The Influence of between the polymorphisms of vitamin D receptor gene and isokinetic peak torque and angle of peak
torque was examined in 40 Short tract skaters. Genomic DNA was extracted from Blood samples and vitamin D receptor
genotypes were determined with the established restriction Fok Ⅰ emzyem methods. The peak torque, joint angle at peak
torque and time to peak torque of the dominant limb in concentric knee extensors and flexors were measured using
Humac-Norm isokinetic dynamometer. The difference in peak torque, joint angle at peak torque, time to peak torque between
VDR genotype groups was analyzed using one-way ANOVA(SPSS version 12.0 for windows). The vitamin D receptor ff
genotype group showed significantly higher peak torque in concentric knee flexors than Ff, FF genotype group(p<.001). The ff
genotype group joint angle at peak torque showed significantly higher in concentric knee flexors than Ff, FF genotype
group(p<.05). If progress in a person-specific VDR gene polymorphism is considered to be a more positive influence on the
development of Korean short track speed skating.
