Purpose: This study aimed to make an in-depth analysis of various reasons that gymnasts quitted gymnastics, prevent them from quitting gymnastics and provide basic data and information for the activation of gymnastics. Methods: Open-ended interview questions about ‘Gymnasts’ hard points’ and ‘circumstances which made them to want to quit gymnastics’ were used for two coaches, three active players, junior high school students and above and two players who had already quitted gymnastics. The conceptual structure of quitting was analyzed for 1,022 male and female gymnasts, junior high school students and above, registered on Korea Gymnastic Association in 2013 through experts’ conferences. Results: It was shown that gymnasts mainly quitted gymnastics due to several factors such as the risk of injury, authoritative guidance, hard training, unstable future, poor motivation, poor acting abilities (skills) and a lack of studies. Conclusion: The following measures should be taken to prevent gymnasts from quitting gymnastics: the control of training intensity, a guarantee of the right to learn, player-personalized guidance, the creation of a positive training atmosphere, adequate rest, the understanding of players’ difficulties through on-going counseling and observation, coaches’ efforts to develop players’ potential talents and institutional support to prevent players from quitting gymnastics.
