Abstract
Since the outbreak of the Coronavirus, the health problem has become prominent. Under the impact of community lockdowns caused by the coronavirus, online fitness has become more popular and there are three main reasons. First, online fitness is the synthesis of sports and internet technology and provides a platform to exercise. Second, with the development of 5G technology, online fitness can make use of any place and time of fragmentation to exercise. Third, compared with the traditional model, online fitness has advantages in both type and price. However, due to the weak sense of participation in online fitness, users will inevitably feel lonely, but by sending bullet screens, users have created a new participatory culture. This research selected over 100,000 bullet screens from Bilibili, which is a comprehensive video community with a high concentration of young generations in China. Besides, we also use Python to analyze these bullet screens for content and emotion analysis from the time and content dimensions. The results show that compared with the traditional model, the fitness video can bring more sense of participation and presence, and the impact on people's enthusiasm is positive, which will further prove that participatory culture plays an indispensable role in the effect of community health. In addition, we also find that over time, user engagement in bullet screens with the same video decreases.
