Brief Summary

Ultra-endurance races (ultra-marathons) take place under extreme environmental conditions, over long distances, involving prolonged physical activity and multiple psychological and physiological challenges. These extreme conditions expose runners to a wide range of emotions-both pleasant and unpleasant-that can influence their performance, fatigue, and perception of exertion. Emotional intelligence and emotional regulation appear to be key determinants of emotional trajectories and performance in these contexts. Previous research shows that high levels of emotional intelligence and adaptive emotional regulation strategies are associated with functional emotional trajectories and better performance, whereas maladaptive strategies are linked to dysfunctional emotional trajectories and reduced performance. Furthermore, defense mechanisms constitute a complementary approach to emotional self-regulation. They can be adaptive or maladaptive and influence how runners cope with emotions and psychological stressors during competition. Longitudinal studies conducted to date have primarily explored post-race emotional trajectories in relation to emotional intelligence, without examining the impact of defense mechanisms on emotional dynamics during the race. Furthermore, few studies have examined the mediating role of emotional intensity between emotional regulation and perceived performance, and even fewer have adopted an approach that integrates physiological indicators such as heart rate or heart rate variability. Thus, this study lies at the intersection of sports psychology, emotion, and physiology, and aims to fill these gaps by exploring:

  1. 1.the influence of defense mechanisms on emotional dynamics and physical and mental fatigue during an ultra-endurance race, and
  2. 2.the mediating role of emotional intensity on the relationship between emotional regulation and perceived performance.

Outcome Measures

Primary Outcomes (1)

  • Defense mechanisms will be assessed before the race using the Defense Style Questionnaire - 26 (DSQ-26). Emotional intensity will be assessed before the race, during the race (at the 25-, 38-, 48-, and 56-kilometer marks), and at the finish line.

    Defense Style Questionnaire - 26 (DSQ-26). Scale from 1 to 6, with 1 being "never" and 6 "always".

    Before, during (kilometers 25, 38, 48, and 56), and at the finish line (80th kilometer) of the "Ecotrail de Paris Ile de France 80 kilometers" ultra-trail race taking place on March 21, 2026.

Secondary Outcomes (3)

  • Evaluation of physical and mental fatigue before, during and after the race

    Before, during (kilometers 25, 38, 48, and 56), and at the finish line (80th kilometer) of the "Ecotrail de Paris Ile de France 80 kilometers" ultra-trail race taking place on March 21, 2026.

  • Exploration of the relationships between emotional regulation strategies and runnners' perceived performance

    Before, during (kilometers 25, 38, 48, and 56), and at the finish line (80th kilometer) of the "Ecotrail de Paris Ile de France 80 kilometers" ultra-trail race taking place on March 21, 2026.

  • Exploration of emotion regulation strategies and runners' perceived exertion

    Before, during (kilometers 25, 38, 48, and 56), and at the finish line (80th kilometer) of the "Ecotrail de Paris Ile de France 80 kilometers" ultra-trail race taking place on March 21, 2026.
