| 摘要: |
| 运用文献资料法、数理统计法和逻辑分析法，对高水平跳跃运动员的比赛发挥问题进行研究。认为，比赛发挥是运动员通过参加比赛，对自身平时运动训练中所获得的专项竞技能力（竞技实力）的表现。比赛发挥受生物节律、竞技状态、心理因素、比赛性质、比赛环境等影响，具有不稳定性、相对性和可调性等特性。对两个奥运周期的调查显示，跳跃项目整体比赛发挥水平在94%-1016%之间波动，不同项目、不同年度的比赛发挥水平浮动范围存在差异。建议教练员围绕重大比赛，针对项目特点，调整运动员的竞技状态，提高重大赛事中的发挥水平 |

| Abstract: |
| By methods of literature, mathematical statistics, logical analysis, this article tries to study the issue of the athletic performance of high level jumpers. It is believed in this article that athletic performance represents the specialized athletic ability (or competitive strength) usually obtained in everyday training through participation in competitions, and it is affected by biological rhythms, competitive state, psychological factors, competition categories and competition environment with features of instability, relativity and adjustability. Survey on two Olympic cycle shows that overall performance of jumping events fluctuates between 94%1016%, performance fluctuation varies in different events and different years. It is recommended that coaches should concentrate on important competitions, and in connection with the characteristics of each events, adjustthe competitive state of athletes to enhance their performance level in the major competitions |
