About this trial
This is an interventional basic science trial for Oxidative Stress focused on measuring oxidative stress, inflammation, endotoxemia, strenuous exercise
Eligibility Criteria
Inclusion Criteria:
- trained men
- 30 - 45 years
- non-smokers
- 4wk wash out of all dietary supplements
Exclusion Criteria:
- untrained people (VO2max < 55 ml x kg-1)
- female
- all people not matching this age group
- smokers
- all men taking dietary supplements
- all men that fail in ergometric exercise eligibility testing, refering to the standards in sports medicine (e.g.: significant ST-decrease or increase, blood pressure > 240 mmHg, tachycardia, polymorphic extrasystolia, cyanosis, bradyarrhythmia..)

5. Study Description
Brief Summary
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
