Agility is one of the motor skills on which success in tennis performance depends, and aim this research was development validation a new test for assessing preplanned reactive agility young players. The sample respondents comprised 50 competitors with an average age 12.34 ± 1.22 years who were ranked up to 50th national association ranking 300th international Tennis Europe ranking. variables measured newly constructed tests assessment (CODS) (RAG), such way that subjects imitated specific movements tennis. It can be concluded (RAG) have high degree reliability. Additionally, assumption reliability will slightly higher (CA = 0.92 0.92; ICC 0.86 0.82) than 0.90 0, 89; 0.74 0.72) proven accurate. results also showed satisfactory validity. Thus, both show good correlation (p 0.6 p 0.55) T-test agility. noted all measurements, is, results, are normally distributed values skewness kurtosis within acceptable limits. We confirm sensitivity their applicability In conclusion, confirmed hypothesis extremely metric characteristics, especially test. paper proposed procedure players, significantly improve advance existing procedures, make more reliable precise.
