| 摘 要： | 运用3D技术从动态支撑方式的频幅组合模式对速滑速度的影响关系进行了探讨。分析得出:由低速向高速滑行时,在步频与步速关系中,动态支撑方式遵循定点支撑方式的变化规律;但在步长与步速关系中,动态支撑方式却与定点支撑方式相反的结果。在频幅组合与步速关系中,步频是影响步速的决定因素。 |
| 关 键 词： | 步长 步频 步速 定点支撑方式 动态支撑方式 |

| Abstract: | The paper investigates speed factor affecting speed skating performance in the perspective of combination of frequency and stride in dynamic support by 3D technique.It puts forward that when skating from a low speed to a high speed,in the relationship between step frequency and step speed,way of dynamic support follows way of fixed-point support,but in the relations of step length and step speed,it is opposite.Step frequency is the determining factor affecting step speed in the relationship between combination of frequency and stride and step speed. |
| Keywords: | step length step frequency speed fixed-point support way of dynamic support |
