Motivation and moral attributes in sport

This research’s aim was to analyze the relation between self-determined motivation, sportspersonship and athletic aggression in volleyball players. Participated on this study 54 athletes between adults and youths from both genders. As measure instruments were used: Sport Motivation Scale (1995), Multidimensional Sportspersonship Orientations Scale (1997) and Bredemeier’s Athletic Aggression Inventory (1985). The data collection was performed during training. For the data analysis the Mann-Whitney test, Spearman correlation and Cronbach’s Alpha were used.
