Brief summary
The aim of the present study is to investigate changes in inflammatory status and incidence of infection after extreme aerobic physical stress (participation in a marathon). In addition, the impact of marathon running on the hemostasis and muscular state will be evaluated. Changes at the inflammatory, muscular, and rheological level will be related to ingestion of oral hydrolytic enzymes and bioflavonoids.
Detailed description
The influence of extreme physical stress, such as that experienced during marathon competition, on the inflammatory system and coagulation has been investigated. However, up until now, countermeasures against these adverse effects are not adequately identified. Immune-modulators (e.g. flavonoids) are known to be present in fruits and vegetables. There are also several different proteolytic and hydrolytic enzymes found in fruits most of whom are attributed protective properties. Therefore, 160 trained and untrained runners will consume a mixture of different enzymes and flavonoids (Wobenzym Plus®) or PL 1 (placebo) and effects on changes in inflammation and hemostasiologic parameters will be investigated during and after extreme physical stress (participation in a marathon race). The clinical result of the perturbation of the immune system will be assessed by the Wisconsin Upper Respiratory Symptom Survey (WURSS-24) with regard to symptoms of the upper respiratory tract system. It is hypothesized that the intake of a product with immunomodulatory potential (Wobenzym Plus ®, consisting of hydrolytic enzymes and flavonoids) can positively influence both inflammation and blood coagulation pertubations observed after a marathon race.
