Abstract

The prints of the blood, eye, finger, and ear are essential method to identify the persons, where it is impossible to find two identical prints even of twins. Therefore, the print refers to the individuality which is the basic of training, diagnose, or educating athletes. The body segments are treated as a community of society, the output parameters of this community by the motion analysis are treated statistically for more understand how the body segment effect each other and the body center of gravity. Three good athletes in gymnastics were asked to perform the Round-off (gymnastics). Motion Track program was used to get the angular velocity for 14 segments plus the center of body mass. The skewness and kurtosis of the segments angular velocity were calculated. The segments were classified into categories according to a matrix between the skewness and kurtosis values. The results emphasis the differences in the technical prints between the three performances in the number of the cooperative, non-participant, and special segments. There is differences in the easiness and difficulty degree of performance.
