ClinicalTrials.gov Identifier:
NCT01821820
First received: March 27, 2013
Last updated: January 30, 2015
Last verified: January 2015
  Purpose

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.

Further study details as provided by Appalachian State University:

Primary Outcome Measures:
  • Shifts in metabolites (metabolomics) [ Time Frame: 14-day period ] [ Designated as safety issue: No ]
    Shifts in metabolites pre-and post-14-days supplementation, and then after 75-km cycling, and the next morning.


Secondary Outcome Measures:
  • Inflammation [ Time Frame: 14-day period ] [ Designated as safety issue: No ]
    Pre- and post-14 d supplementation, and following 75-km cycling; plasma IL-6, IL-8, IL-10, TNF-alpha, G-CSF, MCP-1; C-reactive protein

  • Immune Function [ Time Frame: 14-day period ] [ Designated as safety issue: No ]
    Pre- and post-14 days supplementation, and following 75-km cycling; granulocyte and monocyte phagocytosis and oxidative burst activity; leukoycte differential

  • Oxidative Stress [ Time Frame: 14-day period ] [ Designated as safety issue: No ]
    Pre- and post-14 days supplementation, and following 75-km cycling; RBC glutathione, protein carbonyls, ORAC, FRAP, F2-isoprostanes
