Machine Learning Prediction of Long Jump Performance Based on Biomechanical Factors
摘要
This study investigates the use of machine learning to predict long jump performance based on biomechanical features. Data from nineteen biomechanical variables collected from elite long jumpers were analyzed, with machine learning models including Random Forest, CatBoost, Gradient Boosting, and XGBoost used for performance prediction. Feature importance analysis, conducted using the Random Forest model, highlighted key predictors such as gender, horizontal velocities during critical strides leading up to take-off, and vertical velocity at take-off. Among the models tested, XGBoost demonstrated the highest accuracy, achieving an \(\text {R}^{2}\) of 0.9454, MAE of 0.1552, and RMSE of 0.1791. These findings emphasize the pivotal role of biomechanical factors in predicting performance and offer data-driven insights for enhancing long jump outcomes for athletes and coaches.
