DIAGNOSIS OF SPORTS FATIGUE AND NUTRITIONAL INTERVENTION IN TRACK AND FIELD

ABSTRACT Introduction As a high-intensity physical sport, athletics can easily cause serious physical injuries and even psychological problems if not diagnosed after sports fatigue. Objective Study the relationship between sports fatigue and nutritional intervention in track and field. Methods One hundred track and field athletes in a province were investigated. Through literature survey, questionnaire survey, and other data testing, track and field athletes’ sports fatigue and nutritional status were analyzed to determine the necessary relationship between sports fatigue and nutritional intervention. Results The coach’s judgment of sports fatigue during athletes’ training is characterized by a lack of technical accuracy, leading to the decline of athletes’ physical recovery ability and aggravating sports fatigue to a certain extent. As a high-intensity physical exercise, athletics must diagnose sports fatigue in time and provide effective nutritional intervention. Conclusion The research shows that after high-intensity exercise, the diagnosis of sports fatigue in track and field athletes is of great importance in judging the athletes’ physical function, and scientific nutritional intervention plays an important role in athletes’ excessive physical function, improving their sports ability and relieving sports fatigue. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

摘要

引言：作为一项高强度体育运动，田径运动（track and field）若未在运动疲劳（sports fatigue）后及时开展诊断，极易引发严重的身体损伤乃至心理问题。

研究目的：探讨田径运动中运动疲劳与营养干预（nutritional intervention）之间的关联。

研究方法：选取某省100名田径运动员作为研究对象，通过文献调研（literature survey）、问卷调查（questionnaire survey）及相关数据检测手段，对田径运动员的运动疲劳状况与营养状态进行分析，以明确运动疲劳与营养干预之间的内在联系。

研究结果：教练员在运动员训练过程中对运动疲劳的判断存在技术准确性不足的问题，这会导致运动员身体恢复能力下降，并在一定程度上加重运动疲劳。作为一项高强度体育运动，田径运动必须及时对运动疲劳进行诊断，并辅以有效的营养干预。

研究结论：本研究结果显示，对田径运动员的运动疲劳进行诊断，对于评估运动员的身体机能具有重要意义；而科学的营养干预则对改善运动员过度机体负荷状态、提升运动能力以及缓解运动疲劳发挥着重要作用。

证据等级为II级；治疗性研究——治疗结局调查。
