Psychological and technological predictors of the physical activity intention-behavior gap: an explainable machine learning analysis

Psychological cognition and smart sports tools jointly predict the PA I-B gap. The study's conclusions are constrained by its reliance on self-reported measures and its cross-sectional design. Future research should adopt longitudinal or experimental protocols, supplemented by objective data from wearable devices, to delineate causal pathways and illuminate the finer mechanisms underlying the gap.
