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

Injury surveillance data from the Tohoku Collegiate American Football League in Japan, covering the 2018 to 2023 baseline period and the 2024 post-intervention season. The dataset was created by Yasuyuki Umezaki and uploaded to figshare in April 2026. It was used in a mixed-methods study exploring the impact of a data-feedback workshop on injury reporting and trends.

Use Cases

• Analyze changes in injury rates and proportions before and after an intervention based on the pre-post ecological analysis described.
• Study the relationship between data feedback and self-reported safety awareness based on the pre- and post-intervention questionnaires mentioned.
• Investigate reporting patterns for specific injury types like muscle cramps and head injuries based on the proportional shifts highlighted in the description.

Strengths

• Data spans a 6-year period from 2018 to 2023 for baseline, plus the 2024 season.
• Includes specific statistical results such as an Incidence Rate Ratio of 1.22 and p-values for injury proportion changes.
• Released under a permissive CC-BY-4.0 license, allowing for broad reuse.

Limitations

• The study design was non-randomized and uncontrolled, limiting causal inference.
• The post-intervention sample size for the 2024 season is described as small.
• Column-level documentation is absent; field semantics must be inferred after download.
