How does rest intolerance affect physical exercise? A dual-pathway mediation model of exercise adherence and psychological resilience

Rest intolerance exerts a direct inhibitory association on physical exercise, yet its indirect pathways exhibit dual-directional influences through 'behavioural persistence promotion' and 'motivation depletion inhibition', thereby obscuring the overall association. Exercise adherence serves as the most critical positive mediator, while diminished motivation quality constitutes a negative chain mechanism. Interventions targeting university students with high rest intolerance must concurrently guide healthy persistence strategies and enhance motivational autonomy alongside psychological resources.
