Use of Laser Speckle to Study Cutaneous Blood Flow at Exercise in Healthy Subjects
Evaluation Chez Des Sujets Sains d'Une Nouvelle Technique d'étude de la Microcirculation cutanée
We aim to test the hypothesis that Laser speckle contrast imaging allows for the measurement of cutaneous blood flow during exercise.
Ischemia and post occlusive reactive hyperhemia in the skin is tested in healthy normal subjects at rest and during cycle exercise.
