The aim of this study was to determine the relationship between morphological structures, motor performance and attention levels of adolescent basketball players with technical skills. 31 male basketball players (age = 13.1 ± 0.89) participated in the study voluntarily. Basketball player's body height, body weight, circumference measurements (calf and flexion biceps), diameter measurements (humerus and femur) and skinfold thicknesses (triceps, subscapular, suprailiac and medial calf) were measured. Body mass index (BMI) value was calculated. Somatotype values were determined by Heath-Carter somatotype method. Motoric performance tests (standing long jump, back strength, vertical jump, anaerobic power, push-up, sit up, throwing with medicine ball), basketball skill tests (dribbling and shooting) and attention test were applied to the basketball players. The relationship between basketball skills and morphological structures, motor performance and attention levels was determined using Spearman's Rank Correlation Coefficient. There were positive and mid level correlations between long jump, sit up and throwing with medicine ball values with shooting values of basketball players (rho = 0.46, p<0.01; 0.40, p<0.05, 0.47, p<0.01, respectively). There was a positive and mid level correlation between the dribbling skill and endomorphy and mesomorphy values of basketball players (rho = 0.49, p<0.01; rho = 0.45, p<0.05). A negative correlation was found between the dribbling skill and ectomorphy value (rho = -0.44; p<0.05). No relation was found between dribbling skills and attention and concentration values (p>0.05). As a result, it was determined that the technical skills increased with the increase of motoric performance values representing lower extremity, upper extremity and core strength. While increasing the endomorphic and mesomorphic values of the basketball players, the dribbling skills decreased, and the increase in ectormorphic increased dribbling skills.
