Abstract

Mental workload reflects the cognitive demands placed on individuals when performing tasks, particularly under pressure. As the esports industry continues to expand rapidly, understanding and managing the mental workload of esports athletes is crucial due to its impact on performance. While self-reported measures offer insights into players' subjective experiences, this study integrates these reports with objective physiological data - heart rate variability (HRV) and electrodermal activity (EDA) - to comprehensively assess mental workload. Data from 96 participants over 21 competitive matches were analyzed, revealing significant autonomic responses linked to cognitive demands. Key predictors of workload, such as Tonic Peak Count and Phasic Peak Count, were identified. Using machine learning models like support vector machine (SVM), workload classification achieved an accuracy of 81.97% and an AUC of 0.8824. These results underscore the value of combining physiological and subjective metrics to enable real-time monitoring and provide actionable insights for enhancing performance and well-being in high-pressure esports settings.
