The impact of COVID-19 on the Taekwondo industry using intervention time-series analysis
The purpose of this study was to analyze the impact of COVID-19 on the Taekwondo industry using an intervention time series analysis method based on time series data using intervention time series analysis based on the time series data of Persons who have acquired Taekwondo qualifications for the past 18 years (2006 to 2023). To achieve this research purpose, the Causal Impact package function provided by ‘python’ programming was used for analysis. The results of this study indicated as follows. First, COVID-19 had a negative impact of 41.58% on new members in the Taekwondo industry. Second, COVID-19 had a negative impact of 30.36% on existing members in the Taekwondo industry. Discussions and practical implications were also suggested.
