ANALYSIS AND STUDY ON THE CHARACTERISTICS OF DOUBLE-LOOP WHORL IN EXCELLENT GYMNASTIC ATHLETES

After observing dermatoglyphic patterns sample of 260 gymnastic athletes possessing double\|loop whorl again,dividing them into groups according to their sports achievements,and analysing the sample,we found a little difference between excellent and ordinary athletes, the main difference lies in:1.The two loop\|heads of double\|loop whorl are more integrate among the world\|level gymnastic athletes,and the loop\|head isn't easily confused with similar leaf\|loop whorl.2.Compared with the ordinary gymnastic athletes,the excellent ones has higher frequency of appearance of double\|loop whorl,higher frequency of long\|double\|loop among the double\|loop whorls.lower frequency of special big double\|loop whorl,smaller ratio of the distance between the center of the loop and respective triradii in double\|loop whorls and higher degree of symmetry.
