Injury Prevalence in Brazilian Jiu-Jitsu Athletes by Competitive Level

A study of 108 Brazilian jiu-jitsu athletes, separated into novice (n=55) and advanced (n=53) groups, investigated injury types, locations, mechanisms, and severity. The research, authored by Jorge Nelson da Silva, used a questionnaire and statistical analysis to compare injury prevalence between the two competitive levels. The main findings showed shoulders and knees were the most common injury sites, with injury occurrence differing between training sessions and competitions.

Use Cases

• Compare injury prevalence between novice and advanced athletes based on the described group sizes and statistical results.
• Analyze the association between injury location (e.g., major joints) and competitive level based on the reported chi-square and odds ratio findings.
• Model the risk of injury during training versus competition based on the described mechanisms (overuse vs. competition consequence).

Strengths

• Includes data from 108 athletes, providing a defined sample size for analysis.
• Compares two distinct groups (53 advanced and 55 novice athletes) for controlled comparison.
• Reports specific statistical results, including odds ratios indicating a 70-87% lower injury risk for novices in major joints.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Data may reflect bias inherent to the specific study population and methodology described in the paper.
