Participants completed the Mental Toughness Questionnaire, Dispositional Flow Scale, and self-rated subjectively perceived performance. Pearson¡¯s correlations between these measures revealed a significant, positive relationship between global MT and subjective performance ratings (r£¿=£¿.62, p£¿<£¿.01) and between global MT and all Dispositional Flow subscales (r£¿=£¿.67¨C.81, p£¿<£¿.05). Linear regression analyses found that MT subscales accounted for 64% of the variance in dispositional flow. Subjective performance ratings did not add significantly to the regression model. Overall, these findings suggest that MT may contribute positively to ironman competitors¡¯ and triathletes¡¯ exertion of the cognitive and emotional control necessary to experience flow and perform better.
