Abstract：
The coronavirus (COVID-19) pandemic led governments to adopt strict containment measures to avoid spreading the virus. These essential measures led to home confinement that influenced both the physical and mental health of populations. Physical activity plays a key role in preventing chronic diseases and promoting protective psychological factors. In the context of a lockdown, understanding the motives that guide people to enact physical activity is an important issue for public health. The present study aimed to evaluate the relation between autonomous motivation and physical activity, considering the role of behavioral intention and anxiety in a longitudinal moderated mediation model.
Italian participants (N = 86; meanage = 29.74, standard deviation = 9.74; female = 53.5%) completed a booklet composed of different questionnaires (motivation, intention, anxiety, and physical activity) 3 weeks apart.
The hypothesized model is supported by the evidence; both autonomous motivation and intention are direct predictors of physical activity. The results also show that the direct effect of autonomous motivation on physical activity is stronger in participants with low anxiety, while high levels of anxiety are a significant moderator of the intention-behavior relation.
In conclusion, a multidisciplinary approach should be promoting methods and infrastructures to permit people to adhere to physical activity, as a front line against any health emergency.

摘要：
冠状病毒（COVID-19）大流行导致各国政府采取严格的控制措施，以避免病毒传播。这些基本措施导致家庭禁闭，影响了人群的身心健康。身体活动在预防慢性病和促进保护性心理因素方面起着关键作用。在封锁的背景下，了解指导人们进行体育锻炼的动机是公共卫生的重要问题。本研究旨在评估自主动机与身体活动之间的关系，考虑行为意向和焦虑在纵向调节中介模型中的作用。
意大利参与者（N=86；均值=29.74，标准差=9.74；女性=53.5％）完成了由不同问卷组成的小册子（动机，意图,焦虑,和身体活动）间隔3周。
假设模型得到了证据的支持；自主动机和意图都是身体活动的直接预测因素。结果还表明，自主动机对身体活动的直接影响在低焦虑的参与者中更强。而高度焦虑是意向-行为关系的重要调节因素。
总之,多学科方法应该是促进方法和基础设施，以允许人们坚持体育活动，作为应对任何健康紧急情况的前线。
