Emotion regulation and psychological resilience sequentially mediate the association between training-related perceived stress and aggressive behavior among sport-major undergraduates

Within training-anchored contexts, perceived stress is linked to aggressive behavior partly through constrained emotion regulation and reduced resilience, consistent with a "regulation-first, resource-next" sequence. These findings suggest a stepped prevention focus on reducing salient training stressors while strengthening emotion-regulation skills and resilience; longitudinal and multi-source studies are needed to test temporal ordering and causal mechanisms.
