Birth Weight and Kidney Function in Ultramarathon Athletes

Alison A. Murray published a study on figshare in April 2026. The dataset likely contains results from an analysis of 44 ultramarathon athletes racing in hot or cold conditions. It examines how birth weight, alongside factors like sex, age, and hydration, predicts changes in serum creatinine, a marker of kidney damage, after prolonged endurance exercise.

Use Cases

• Modeling kidney function response to endurance exercise based on birth weight and hydration status mentioned in the description
• Investigating the U-shaped relationship between birth weight and transient renal damage after prolonged activity
• Analyzing the combined effects of sex, age, distance, and muscle damage on creatinine variance
• Studying the evolutionary constraints on human endurance capacity through renal functional proxies

Strengths

• Dataset includes data from 44 athletes, providing a specific sample size
• Analysis explains ~58% of variance in creatinine change using a model with birth weight terms
• License is CC-BY-4.0, allowing open reuse and modification

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is stored in a DOCX file (670.8 KB), which may require extraction of tabular data
