BACKGROUND: Psychological researches on elite sitting volleyball (SV) players in international and national levels are extremely rare. Therefore, the aim of this study was to examine the quality of life (QOL) and mood states differences between elite SV players which qualified or not qualified for a national team. METHODS: Twenty-five elite Brazilian SV players, in two groups of the qualified (Q) players (N.=14; age: 30.6±6.7 years; BMI: 25.3±4 kg/m2), and not qualified (NQ) players (N.=11; age: 33.9±10.5 years; BMI: 24.1±4.3 kg/m2) volunteered for this study. They completed demographics, SF-36, and POMS questionnaires. Data were assessed by Mann-Whitney U-test, Pearson correlation, and a stepwise multiple linear regression analysis. RESULTS: The Q players had significantly higher weekly training hours (P=0.001), higher emotional role (P=0.003) and social functioning (P=0.009) scores, and lower depressed mood (P=0.021) compared with the NQ players. The weekly training (r=0.62), depression (r=-0.46), emotional role (r=0.61), social functioning (r=0.55), and mental component summary (r=0.54) variables were correlated with playing level. From these variables, only the weekly training hours had a significant regression equation for prediction playing level of the SV players (R2=0.642). CONCLUSIONS: We found that time for SV training could be the key factor that a player should have in order to be selected in the national team of SV. These findings may help SV coach and athletes for having expediency in their training programs.
