At this study, it was aimed to determine the antropometric proporties of 15 years olded children. At this study, 37 football payer, 51 fitness and 51 sedantery, totally 139 children were joined to study volunteerly. Age, height, weight, sitting hight, total arm lenght, circumference (shoulder, waist, chest, thigh, calf, biceps extantiyon, biceps flexion) and somatotype (endomorph, mesomorph ve ectomorph) parametres were measured. For statistical analysis, One-Way Anova and Tukey HSD test were performed by packege programme which was called SPSS According to comparement between groups, no meaningful differences were found at height, sitting hight and total arm lenght parametres at the level of p>0,05. while meaningful differences were found waist, chest and calf circumference parametres at the level of p<0.05, meaningful differences were found weight, shoulder, thigh, biceps extantion ve flexion circumference, endomorph, mesomorph ve ectomorph parametres at the level of p<0.01. As a result of the study; Long term excercise which is every type, has posistive effect on children’s antropometric composition and somatotypes. However, this effect is not clear enough during growth and improvement period of children.
