ABSTRACT: This study is intended to examine the impact of pre- competition anger on self- confidence and success
of volleyball players in Premier League and its relation with experience of athletes. Statistical population in this
investigation includes all (15) present teams in Iranian Volleyball Premie r League (2009-10) among of which some
volleyball players (n=118) were elected randomly in hand as statistical sample for this study. In order to evaluate
rate of anger among sample group, Spielberger State- Trait Anger Expression Inventory (STAXI) was adopted in
which the subscales of Emotional States of anger (chronic anxiety), State Anger (anxiety), and Trait Anger
(Expression of Anger) are evaluated in 4- value LIKERT Scale and Villay Sport Self- Confidence Questionnaire (1986)
was utilized to assess athletes’ self- confidence. With respect to team’s status in table of competitions, rate of
volleyball players’ success was evaluated at the end of the given league season. To analyze data after adoption of
Kolmogorov- Smirnov Test and making sure from data normal distribution (p>0.05), Multiple Analysis of Variance
(MANOVA Test, Tukey Post Hoc Test, and Pearson’s Correlation Test were used for data analysis at significance level
(p≤ 0.05). The result of study indicated that there is significant difference i n acute anxiety subscale between toplower rank teams with middle- lower rank teams (p≤0.05; F=3.48). Similarly, a significant difference was observed
among all three team ranks in subscales of chronic anxiety (p≤0.05; F=2.62) and expression of anger/ Trait Anger
(p≤0.05; F=4.06). But no significant difference was seen in subscale of self- confidence between top- middle ranks
with middle- lower ranks in these teams (p≤0.05; F=2.51).
