摘要:Participation motivations are important for youth basketball players (YBPs) keep engaged in their practices and competitions. This study explored what are the crucial factors that actually motivate YBPs engage in practices and competitions continually. Using data from a sample of 101 YBPs, results indicated that the top six motivation factors (MFs) among total of 19 MFs were: ‘Content and unique-value’, ‘Fun and get rid of boredom’, ‘Contest winners’, ‘For healthier’, ‘Enjoyment and happiness’, ‘Shape body’; while the secondary high impact MFs included: ‘Improve health’, ‘Reduce pressure’, ‘’Make new friends’, ‘Become a professional-player’, ‘To my biography’, and ‘Become a coach”. The MANOVA results revealed: no significant difference in ‘Gender’ aspect, however, significant differences were found in ‘Support-by’ and ‘Goal-setting’ aspects. In conclusion, gender is not the determination aspect; but ‘Support-by’ and ‘Goal-setting’ are. Participants who support-by school possess higher motivations than those support-by parent; set ‘goal for professional’ players possess higher motivation than those set ‘goal for non-professional’ players. Reasons behind of these findings were exhaustively discussed.
