Precision in Energy Expenditure: Validating and Refining Resting Metabolic Rate Equations for Collegiate Male Wrestlers

Highlight

• The study cross-validated existing RMR prediction equations using indirect calorimetry in 173 male collegiate wrestlers.
• Body mass-based equations generally underestimated measured RMR; equations incorporating fat-free mass (FFM) showed better accuracy.
• Newly developed prediction equations demonstrated mean bias less than 2% relative to measured RMR, suggesting higher precision.
• Findings support tailored RMR estimation for male wrestlers to optimize nutritional and performance interventions.
