All data were analysed using SPPS for Windows (v. 20.0). The present study had a cross sectional design involving two age groups: U13 and U18. First, two canonical discriminant analyses were used to investigate relevant physical performance measures in karate, judo and taekwondo for both age groups. In those analyses, belonging to either of three different sports was the grouping variable and the independent variables were the test results obtained from the five anthropometrical, six physical and three motor coor- dination characteristics.
