“…In agreement with the SDT perspective [ 1 ], needs satisfaction positively predicted PE grades, supporting findings from previous research [ 2 , 4 , 19 ]. Since the satisfaction of needs is related to positive outcomes, such as self-determined motivation [ 1 , 15 , 16 ], intentions towards physical activity [ 2 ], and enjoyment [ 3 ], it would be excepted that higher levels of autonomy, competence, and relatedness would impact higher academic success. Hence, those students who exercise volitional choice (e.g., choosing exercise combinations), who improve skills (e.g., learning how to dribble faster), and those who connect with peers (e.g., creating friendships during class) are able to engage and involve themselves more in PE classes, being positively associated with their academic grades, as seen in the present study.…”
