ABSTRACT

Anxiety sensitivity (AS; i.e. fear of arousal-related sensations) and impulsivity (i.e. tendency to act quickly without regard for longer-term consequences) represent risks for low physical activity participation. Theoretically, higher impulsivity may exacerbate the negative exercise behaviours of high AS individuals given the tendency of impulsive individuals to favour immediate (e.g. watching TV) over delayed rewards (e.g. the benefits of exercise). Our goal was to investigate the main and interactive effects of AS and impulsivity on physical activity levels at varying exercise intensities. Participants were 178 emerging adults (Mean age = 21.9; 68.8% women). Higher AS was associated with less engagement in vigorous intensity exercise. Moderator analyses revealed an AS x impulsivity interaction: high AS predicted significantly less engagement in moderate intensity exercise at low impulsivity levels and marginally more engagement in moderate intensity exercise at high impulsivity levels. Finally, higher impulsivity was associated with more time spent walking. Cognitive behavioural therapy for high AS, or teaching individuals with high AS to focus on immediate, external rewards of exercise, may help them engage in more physical activity. Given the wide-ranging physical and mental health benefits of exercise involvement, developing effective strategies to increase such involvement in high AS individuals is vital.

摘要

焦虑敏感性（AS；即害怕与唤醒相关的感觉）和冲动（即倾向于快速行动而不考虑长期后果）代表了低体力活动参与的风险。从理论上讲，鉴于冲动个体倾向于立即（例如看电视）而不是延迟奖励（例如锻炼的好处），较高的冲动性可能会加剧高 AS 个体的负面锻炼行为。我们的目标是研究不同运动强度下 AS 和冲动性对身体活动水平的主要和交互影响。参与者是 178 名新兴成年人（平均年龄 = 21.9；68.8% 为女性）。较高的 AS 与较少参与剧烈强度运动有关。主持人分析揭示了一个 AS x 冲动相互作用：高 AS 预测在低冲动水平下参加中等强度运动显着减少，而在高冲动水平下参加中等强度运动则略微增加。最后，更高的冲动性与更多的步行时间有关。对高 AS 的认知行为疗法，或教导高 AS 的人专注于锻炼的直接、外部奖励，可能会帮助他们进行更多的体育活动。鉴于运动参与对身心健康的广泛益处，制定有效的策略来增加高 AS 个体的这种参与至关重要。对高 AS 的认知行为疗法，或教导高 AS 的人专注于锻炼的直接、外部奖励，可能会帮助他们进行更多的体育活动。鉴于运动参与对身心健康的广泛益处，制定有效的策略来增加高 AS 个体的这种参与至关重要。对高 AS 的认知行为疗法，或教导高 AS 的人专注于锻炼的直接、外部奖励，可能会帮助他们进行更多的体育活动。鉴于运动参与对身心健康的广泛益处，制定有效的策略来增加高 AS 个体的这种参与至关重要。
