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

2018 to 2024 injury surveillance data from the Tohoku Collegiate American Football League in Japan, used to study the impact of a data-feedback workshop. The dataset was created by Yasuyuki Umezaki and includes pre- and post-intervention questionnaire responses and official injury reports from a single 2024 season. It was last updated on 2026-04-30.

Use Cases

• Analyze changes in injury type proportions (e.g., muscle cramps vs. head injuries) based on the pre-post ecological analysis described.
• Study the relationship between safety awareness and injury reporting based on the self-reported questionnaire data mentioned.
• Evaluate the practical application of injury surveillance feedback for resource-limited sports organizations based on the study's stated aim.

Strengths

• Data spans six years from 2018 to 2023 as a baseline, plus the 2024 season for post-intervention analysis.
• Includes specific statistical results, such as an Incidence Rate Ratio of 1.22 for overall injury rate and p-values for proportional changes in injury types.
• Released under a permissive CC-BY-4.0 license, facilitating reuse and sharing.

Limitations

• The study design was non-randomized and uncontrolled, limiting causal inference as noted in the description.
• The post-intervention sample size is described as small, which may affect the statistical power of the findings.
• Column-level documentation is absent; field semantics must be inferred after download.
