Primary Outcome Measures

Name	Time	Method
As a surrogate marker for the improvement of fat oxidation in the endurance performance, the 1-hour time course (1h-TT) is determined.

Secondary Outcome Measures

Name	Time	Method
The velocity at the aerobic threshold (VLT), individual anaerobic threshold (VIAT) as well as the change in fat mass (FM) are defined as the secondary output.
