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

The Tohoku Collegiate American Football League in Japan is the focus of this mixed-methods study on injury epidemiology. It contains injury surveillance data from 2018 to 2023 as a baseline, with official injury reports from the 2024 season following a data-feedback workshop. The dataset was authored by Yasuyuki Umezaki and last updated on 2026-04-30.

Use Cases

• Analyzing trends in injury rates and types based on the described pre-post ecological analysis.
• Evaluating the impact of data-feedback interventions on safety awareness based on the described questionnaire results.
• Studying shifts in injury proportions, such as muscle cramps and head injuries, as described in the pre-post comparison.

Strengths

• Data covers a six-year period from 2018 to 2024, providing a longitudinal baseline.
• Includes specific statistical results, such as an Incidence Rate Ratio of 1.22 for overall injury rate and p-values for changes in injury proportions.
• Released under a permissive CC-BY-4.0 license, allowing for reuse and modification.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The study design is described as non-randomized and uncontrolled with a small post-intervention sample size, which may limit generalizability.
