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. Yasuyuki Umezaki published the dataset on figshare in 2026, which includes injury data from 2018 to 2023 as a baseline and official reports from the 2024 season following a data-feedback workshop.

Use Cases

• Analyze changes in injury rates and types based on pre- and post-intervention data mentioned in the description
• Study the impact of data-feedback workshops on safety awareness among team representatives as described
• Compare proportions of specific injuries like muscle cramps and head injuries before and after an intervention
• Conduct ecological analyses of injury trends in a specific regional sports league over a multi-year period

Strengths

• Injury data spans a 6-year baseline period from 2018 to 2023
• Includes pre- and post-intervention questionnaire results on participant perceptions
• Reports specific injury proportion changes with statistical significance values (e.g., muscle cramps decreased from 37.2% to 7.7%)

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
