In recent years, Taekwondo poomse championships were added to already well-established WTF-style tournaments in competition fighting. Poomse, the imaginary fighting compositions, are used extensively for technical skill training and overall conditioning. Similar to the Taekwondo combatants, the poomse competitors undergo demanding preparations aimed at improving elements of technical performance. The intense training or overtraining has repeatedly been found to be associated with increase in mood disturbance and decrease in performance (e.g., Kellman, Altenburg, Lormes, & Steinacker, 2001). Little objective data, however, are available with Taekwondo practitioners. Thus, the present study assessed the relationship between the mood states and performance in elite poomse competitors. Specifically, the precompetitive mood affect and staleness, as measured by the Profile of Mood States Questionnaire (POMS), was investigated in 11 male and female black belt athletes (ages 16 to 40 years), members of the Croatian national team who took part in the European Technical Taekwondo Championship. Participants had their mood states with “how you feel right now” directional set examined on four occasions over a 3-week period. The last inventory was administered immediately prior to the competition. A series of one-way repeated measures analysis of variance tests revealed that the precompetition training regimen was not associated with significant changes in any of the POMS adjectives with the exception of Vigor (F3,30 = 6,56, p < .007) which decreased with the last two recordings. Similarly, no psychological effects from acute overtraining as indicated by Total Mood Disturbance scores were found. A well-known Morgan’s “Iceberg Profile” (1980), said to predict how well an athlete may perform in an upcoming competition, was observed with poomse performers yet it did not coincide with successful performance. None of the POMS measures were significantly correlated with competition ranking (p< .05). Instead, data with Croatian Taekwondo competitors suggest that these athletes’ profiles tend to follow a general concept in that they tend to have lower scores on negative affect and higher on positive affect than nonathletes. Since poomse training and performance involves elements of static nature and dynamic patterns where subjects alternate periods of high intensity exercise with periods of rest, poomse practitioners contrary to Taekwondo combatants may be less likely to meet the training volume threshold where the signs of overtraining and staleness become obvious. It was concluded that the poomse contestants operate in an unchanging and non-aggressive environment and, therefore, might be more amenable to psychological strategies beneficial to affective states.
