Supplementary Data for Joyner's Endurance Model Analysis in 888 Athletes

Supplementary files for a study analyzing Joyner's endurance performance model in 888 recreational to world-class athletes. The data includes physiological test results for 495 runners and 393 cyclists, measuring VO2max, lactate thresholds, and exercise economy. The files were authored by Lois Mougin and last updated on June 2, 2026.

Use Cases

• Modeling the relationship between VO2max and speed/power at lactate threshold based on the study's regression analysis.
• Analyzing the relative contribution of exercise economy to endurance performance proxies as described in the results.
• Comparing physiological determinants like fractional utilization at lactate threshold between runners and cyclists using the cohort data.
• Validating performance prediction models against the reported strong agreement (R²=0.94-0.99) between estimated and measured proxies.

Strengths

• Dataset is associated with a specific, detailed study published on figshare, providing clear methodological context.
• Includes data from 888 individuals, a sample size that allows for analysis across a performance spectrum from recreational to world-class.
• Reports specific physiological averages (e.g., runners' VO2max: 56 mL/kg/min, cyclists' economy: 14.7 mL/min/W), indicating quantified measurements.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (810.3 KB), suggesting limited scope, likely containing summary statistics or supplementary tables rather than raw individual records.
