速度滑冰运动员应用指长比选材的研究

为满足速度滑冰项目科学选材工作的需要，对我国速滑运动员指长比（2D：4D）与运动成绩、血清睾酮、血红蛋白及血球压积等多种身体机能水平指标的相关性进行研究，探索指长比在速滑运动员选材中的作用。通过对黑龙江省冰上训练中心速滑运动员的手指长度及指长比的测量与分析，表明速滑运动员指长比与运动成绩相关性不显著，与血清睾酮等3项机能指标显著相关，即指长比（2D：4D）越高，相关血清睾酮（T）等3项运动机能指标越低，说明指长比（2D：4D）可以作为速度滑冰项目科学选材的重要指标被应用。

Research on Applying the Speed Skaters' Finger Length Ratio in the Talent Selection

In order to meet the needs of the speed skating talents' scientific selection, the paper has a correlational research on the speed skaters' finger length ratio (2D:4D) and other multiple indexes of physical function levels such as skating performance, serum testosterone, hemoglobin and hematocrit, and discusses the ratio action in the speed skaters' talent selection.After analyzing the measurement data of the finger length ratio of some speed skaters from Heilongjiang ice training center, the results show that the ratio's correlation is not significant to the skating performance, but is significant to the other indexes with higher the finger length ratio (2D:4D) and lower the other indexes, which tell us the finger length ratio (2D:4D) may be applied as an important index in selecting the speed skating talents.
