Capillarisation and oxidative capacity constrain muscle fibre size

Data from a study assessing the cross-sectional area, oxidative capacity, and capillary supply of individual muscle fibres from mice, recreationally active humans, and highly resistance-trained men. The dataset, 1.8 MB in size, was authored by Hans Degens and last updated on 2026-05-28. It is shared under a CC-BY-4.0 license on figshare.

Use Cases

• Modeling the relationship between fibre cross-sectional area and oxidative capacity based on the described upper limits.
• Analyzing capillary-to-fibre ratios to understand diffusion constraints in muscle tissue.
• Comparing muscle fibre characteristics across different species (mice, humans) and training statuses mentioned in the study.

Strengths

• Data spans multiple species (mice, humans) and training levels, providing comparative insights.
• The study explicitly tests for upper limits in oxidative capacity and capillary supply per fibre area.
• Dataset is 1.8 MB, making it a manageable size for analysis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
