The aim of this work was to assess the youth gymnasts’ perceived sport outcomes regarding sport competence, confidence, connection and character in a competitive setting. The Gymnasts’ developmental outcomes were examined based on their age groups and gender. A total of 45 gymnasts (22 girls, 23 boys) between 12 and 18 years and their coaches (n = 9) participated in this study. The adapted and validated versions of a toolkit that measures the abovementioned athlete outcomes were utilized. The findings indicated the decreasing trend in the gymnasts’ developmental sport outcomes as they age. Regarding gender, boys scored higher in competence score, whereas girls had higher scores in character and connection (p < .05). The results of this study were discussed with the relevant athlete development and coach development literature and related suggestions were made regarding coaches’ professional development.
