Clinical Trial Summary

Relatively high level athletes will undergo 2 randomized, cross-over counterbalanced sessions of bi-anodal tDCS (transcranial direct current stimulation) or sham tDCS The primary outcome is a 3D evaluation coupled with EMG (Electromyography) of their primary lower limb muscles after each session

Description:

Recruitment :

Relatively high level athletes will be recruited through social media and advertisements.

Each subject came twice to the Liege University Hospitals' Human Movement Analysis Laboratory.

After placing the different infrared emitters and placing and calibrating the surface EMG electrodes, subjects underwent 3 maximal squat jumps (without upper limb implication). They were then familiarized with the fatigue protocol (8 jumps at a 33 jumps per minute pace).

Then each subject received either bi-anodal tDCS of sham tDCS. Neither the evaluator or the subject knew which they were receiving. Immediately following tDCS, subjects underwent another warmup 3 maximal squat jumps, and then the fatigue protocol (comprised of 30 maximal jumps at a rate of 33 per minute).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Peak Height	Peak height (measured by the 3D device) is measured after each of the 30 repetitions as well as after the 3 jumps before and after tDCS. Height decrease will also be looked at	Changes between Prior and Immediately Following tDCS and Sham
Primary	Gluteal EMG (Electromyography) recordings (% of maximal EMG value)	Bilateral Gluteal EMG	Changes between Prior and Immediately Following tDCS and Sham
Primary	Quadriceps EMG (Electromyography) recordings (% of maximal EMG value)	Bilateral Quadriceps EMG triceps surae will be measured	Changes between Prior and Immediately Following tDCS and Sham
Primary	Triceps EMG (Electromyography) recordings (% of maximal EMG value)	Bilateral Triceps Surae EMG	Changes between Prior and Immediately Following tDCS and Sham
