Objective
Most research on the interplay of affective and physical feelings states with physical activity in children has been conducted under laboratory conditions and fails to capture intraindividual covariation. The current study used Ecological Momentary Assessment (EMA) to bi-directionally examine how affective and physical feeling states are related to objectively-measured physical activity taking place in naturalistic settings during the course of children’s everyday lives.
Methods
Children (N = 119) (ages 9–13 years) (52% male, 32% Hispanic) completed eight days of EMA monitoring, which measured positive affect (PA), negative affect (NA), feeling tired, and feeling energetic up to seven times per day. EMA responses were time-matched to accelerometer assessed moderate-to-vigorous physical activity (MVPA) in the 30 minutes before and after each EMA survey.
Results
Higher ratings of feeling energetic and lower ratings of feeling tired were associated with more MVPA in the 30 minutes after the EMA prompt. More MVPA in the 30 minutes before the EMA prompt was associated with higher ratings of PA and feeling energetic, and lower ratings of NA. Between-subject analyses indicated that mean hourly leisure-time MVPA was associated with less intraindividual variability in PA and NA.
Conclusions
Physical feeling states predict subsequent physical activity levels, which in turn, predict subsequent affective states in children. Active children demonstrated higher positive and negative emotional stability. Although the strength of these associations were of modest magnitude and their clinical relevance is unclear, understanding the antecedents to and consequences of physical activity may have theoretical and practical implications for the maintenance and promotion of physical activity and psychological well-being in children.
