Supplementary Files for Running Economy Reliability Study in Endurance Runners

Supplementary PDF files for a study assessing the test-retest reliability of running economy and other physiological parameters during a 90-minute run. The study involved 14 well-trained male marathon runners with a maximal oxygen uptake of 63.1 ± 5.8 mL·kg⁻¹·min⁻¹. The files, authored by Michele Zanini and last updated in April 2026, accompany the published research article.

Use Cases

• Assessing the reliability of running economy durability measurements based on energy and oxygen cost data.
• Analyzing physiological parameter variability during prolonged exercise based on ventilation, heart rate, and blood lactate measurements.
• Designing future experiments on endurance athlete durability based on the provided reliability statistics (ICCs, CV, TE).

Strengths

• Data is directly linked to a peer-reviewed study with a specific sample of 14 well-trained male runners.
• Reliability is quantified using multiple statistical measures (ICCs, CV, TE) for key parameters.
• Published under a permissive CC-BY 4.0 license.

Limitations

• The dataset consists of supplementary PDF files; the underlying raw data is not directly provided.
• Row count and column-level documentation are unknown, limiting suitability assessment.
• The sample is limited to well-trained male marathon runners, which may affect generalizability.
