The Impact of Physical Activity on Negative Affect and Sleep Quality in Adolescents: Network Analysis.

BACKGROUND

Negative affect may trigger a variety of psychological and behavioral problems, while physical activity has been shown to reduce negative affect. However, the underlying mechanisms remain unclear. The aim of this study was to investigate the relationship between physical activity and negative affect, specially examining the role of sleep quality in the relationship.

METHODS

Cross-sectional design was adopted in this study. A total of 557 adolescents participated in the study, completing self-reported questionnaires on physical activity, sleep quality, and negative affect.

RESULTS

Sleep quality mediated the relationship between physical activity and negative affect. There was a positive correlation between "exercise" and "sleep quality" and a negative correlation between "sleep restfulness" and "feeling bored".

CONCLUSION

This study uncovered the underlying mechanism of physical activity associated with negative affect, offering significance for the prevention and intervention of depression and anxiety disorders.
