(Purpose) We analyzed injury reports of team belonging to the university soccer TOP league. (Mate rials) 44 players who were enrolled in the top team in the 2021 season. (Methods) We recorded the exposure time and number of injuries for each player and calculated the injury rate. Injury site, injury type, onset factors, and se verity were investigated by year and month. (Results) The number of injuries was 40, exposure time was 13,543 hours, and injury rate was 2.3/1,000 hours (95% CI: 1.8-3.8). Injury rate changes by month showed the highest in February at 6.4/1,000hours, and the highest in June at 41.3/1,000hours during matches. As a monthly trend, num ber of injuries and injury rate were high in February, June, September and October, and exposure time in the pre vious month tended to be low. As for injury type, sprain/ligament injury occurred most frequently, and muscle rupture occurred less frequently. (Discussion) The injury rate was lower than those of the top leagues in other countries. On the other hand, an increase in the total activity time by month may increase injury rate. Sprain/liga ment injury was the most common type of injury, while muscle rupture was rare, suggesting that it was not af fected by COVID-19.
