Injury Trends in a Japanese Collegiate American Football League, 2018-2024

Yasuyuki Umezaki's dataset on figshare contains injury surveillance data from the Tohoku Collegiate American Football League in Japan. It includes baseline injury data from 2018 to 2023 and official injury reports from the 2024 season following a data-feedback workshop intervention. The 10.0 MB XLSX file was last updated on April 30, 2026.

Use Cases

• Analyze changes in injury proportions (e.g., muscle cramps vs. head injuries) before and after a workshop intervention based on the described ecological analysis.
• Study the association between data-driven feedback and self-reported safety awareness based on the pre- and post-intervention questionnaires mentioned.
• Evaluate the feasibility of injury surveillance programs in resource-limited sports organizations based on the described methodology and findings.

Strengths

• Dataset includes injury data spanning six years (2018-2023 baseline plus the 2024 season).
• The study design is described as a mixed-methods approach combining a cross-sectional survey and a pre-post ecological analysis.
• Specific statistical results are reported, such as an Incidence Rate Ratio of 1.22 for overall injury rate and p-values for changes in injury proportions.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The study authors note limitations including the absence of a control group and a small post-intervention sample size.
