Judo is a Martial art created in 1882 characterized by a great number of techniques and philosophical basis, and it has been mentioned in several studies as one of the sports presenting a higher amount of injury occurrences. Nevertheless, there are few detailed surveys to allow performing a causal correlation between the technical aspects and the percentage picture of the injuries found in this sportive modality.

The mean time of practice for male athletes was 9 ± 6 years, and their level was distributed as follows: 20% black belt, 50% brown belt, and 30% distributed as follows: 20% black belt, 50% brown belt, and 30% mean time of practice of 5 ± 3 years, distributed as follows: 9% black belt, 25% brown belt, and 66% with lower than brown belt level.
After applying a questionnaire, it was observed that injuries occurred in 23% prevalence in the knee joint, followed by 16% in the shoulder, 22% in fingers and toes, and the remaining occurences amounted 39%. 10% of injuries were mild, 9% were moderate injuries, and 63% were severe injuries.
