Brief Summary:
The aim of the study is to present the quantitative differences in oxygenated hemoglobin in different cohorts.
This clinical study evaluates whether there is a correlation between measurements using multispectral optoacoustic tomography and the results of spiroergometry in the context of performance diagnostics.

Detailed Description:
This study aims to investigate the muscle metabolism of athletes (endurance and strength athletes), PAD patients, and healthy control subjects using non-invasive multispectral optoacoustic tomography as part of interval treadmill spiroergometry. The aim is to take a closer look at changes in oxygen supply and muscle metabolism in the various patient groups during the recovery phase. To this end, the individual groups will perform a performance diagnosis on a treadmill spiroergometer, adapted to their respective estimated physical performance (in the case of PAD patients, taking into account the possibilities given by the disease), which will be carried out in the form of a step test. In addition, MSOT measurements will be taken between the individual steps.
The aim of this study is to use MSOT to visualize and compare the muscle perfusion-in particular the proportion of oxygenated and deoxygenated hemoglobin (Hb)-of the various cohorts, as well as to compare it with the diagnostics and methods commonly used to date and identify any advantages. In the future, this could contribute to a better understanding of muscle perfusion, especially in connection with diseases such as PAD or other muscle lesions in sports medicine.
