This study explored whether mental toughness, the capacity to maintain performance under pressure, moderated the relation between physical activity intentions and subsequent behavior. Participants (N = 117) completed the Mental Toughness Index and a theory of planned behavior questionnaire. Seven days later, physical activity was assessed using the International Physical Activity Questionnaire. Attitudes, subjective norms, and perceived behavioral control explained substantial variance (63.1%) in physical activity intentions. Intentions also significantly predicted physical activity behavior. The simple slopes analyses for the moderation effect revealed a nonsignificant intention-behavior relation at low levels of mental toughness. However, intentions were significantly and positively related to physical activity when mental toughness was moderate or high, suggesting that the development of a mentally tough mindset may reduce the gap between behavior and physical activity intention. Future research is needed to confirm these findings and apply them in the design of mental toughness interventions to facilitate physical activity engagement.
本研究探讨了心理韧性（即在压力下保持表现的能力）是否调节了体育活动意图与后续行为之间的关系。参与者（N = 117）完成了心理韧性指数和一份计划行为理论问卷。七天后，使用国际体育活动问卷对体育活动进行评估。态度、主观规范和感知行为控制解释了体育活动意图中相当大的变异（63.1%）。意图也显著预测了体育活动行为。调节效应的简单斜率分析显示，在低心理韧性水平下，意图与行为的关系不显著。然而，当心理韧性处于中等或高水平时，意图与体育活动显著正相关，这表明培养坚韧的心理心态可能会缩小行为与体育活动意图之间的差距。需要未来的研究来证实这些发现，并将其应用于心理韧性干预措施的设计中，以促进体育活动的参与。
