The aim of this study was to analyse young basketball players’ attitudes towards fair play, winning, enjoyment, hard play and the acceptability of antisocial behaviour in the context of sports teams, such as cheating and gamesmanship. The sample included 230 adolescents (139 boys and 91 girls) with a mean age of 12.5 years (Range: 10-15 years; SD = 2.09 years). Results showed the importance of fun in sports, and the greater acceptance of gamesmanship and cheating among female players.
