees.This study selected 36 national-level basketball referees from the Youth Basketball League in Zhe-jiang Province as participants.The study assessed various indicators,including heart rate,running distance,and speed,during different stages of competition(group phase,cross phase,and ranking phase)and in different quarters of each game.Two-way repeated-measures analysis of variance and post hoc comparisons were used to assess the impact and differences of competition phases and quarters on the internal and external loads of basketball referees.The results revealed that ①Quarters significantly affected the minimum heart rate(1st quarter<others,F=12.199,P=0.000),average heart rate(1st quarter<2nd quarter,F=5.179,P=0.005),and distance covered(1st quarter>others,F=8.206,P=0.001).The competition phase significantly affected the maximum speed(ranking phase>group phase,F=4.593,P=0.017).②The interaction of competition stages and quarters significantly affected the distance covered(ranking phase,1st quarter and 2nd quarter>4th quarter,F=2.718,P=0.017)and average speed(ranking phase:1st quarter>3rd quarter;1st quarter:group phase<ranking phase,F=2.643,P=0.024).The research conclusion suggests that referees experience lower physiological loads in the early stages of officiating high school basketball games,showing higher speed and distance covered in the ranking phase.
