Methodology
Meta-analysis of randomized trials of inorganic nitrate supplementation measuring steady-state oxygen consumption during submaximal exercise.
Key Findings
Nitrate significantly reduced the oxygen cost of submaximal exercise in untrained and recreationally active participants but not in elite athletes.
Conclusions
Nitrate improves oxygen utilization efficiency mainly in non-elite populations.
Limitations
Small crossover trials; heterogeneous exercise protocols.
Supplements Studied
Nitrate significantly reduced the oxygen cost of submaximal exercise in non-elite participants
Outcomes Measured
Nitrate significantly reduced the oxygen cost of submaximal exercise in untrained and recreationally active participants but not in elite athletes
