摘要

Background

The rise in youth karate competition participation correlates with elevated injury risk. This study investigated injury incidence and patterns among Iranian junior athletes at the 2023 National Karate Championships (Tehran, April–May 2023), the official selection event for the national team, considering differences by age, sex, weight, and bout characteristics.

Methods

A prospective cohort design was employed, analyzing data from 1391 athletes across 1544 bouts. Injury data were systematically collected by qualified medical personnel using standardized forms. Injury incidence rates (IIRs) were rigorously calculated per 1000 athlete-exposures (AEs) and per 1000 min of exposure (MEs) to account for varying exposure durations.

Results

A total of 527 injuries were recorded during the competition. The overall IIR was determined to be 18.94 per 1000 AEs and 9.02 per 1000 MEs. The face was identified as the most commonly injured anatomical site, accounting for 46% of all injuries, while contusions were the most frequent injury type, comprising 48%. Athletes in the Under-21 (U21) male category exhibited the highest injury rates. Furthermore, more than half (52%) of all recorded injuries occurred within the first minute of a bout, and losing athletes sustained a disproportionately high 59% of the total injuries.

Conclusion

In conclusion, this study identified a high injury incidence among Iranian junior karate athletes, with the face being the most commonly affected region and contusions the predominant injury type. Male and U21 athletes showed notably higher injury rates, particularly early in bouts and among those who lost. These findings highlight the need for targeted preventive strategies and serve as a national benchmark for future injury surveillance in youth karate.
