Wearable devices and mobile applications (hereafter referred to as apps) used in sport and physical activity have widely changed the way sport is practised. However, experts still understand little about the antecedents of tourists’ sport apps use. Drawing on the theory of reasoned action, this study examined attitudinal and norm-based factors that influence users’ continuance intention towards sport apps as predictors of use in trips. A questionnaire was designed based on the existing literature in order to collect the relevant data from centres and places for doing sport. The final sample consisted of 362 sport practitioners and users of sport apps, whose responses were used to test the model. The results indicate that all attitudinal factors (i.e. performance expectancy, effort expectancy, perceived satisfaction, perceived enjoyment and perceived gamification) and norm-based factors (i.e. social influences) affect users’ continuance intention towards Smart Internet of Things sport apps. In addition, the respondents’ continuance intention towards these apps affects their sport apps use in trips. Theoretical and managerial implications for the tourism industry are discussed.

体育和体育活动中使用的可穿戴设备和移动应用程序（以下称为应用程序）已大大改变了体育锻炼的方式。但是，专家们对游客使用体育应用程序的前提仍然知之甚少。基于合理动作的理论，本研究研究了基于态度和基于规范的因素，这些因素影响用户对运动应用的持续使用意图，作为旅行中使用预测的指标。在现有文献的基础上设计了一份问卷，目的是从进行运动的中心和地点收集相关数据。最终样本由362位体育从业者和体育应用程序的用户组成，他们的回答用于测试模型。结果表明，所有态度因素（例如，预期绩效，预期工作量，知觉满意度，感知的享受和感知的游戏化）以及基于规范的因素（即社会影响力）会影响用户对智能物联网运动应用程序的持续意愿。此外，受访者对这些应用程序的持续使用意愿会影响他们在旅途中使用运动应用程序。讨论了对旅游业的理论和管理意义。
