This work aimed to elicitation the speed of swimming computing the time of performance divided on the distance. Therefore, the speed meaning their achievement and thereafter understanding the relationship between kinematic variables and achievement that lead to final focused recommendations using descriptive method, samples of sixty students were selected intentionally from forth year, school of physical education, Duhok with good performance in swimming. Scientific observation, questionnaire, test, analysis, and measurement were used for data collection, certification of the scientific observation was carried out by two camera one above and other under the water inside glass box closead tritely placed in front of the performance (10 m in the middle of race). The best photos transferred to laptop for application Maxtraq program for kinetic analysis. Results revealed non ? significant correlation between some biokinetic variables with achievement i-e weakness of sampling technique. Free-style swimming requires body's extension through extending of hips which showed significant correlation with achievement. Comparable correlation of elbow with achievement means necessity of hand extension to pull more water. However, increasing of leg extension when the right arm enter the water lead to less resistance on the body. Once the right arm enter water, the left hand must gradually extending under water until approach to full extension beside the hip. Thus, inverse considerable correlation resulted between leaf forearm with horizontal line of body Key Words:-Bio Kinematics, Achievement, free style, swimming.
