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

Yasuyuki Umezaki's 14.0 KB dataset contains injury surveillance data from the Tohoku Collegiate American Football League in Japan. It compares injury rates and types from a 2018-2023 baseline to the single 2024 season following a data-feedback workshop. The mixed-methods study found a proportional decrease in muscle cramps and an increase in reported head injuries post-intervention.

Use Cases

• Analyze the impact of data-feedback workshops on injury reporting trends based on pre-post ecological analysis.
• Study shifts in injury type proportions, such as muscle cramps versus head injuries, following an awareness intervention.
• Evaluate changes in self-reported safety awareness among team representatives based on questionnaire data.
• Assess injury rates per game in a regional collegiate sports league over a multi-year period.

Strengths

• Provides a 6-year temporal coverage from 2018 to 2024 for longitudinal analysis.
• Includes specific statistical results, such as an Incidence Rate Ratio of 1.22 for overall injury rate and p-values for injury proportion shifts.
• Data is associated with a published mixed-methods study comprising survey and ecological analysis.

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 was non-randomized and uncontrolled with a small post-intervention sample size, as noted in the description.
