The Research On The Characteristic Of Dermatoglyph Of Half-pipe Snowboard Athletes In China

Halfpipe is emerging in our country as an event of the winter snow. With the rapid development of halfpipe, there are more in-depth exploration and research from all aspects. Dermatoglyph as a particular human trait, with genetic, individual-specific and life-long stability of the same characteristics, is exposed in vitro genetic factor. Through the research of halfpipe athletes'dermatoglyph, we can early predict the intellectual and physical of athletes'strength, agility level of athletic ability and some hereditary diseases. The research will contribute to the system of scientific research system, and contribute to good back-up training to help China's halfpipe for sustainable development projects.In this paper, we make use of the literature method, specialist intervien method, measurement method and mathematical statistics method on the research of our country halfpipe athletes'dactyl gram, palm prints, foot patterns. We make point-by-point comparison of the date of halfpipe and technical ability event, such as gymnastics, martial arts.The results show that: (1) The characteristic of dermatoglyph of halfpipe Athletes in China show that ulnar loop(Lu)and whorl double(Wd) pattern appear high rate, the a-bRC of women athletes are more, atd angle is big, exchange birthplace hands fewer, low appear rate of short bend muscle line, fewer thenar pattern and hypothenar pattern of hand thumb root segment , area 4th finger is hight , high profile women's Sichuan font appears the high rate of hand, foot ball thumb District frequency patterns were Ld>W>Lt>At, no S-shaped arch fibular there. (2) Compared with the ordinary people, dermatoglyphics of seven indicators are differences, they are: ulnar loop(Lu), radial loop( Lr), whorl spiral(WS), whorl double (Wd), atd angle, bend muscle line, area 4th finger. (3) Projects with skills (gymnastics, martial arts) athletes'dermatoglyphy in atd angle, the total finger ridge count (TFRC), the thumb of occurrence of whorl double, a-bRC both the number of research indicators and differences in common. (4) of the national team athletes dermatoglyphics ulnar loop (Lu) the mean rate,the number of whorl double rate,TFRC,a-bRC,atd angle,area 4th finger,from other athletes.Therefore, the characteristic of dermatoglyph of Chinese halfpipe Athletes are different from the average person, and are also different from technical event athletes, and national team athletes have separate dermatoglyph.
