The goal of this clinical trial is to learn if transcutaneous electrical nerve stimulation can affect blood flow in healthy volunteers. The main question it aims to answer is: Determine the stimulation parameters (frequency in the range 5- 100Hz and proximal or distal placement) inducing the most significant hyperaemic response in volunteers. Participants will attend to one visit ( 1h30) , 6 protocol of stimulation will be tested on his arm . If his agree, an optionnal measure will be made during another visit. During this optionnal visit, two modalities of intensity adjustment will be tested in regard of the result of the first part of the study.

stimulation parameters that induce the most significant hyperaemic response
Determine the stimulation parameters (frequency in the range 5- 100Hz and proximal or distal placement) that induce the most significant hyperaemic response in volunteers.
Time frame: from enrollment to the end of the procedure (1h30)
Assess the score on a scale of disconfort level during stimulation for each condition
The outcome will be assess using a visual analogic disconfort scale ranging from 0 (no disconfort) to 10 (the highest disconfort imaginable).
Time frame: during testing procedure
Compare stimulation intensities between each condition
Time frame: during testing procedure
Compare muscle metabolic demand between each condition
Time frame: during testing procedure
