Physical fitness is vital for good health and quality of life. On the other hand, it is declining, especially among university students, due to a sedentary lifestyle. Traditional fitness evaluation methods-using manual assessments and self-reported questionnaires-suffer from a lack of accuracy in identifying specific areas needing improvement. This paper proposes a physical fitness evaluation and prediction model using the integration of Covariance-Based Equation Modelling (CB-SEM) and Light Gradient Boosting Machine (LightGBM). It uses data drawn from an online survey targeting the assessment of key variables such as physical activity level, motivation to perform physical activity, measures of health status, and Body Mass Index (BMI). Next, CB-SEMis used to analyse the relations among latent variables, while LightGBM predicts the result of fitness (low, medium, or high). The LightGBM algorithm shows that the most important features related to physical fitness outcomes are physical activity levels and health measures. The integration of CB-SEM enhances the understanding of the causal relationship and thus increases the prediction accuracy. This model offers more efficiency and personalisation in evaluating fitness than traditional approaches do. The personalised results make it possible to provide relevant recommendations and track the individual\u2019s fitness improvement for better health outcomes. The LightGBM model attained a total prediction accuracy of 85.7% and showed a promising
ability to classify students into low, medium, and high fitness categories.<\/p>\n\n\n\n
