|Active Comparator: polyphenols (non-alcoholic beer)||
Dietary Supplement: polyphenols (non-alcoholic beer)
1.0 - 1.5 l non-alcoholic beer per day; 3 weeks before and during a marathon run

Dietary Supplement: beverage without polyphenols
1.0 - 1.5 l of beverage without polyphenols (otherwise the same composition as non-alcoholic beer) per day; 3 weeks before and during a marathon run
Regular exercise leads to an improvement of cardiovascular risk factors in patients with coronary heart disease, atherosclerosis and metabolic disorders.
Aerobic exercise has anti-inflammatory effects. In contrast, the exertional exercise of marathon running causes an acute pro-inflammatory impulse. This may lead to myocardial injury and, in case of preexisting plaques, may result in plaque rupture and acute myocardial infarction.
We aim to define the critical role of inflammatory markers and cardiovascular risc factors as a predictor of an increased risk for myocardial and endothelial dysfunction in marathon runners.
Diagnostic tools include measurements of microvasculature, the large vessels and echocardiography. Inflammatory markers include high sensitive c-reactive protein (CRP) and interleukins.
All variations are analysed on the basis of consumption of polyphenols as they are found in in hops (Humulus lupus L.) and beer.
