| 摘 要： | 通过影像测量方法，探讨了速滑姿势与能量输出之间的关系。结果认为：功率与步频和滑行姿势密切相关；在滑行同一距离项目中，输出功率总量决定水平相近的运动员之间成绩上的微小差异：绝对意义的低姿势只能是躯干保持水平位置，而相对意义的低姿势以发挥下肢蹬伸力量为前提；高的能量输出主要是通过大量的蹬伸做功而产生。 |
| 关 键 词： | 滑行姿势 功率 输出功率总量 速度滑冰运动 |

| Abstract: | By means of video measurement,the authors probed into the relation between speed skating posture and energy output,and revealed the following findings:The power was closely related to stride frequency and sliding posture;in an event in which the athletes skate over the same distance,the parameter of total output power decided the slight difference of performance between athletes whose capabilities were very close;an absolutely low posture could only be the one in which the trunk maintains a level position,while a relatively low posture was used only to exert the striding power of lower limbs;high energy output was produced mainly by making a lot of strides to produce power. |
| Keywords: | sliding posture power total output power speed skating |
