摘要:AbstractThe main objective of this study was to identify differences in self-confidence, perception of ability and perceived need of competence between winner and loser teams of young volleyball players. The study sample was composed of 173 Under-16 (M: 14.63, SD: 1.05) participants (74 males, 99 females). The T-test for independent samples showed statistically significant differences in self-confidence (F1,171= 3.95; p=.048; np2=.023), incremental perception of ability (F1,171= 10.28; p=.002; np2=.890) and perceived competence (F1,171= 5.451; p<.001; np2=.954) between players from winner and loser teams. Our results are supported by previous studies that showed highest values in winner teams than in loser teams.
