Personalized Emotion Regulation Strategies for Young Athletes

Applying the IZOF Framework

Abstract

This study examined the effectiveness of idiographically tailored emotion regulation interventions in adolescent tennis players, using the Individual Zones of Optimal Functioning (IZOF) model as a conceptual and methodological framework. Four male athletes aged 13 to 16, enrolled in a sport-études programme, participated in a three-phase protocol involving baseline assessment, intervention, and post-intervention follow-up during official competitions. Emotional and physiological profiles were assessed using idiographic scaling, psychometric instruments (TAS-20, ERQ, OMSAT-3), and self-evaluation measures. Results showed that participants who achieved greater emotional alignment with their IZOF-defined optimal zones reported improved self-perceived performance. However, interindividual variability emerged, particularly among those with elevated alexithymia scores. Although statistical effects were limited, descriptive and visual analyses suggested functional links between emotional congruence and competitive outcomes. The findings support the feasibility of IZOF-based interventions in youth sport and highlight the importance of personalisation, emotional awareness, and developmental factors in designing effective psychological strategies. Methodological limitations and directions for future research are discussed.
