Research Impact: Physical activity (PA) can improve sleep quality and fatigue, but the potential moderating effect of sleep quality on associations between PA and feelings of fatigue among adolescents is unknown. This study showed that sleep quality moderated the association between PA and feelings of fatigue among 481 adolescents. A dose-response was suggested among adolescents with poor sleep quality such that poor sleepers with low PA reported greater feelings of fatigue compared to both poor sleepers with moderate PA and poor sleepers with high PA. Poor sleepers with moderate PA reported greater feelings of fatigue compared to poor sleepers with high PA.
