NCT01821820

Brief Summary

Ingestion of 3 ounces of pistachio nuts per day for two weeks before and the day of cycling intensely for 75 kilometers will support substrate utilization during exercise (as determined through metabolomics) and improve performance compared to water only, and attenuate inflammation, oxidative stress, and immune dysfunction during 24 hours of recovery.
