Special Issue Information

Dear Colleagues,

ML and data mining have significantly transformed the fields of exercise, sports, and health research by providing sophisticated tools which can leverage large datasets to gain critical insights. In exercise science, ML algorithms can handle complex patterns in physiological responses, thereby assisting in developing customized training regimens. Predictive modelling significantly contributes to sports research, as coaches use these models to guide their decisions, prevent injuries, and assess individual game performance. In addition, ML enables the analysis of health data to identify risk factors and apply individualized interventions tailored to those factors. The use of ML and data mining in these areas enables researchers to uncover hidden connections that improve performance, injury prevention, and healthcare. With the increasing number of wearable technology and sensor devices, an enormous amount of data are produced, offering many new possibilities for improving the models and developing in-depth knowledge about human physiology. This interdisciplinary approach holds great potential to influence the shape of exercise, sports, and health research in the future, which will lead to precision, efficiency, and evidence-based decision-making.

Physical inactivity remains a major modifiable risk factor for non-communicable diseases and continues to exhibit marked socioeconomic and gender disparities in Latin America. Identifying robust and interpretable predictors of inactivity in nationally representative datasets is essential for informing public health strategies. This study compared a survey-weighted logistic regression model and an explainable machine learning approach (XGBoost) to predict physical inactivity among Chilean adults using data from the 2024 National Physical Activity and Sports Survey (ENAFyD; n = 5248). Models were evaluated on a stratified held-out test set (n = 1050) using weighted and unweighted area under the ROC curve (AUC), Brier scores, and calibration curves. Survey-weighted logistic regression achieved a weighted AUC of 0.801, while XGBoost achieved 0.797, demonstrating comparable discrimination. XGBoost showed marginally lower Brier scores, indicating slightly improved probabilistic calibration. Low socioeconomic status, female sex, lower monthly physical activity expenditure, limited facility access, and lower engagement with digital resources were consistently associated with higher inactivity risk. SHAP-style contribution analysis provided additional insight into feature-level influence within the machine learning framework. Overall, both approaches demonstrated similar predictive capacity, supporting the complementary use of classical regression and explainable machine learning for population-level physical inactivity research.
