Contribution

It introduces a novel EEG-based model for quantifying flow states and confirms its applicability across various sports and mental practices.

Findings

Significant correlation between EEG data and subjective flow reports

Psychological exercises improved flow during athletic performance

Model applicable to multiple sports and mental activities

Abstract

This article aims to explore the optimization of mental performance through the analysis of metrics associated with the psychological state known as flow. Several clinical studies have shown a correlation between the mental state of flow (characterized by deep and relaxed concentration and high psychophysical efficiency) and brain activity measured through electroencephalography (EEG). This study confirms such a correlation, focusing in particular on the sports field, where the flow state tends to occur more frequently. To conduct the study, Sporthype developed proprietary software that integrates several predictive models, in particular the Flow State Index (FSI), implemented within the Holytics system. An analytical protocol was established, including mental exercises and data collection sessions using the portable EEG device Muse, accompanied by a questionnaire to gather athletes' subjective perceptions of their mental state. The results revealed a significant alignment between the EEG data and the subjective experiences reported in the questionnaires, confirming the feasibility of detecting the flow state through prefrontal cortex activity. Furthermore, the psychological exercises included in the study protocol showed a tangible positive effect in enhancing flow during athletic performance. Flow improves performance through a more harmonious synchronization between mind and body. Although golf was the main context of the experimentation, the mathematical models developed within Holytics were designed to be applicable to a wide range of sports. In addition to golf, preliminary tests have been conducted in other sports such as tennis, as well as in non-sport contexts, including gaming and mental training practices such as mindfulness, concentration, and visualization.
