Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

We aim to test the hypothesis that Laser speckle contrast imaging allows for the measurement of cutaneous blood flow during exercise.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Ischemia and post occlusive reactive hyperhemia in the skin is tested in healthy normal subjects at rest and during cycle exercise.
