This study verified the relationship between physical self-perception, exercise confidence, and adaptive performance according to prospective elementary teachers’ Myers-Briggs Type Indicators (MBTIs). First, in physical self-perception, extroversion (E) was higher than introversion (I), and thinking (T) was higher than feeling (F). In terms of exercise confidence, extroversion (E) was higher than introversion (I). In adaptive performance, extroversion (E), intuition (N), feeling (F), and judging (J) were higher than introversion (I), sensing (S), thinking (T), and perceiving (P). Second, concerning the physical self-perceptions of exercise confidence, competence pos itively influenced support, ability, preparation, and coaching, while physical strength positively but only partially influenced preparation. Third, in the physical self-perception of adaptive performance, competence positively affected adaptability, and physical strength positively af fected creativity, collaboration, and adaptability. Fourth, exercise confidence in adaptive perform ance, preparation and coaching had a positive effect on creativity and adaptability. Finally, support, ability, preparation, and coaching affected collaboration. However, while support, prepa ration, and coaching had a positive effect on collaboration, ability had a negative effect.
