新冠肺炎疫情期间，在线健身服务作为“智慧抗疫”的重要组成部分受到了业界和学界的广泛关注。为了进一步探究在线健身服务持续使用意愿的影响因素，该文对技术接受模型（TAM）和任务—技术匹配模型（TTF）进行了整合，通过网络调查和数理统计等研究方法对用户持续使用在线健身服务的影响因素进行了实证分析。结果表明： （1）影响用户持续使用意愿的内外部因素主要包括感知有用性、感知易用性、感知趣味性、任务特征、技术特征和任务—技术匹配度6项；（2）感知有用性、感知易用性、感知趣味性以及任务—技术匹配度对用户持续使用意愿均有显著正向影响；（3）任务特征和技术特征显著正向影响任务—技术匹配度，感知易用性则显著正向影响感知有用性，而感知易用性则不显著正向影响感知趣味性。基于以上分析提出了增加用户持续使用意愿的相关建议。

During the epidemic period of COVID-19，the online fitness service as an important part of“intelligent anti-epidemic” has been widely concerned by the industry and academia.In order to further explore the influencing factors of the continued use willingness of online fitness services，this study integrated the technology acceptance model（TAM）and task-technology fit （TTF），and made an empirical analysis on the influencing factors of users’continuous use of online fitness service by means of network investigation and mathematical statistics.The results show that：（1）the internal and external factors that affect the users’ intention to continue using mainly include 6 items：perceived usefulness，perceived ease of use，perceived interest，task characteristics，technical characteristics and task-technology fit；（2） perceived usefulness，perceived ease of use，perceived interestingness and task-technology fit had significant positive effects on users’intention to use；（3）task characteristics and technical characteristics had significant positive effects on task-technology fit，perceived ease of use significantly positively affected perceived usefulness，while perceived ease of use did not significantly positively affect perceived interestingness.Finally， based on the above results，this study put forward some suggestions to increase users’willingness to continue using.
