Probiotic Sport Study

April 9, 2013 updated by: Lamprecht Manfred PhD, PhD, Green Beat

Impact of Supplementation With Probiotics on Exercise-induced Oxidative Stress and Endotoxemia in Trained Men

We investigate the impact of a probiotic-based dietary supplement on oxidative stress and endotoxemia before and after strenuous exercise.

Hypotheses (H1):

  • Supplementation has an influence on oxidative stress parameters before and post exercise
  • Supplementation has an influence on parameters of endotoxemia and inflammation before and post exercise
  • Strenuous exercise has an influence on parameters of oxidative stress, inflammation and endotoxemia
