N2  - OBJECTIVE:  To understand the predictors and consequences of adolescent moderate-to-vigorous physical activity (MVPA) and sedentary behavior in nearly real-time. <br><br>METHODS:  Participants were 26 adolescents (Mage = 15.96, SD = 1.56) who provided 80 self-reports of subjective states and continuous objective reports of MVPA and sedentary behavior over 20 days. <br><br>RESULTS:  Random effects were observed for all of the models with affect and feeling variables predicting MVPA. There was a negative fixed effect for within-person positive affect and sedentary behavior and the inverse association for negative affect. Within-person MVPA was a significant positive predictor of positive affect and energy. There was a random effect for within-person MVPA and fatigue. There was a significant random effect for within-person sedentary behavior predicting positive affect. Within-person sedentary behavior was a significant negative predictor of energy. <br><br>CONCLUSIONS:  Findings highlight the importance of the intrapersonal nature of the associations among subjective states and physical activity.<br><br>© The Author 2017.
