运动员竞赛焦虑是影响其比赛成绩的关键因素，焦虑也是由多方面因素构成的，随着大赛的临近，运动员也会出现不同程度的睡眠问题，基于此提出本研究，以期能够找出影响运动员睡眠和竞赛焦虑的原因，为运动员在赛场上提高运动表现和竞技状态提供一定依据。本论文主要采用文献资料法、问卷调查法、数理统计法等研究方法，以北京市代表队22名啦啦操运动员为研究对象，对第一届全国学生青年运动会北京市啦啦操代表队睡眠与竞赛焦虑之间的影响因素进行分析，分别从睡眠质量情况、竞赛焦虑分析以及睡眠与竞赛焦虑的相关性分析得出以下结论：
北京队啦啦操运动员睡眠情况从整体上看不存在特别严重的睡眠问题，运动员睡眠困难与每天摄入咖啡因、睡前使用手机情况有较大关系，比赛时旅行因素也是影响运动员睡眠的重要因素。竞赛焦虑情况从整体上看差异性较小，不同运动年限以及不同运动等级的运动员，竞赛焦虑特征没有明显的随着运动年限越高或运动等级越高而下降，反而有升高的趋势，同时可以发现认知焦虑与躯体状态焦虑是相互影响的，当运动员出现认知焦虑时，其躯体焦虑也会随之升高，但随着运动员自信心的提高，其焦虑水平也会随之下降。通过对睡眠和竞赛焦虑的相关性进行分析，发现睡眠与竞赛焦虑呈正相关，对睡眠不满意的运动员在认知状态焦虑和躯体状态焦虑的得分较高，运动员对睡眠满意时其在认知和躯体状态焦虑程度会低于睡眠不满意时得分，状态自信得分会高于睡眠不满意时得分，同时发现睡眠障碍问题对运动员状态自信心存在一定影响。

Athletes' competition anxiety is a key factor affecting their performance, and anxiety is also composed of various factors. With the approach of the competition, athletes will also have different degrees of sleep problems, based on which this study is proposed, in order to be able to find out the reasons affecting athletes' sleep and competition anxiety, and to provide a certain basis for athletes to improve their sports performance and athletic performance on the field of competition. This paper mainly adopts the research methods of literature, questionnaire survey and mathematical statistics, and takes 22 cheerleading athletes of the Beijing Cheerleading Team as the research object, and analyses the influencing factors of sleep and competition anxiety of the Beijing Cheerleading Team in the 1st National Student Youth Games, and draws the following conclusions from the analysis of sleep quality, competition anxiety and the correlation analysis of sleep and competition anxiety, respectively:
The sleep situation of Beijing cheerleading athletes as a whole does not have particularly serious sleep problems, and the athletes' sleep difficulties have a greater relationship with daily caffeine intake, the use of mobile phones before going to bed, and the travelling factor during the competition is also an important factor affecting the athletes' sleep. The competition anxiety situation is less different from the overall view, the competition anxiety characteristics of athletes with different years of sports experience and different sports grades did not obviously decrease with higher years of sports experience or higher sports grades, but had a tendency to increase instead, and at the same time, it can be found that the cognitive anxiety and the somatic state anxiety are interacting with each other, and when athletes have cognitive anxiety, their somatic anxiety will be elevated as well, but with the athletes' self-confidence increases, their anxiety level will also decrease. By analysing the correlation between sleep and competition anxiety, it is found that sleep and competition anxiety are positively correlated, athletes who are dissatisfied with sleep have higher scores in cognitive state anxiety and somatic state anxiety, athletes who are satisfied with sleep have lower scores in cognitive and somatic state anxiety than those who are dissatisfied with sleep, and the score of state self-confidence is higher than that in the case of dissatisfied sleep, and at the same time, it is found that sleep disorders have some influence on athletes' It was also found that the sleep disorder problem has some influence on the athletes' state self-confidence.
