The aim of this study was to determine effect of semester trainings applied children on some physical and bio-motoric features. 16 athletes at 14 age group making regularly swimming workouts at Antalya Kulaç Swimming Club were participated in research. In the beginning and end of research, flexibility, vertical jump and 50 m freestyle swimming tests were applied to determine bimotoric developments. As to body weight, anthropometric length, width, circle and underleather fat measurements were taken to determine change in physical features. Wilcoxon test in SPSS 15.0 for Windows package program was used in analyze of data obtained. End of committed training period, it was found that there were statistically significant increase at flexibility, vertical jump and 50 m freestyle swimming performance of participants (p<0,05). It has been found that the anthropometric environment, significant reductions in subcutaneous fat and body fat percentage values. It was established that there were decreases at significant level in circle, underleather fat and body fat percentage (p<0,05). It was established that significant decreases in values of circle, underleather fat and body fat percentage were occurred. While significant difference was found at shoulder, chest, chest depth, hip, knee and meta-tarsal width from width measurements (p<0,05), no significant difference found at elbow, wrist, meta-carpal and ankle width (p>0,05). Also, it was established that there was no significant change anyone of length measurements (p>0,05).As a result, it was revealed that swimming training programs applied termly to children develop swimming, force and flexibility performance and supply developments at significant level in body composition. Accordingly, i may say that termly swimming trainings develop both physical and biomotoric features of children. Article visualizations
