Heat Stress and Dehydration Effects on Carbohydrate Metabolism in Exercise

A 2024 systematic review and meta-analysis synthesizes findings from 51 studies involving 502 participants, published up to November 2024. The research, conducted by Loïs Mougin, investigates the impact of heat stress and dehydration on carbohydrate oxidation, glycogen use, and respiratory exchange ratio during endurance exercise. Supplementary files include the detailed PRISMA-compliant review methodology and results.

Use Cases

• Analyze the reported standardized mean differences (SMDs) for carbohydrate oxidation and glycogen use between hot and temperate conditions.
• Examine the meta-analysis results for interaction effects between dehydration status and environmental temperature on fuel utilization metrics.
• Review the PRISMA flow diagram and study inclusion/exclusion criteria to understand the systematic review's scope.
• Extract data from the 51 included studies to build a secondary dataset on participant demographics, exercise protocols, and outcome measures.

Strengths

• Based on a systematic review of 51 original studies, providing a synthesized evidence base.
• Includes meta-analysis results with specific statistical outputs like standardized mean differences (SMDs) and p-values.
• Follows PRISMA guidelines, ensuring a structured and transparent review methodology.

Limitations

• The dataset is a 1.7 MB PDF, limiting direct computational analysis without manual or automated data extraction.
• The underlying participant count (502) is aggregated from multiple studies, preventing individual-level analysis.
• Temporal coverage is limited to studies published up to November 2024, and may not include the most recent research.
