Research on PHV％ in Relation to Test Performance of Indian Junior Football Players
OBJECTIVE:The study aims to explore the correlation between speed and agility based on health test results and analyze performance differences between high-performing and low-performing athletes across different age groups.METHODS:Using literature research method,experimental methods,and statistical analysis,this study tested 99 Indian adolescent football players aged 13 to 19 on football-specific speed,jumping,endurance,and agility.Peak Height Velocity(PHV)and Age at Peak Height Velocity(APHV)were used to assess the athletes'physical development.Correlation and regression analyses were conducted on speed and other test outcomes.RESULTS:(ⅰ)Grouping subjects by age and PHV％,no significant correlation was found between speed and agility test results.Performance differences between high-and low-performing athletes were observed in different test items within each age group.(ⅱ)In the later PHV％stages,vertical jump performance showed a clear correlation with agility test results;however,no significant correlation was observed between speed and agility,nor between endurance and agility.A significant correlation was found between jumping power and agility.CONCLUSION:PHV％,speed,endurance,and strength are differently related to performance in adolescent football players,providing insights for youth football training development in China.SUGGESTIONS:PHV％should be considered a key metric when designing training programs tailored to the developmental stages of adolescent football players.Training programs should clearly distinguish between speed and agility training objectives.Future research should expand the sample to include youth football players from various regions,genders,and cultural backgrounds to improve the generalizability and applicability of the findings.
