阿尔伯塔癌症运动（ACE）是一个在COVID-19期间从现场转向在线交付的运动肿瘤学项目。本研究的目的是了解参与者在不同交付方式下的体验。具体来说，收集了幸存者在锻炼方面的促进因素和障碍，交付方式的偏好以及针对行为改变的项目元素的经验。采用解释性顺序混合方法的回顾性队列设计。简要地说，57名参与者完成了调查，随后进行了19次自愿性面谈。大多数参与者表示更喜欢现场项目（58%），其次是在线项目（32%），没有偏好的人占10%。在线项目的锻炼存在更少的障碍（如通勤时间）（p < 0.01），但同时也有更少的促进因素（如社会支持）（p < 0.01）。从定性数据中提取了关于两种交付方式下参与者体验的四个主题。在障碍和促进因素方面的主要差异突显了在线环境相对更加便利，而现场环境则更具社会支持性。对于未来仅包含在线交付的工作，着重建设社会支持和社区共同体将是优化项目效益的关键。除了COVID-19大流行，这项研究的结果在我们力求将在线运动肿瘤学项目扩大到更多未得到服务的癌症患者群体时仍然具有相关性。

Alberta Cancer Exercise (ACE) is an exercise oncology programme that transitioned from in-person to online delivery during COVID-19. The purpose of this work was to understand participants' experiences in both delivery modes. Specifically, survivors' exercise facilitators and barriers, delivery mode preference, and experience with programme elements targeting behaviour change were gathered. A retrospective cohort design using explanatory sequential mixed methods was used. Briefly, 57 participants completed a survey, and 19 subsequent, optional interviews were conducted. Most participants indicated preferring in-person programmes (58%), followed by online (32%), and no preference (10%). There were significantly fewer barriers to (i.e., commute time) (p < 0.01), but also fewer facilitators of (i.e., social support) (p < 0.01), exercising using the online programme. Four themes were generated from the qualitative data surrounding participant experiences in both delivery modes. Key differences in barriers and facilitators highlighted a more convenient experience online relative to a more socially supportive environment in-person. For future work that includes solely online delivery, focusing on building social support and a sense of community will be critical to optimising programme benefits. Beyond the COVID-19 pandemic, results of this research will remain relevant as we aim to increase the reach of online exercise oncology programming to more underserved populations of individuals living with cancer.
