Dietary Supplementation on Physical Performance and Recovery in Active-Duty Military Personnel: A Systematic Review of Randomized and Quasi-Experimental Controlled Trials
Nutrients (2024) · Systematic review
Nutrition supplementation may have small benefits on muscle performance and recovery in warfighters.
Based on meta-analyses showing 5-15% strength increases. Upper-body improvements 4.43kg, lower-body 11.35kg. Effects plateau at therapeutic doses.
Meta-analyses show small but significant effects on total body mass and fat-free mass. Effect sizes are consistently reported as 'small' (ES ~0.21-0.22). Multiple studies show no significant effects in older adults or sarcopenia patients. HMB-FA form may have superior bioavailability to HMB-Ca.
