| 目的：在高强度跑至力竭运动中，探讨外加紧身压迫对下肢运动特征和实际运动成绩的影响，以了解紧身服与运动表现之间的关系及其内在机理，为紧身装备的设计和使用提供参考。方法：随机选取12名男性田径运动员为受试者，分别以下肢轻度、中度、高度紧身压迫状态完成高强度跑至力竭测试，运用表面肌电和录像解析技术对主要发力肌群相关指标的数据进行采集，并进行统计分析。结果：①无氧和有氧混合供能模式的高强度跑至力竭过程中，中度外加紧身压迫对维持运动表现有一定程度的积极影响，而高度外加紧身压迫则会促进肌肉力竭；②无氧代谢供能模式的高强度跑至力竭过程中，高度外加紧身压迫更有助于促进运动表现；③运动员自身的运动技术等级水平越高，外加紧身压迫对下肢高强度跑至力竭运动特征的影响效应越明显 |

| Abstract: |
| Objective: In the highintensity exhaustive running exercises, this article discusses the effect of outside imposed tight compression on the exercise characteristics of lower limbs and on the actual athletic performance, in order to understand the relationship between tight sportswear and athletic performance and its inner mechanism and provide reference for the design and use of tight sports equipment. Methods: randomly select 12 male athletes as the subjects to finish highintensity exhaustive running exercises respectively with slight, moderate and great tight compression, use the methods of sEMG and video analysis for data collection of the main powering muscle groups, and then conduct statistical analysis. Results: 1)In the process of a combination of anaerobic and aerobic power mode, moderate tight compression has a certain degree of positive influence to maintaining physical activity, while great tight compression would promote muscle fatigue. 2) In the process of highintensity exhaustive running exercises with anaerobic metabolism power mode, great tight compression would be more helpful to improve athletic performance. 3)The higher the technical levels of athletes are, the more obvious the effect of outside imposed tight compression on the exercise characteristics of lower limbs is |
