Abstract: 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 o f 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-lo op whorl, smaller ratio of the distance between the center of the loop and respective triradii in double-loop whorls and higher degree of symmetry.

Key words: Double-loop whorl, Gymnastic athlete
