Data_Sheet_3_Communication Mechanism and Optimization Strategies of Short Fitness-Based Videos on TikTok During COVID-19 Epidemic Period in China.PDF

Scientific and moderate exercise is an effective remedy to boost the immune system and minimize the risk of infection in coronavirus disease 2019 (COVID-19) epidemic period. In this context, social media platforms play an essential role in communicating scientific fitness at home. Based on the integrated analysis of communication, physical geography, and health geography, this article takes short fitness-based videos on TikTok as the research object and comprehensively uses text analysis, mathematical statistics, and spatial analysis to reveal the characteristics of communication elements, fitness preferences, and the spatiotemporal evolution of these short videos, and to explore the communication mechanism and optimization path of short videos. The results show that: (1) the communication information focusing on “fighting against the epidemic and keeping fit at home” is made into short videos by female youth. Through the communication channels mainly composed of texts, pictures, and audio, the communication subjects carry out multilevel interactive communication with the communication objects; (2) fitness preferences are mainly composed of dances, unarmed fitness, and fitness with equipment; (3) from the perspective of time, taking February 20 as the node, the daily number of released short videos shows a trend of “increase before decrease”; from the perspective of space, the distribution is significantly unbalanced across provinces, and the direction is not apparent; and (4) this article explores the communication mechanism and targeted optimization countermeasures of short fitness-based videos on TikTok in China's COVID-19 epidemic period.

科学适度的运动是新型冠状病毒肺炎（Coronavirus Disease 2019, COVID-19）疫情期间增强免疫系统、降低感染风险的有效手段。在此背景下，社交媒体平台在居家科学健身的信息传播中发挥着至关重要的作用。本文结合传播学、自然地理学与健康地理学的整合分析框架，以TikTok平台上的健身短视频为研究对象，综合运用文本分析、数理统计与空间分析方法，揭示此类短视频的传播要素特征、健身偏好及时空演化规律，并探讨其传播机制与优化路径。研究结果显示：（1）以“抗疫居家健身”为主题的传播内容多由青年女性制作发布；传播主体以文字、图片、音频为主要传播渠道，与传播客体开展多层次互动传播；（2）用户健身偏好主要涵盖舞蹈、无器械健身与器械健身三类；（3）时间维度上，以2月20日为节点，短视频日均发布量呈现“先升后降”的趋势；空间维度上，各省域分布显著失衡，且集聚方向并不明显；（4）本文探讨了中国COVID-19疫情期间TikTok平台健身短视频的传播机制与针对性优化对策。
