- Primary Outcome Measures
Name Time Method The 60-second sprint-test is an all-out test and is performed in a stationary setting. Participants wear a belt around their waist, which is attached to a static rope with an included force transducer. The rope is fixed at a strong anchor point. To assess anaerobic performance, subjects sprint against the resistance at maximal speed (maximal step frequency). Blood gas analyses are carried out using capillary blood samples (100µl) before entering the hypoxic chamber and before and after the sprint-test. In order to assess blood lactate values, capillary blood samples are collected pre-exercise and 2, 5, 7 and 10 minutes after sprinting. Additionally, heart rate is controlled before and directly after the sprint-test.
- Secondary Outcome Measures
Name Time Method utrition protocols (the Freiburger Ernaehrungsprotokoll in German language is used) are completed for each day of the diet. Urinary pH values is determined daily during the experimental trial in spontaneous early morning urine samples.
