Brief summary

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

Detailed description

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

Interventions

OTHERtourniquet ischemia

Recording of cutaneous blood flow on the forearm at rest and during cycle exercise 50W before and following tourniquet ischemia
