The pandemic of COVID-19 from 2020 to 2021 has various effects on university sports. The purpose of this study was to compare the results of Japanese inter college swimming championships between pre and pandemic of COVID-19, and to clarify the trends of the performance in competition. The racing times of the top 16 swimmers in each event were extracted from the results of Japanese inter college swimming championships from 2018 to 2021 and were compared between the years. If there was a significant difference in the racing times between the years, the inter-years comparison of the lap times was executed as the additional survey. The results indicated that men’s 100 m breaststroke, men’s 200 m breaststroke, and women’s 50 m freestyle in 2021 were significantly improved compared to the years before COVID-19 pandemic (all p < .05). In contrast, it was confirmed that women’s 200 m backstroke in 2021 was significantly lower than that in the year before COVID-19 pandemic (p < .05). From these results, it was clarified that the competition performance of Japanese collegiate swimmers was maintained in COVID-19 pandemic except women’s 200 m backstroke, and that some events improved than the level before COVID-19 pandemic. In addition, it was revealed that the intermediate lap time of women’s 200 m backstroke in 2021 was lower than before the COVID-19 pandemic. Therefore, it was suggested that the improvement of intermediate lap lime is a future task in this event.
