ABSTRACT
COVID-19-associated lockdown has been implemented worldwide, potentially causing unfavorable changes in lifestyle and psychological health. Physical literacy, healthy diets, and lifestyles play important roles in mitigating the adverse effects. Therefore, this study aimed to enable individuals to understand their fitness literacy and establish a personalized exercise plan. In this study, 903 adults aged 19－59 were surveyed based on the concept of scientific fitness literacy and the influencing factors in the context of the effective containment of COVID-19 before (2019) and during (2020) the pandemic. This study screened four factors from four dimensions–cognition, attitude, ability and skills, and behavior and habits–that can influence adults' scientific fitness literacy. Confirmatory factor analysis (CFA) and AMOS software were used to construct an evaluation index system of scientific fitness literacy for adults. The model consisting 10 items with 4 factors to evaluation index system has good overall fitness, reliability, convergent validity, differential validity, and model stability and was able to analyze the factors that affect the scientific fitness literacy of individuals from different perspectives. This allowed individuals at different stages to have a deeper understanding of scientific fitness literacy.
