Research on the Evaluation System of Endurance Sports Ability of Cross-country Runners

This paper examines the evaluation of ability in human endurance sports. First, it presents the formula used to calculate the Endurance Index. Second, the k-means clustering algorithm is used to analyze different cross-country running competitions to provide accurate measurement of the contestants. The finish times of randomly selected contestants were predicted, and the average accuracy of the predictions was more than 94%. This study provides a way for contestants, organizers, and the sports industry to predict the duration of running events.
