简要总结
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
详细描述
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).

结局指标
主要结局
Peak Height
时间窗: Changes between Prior and Immediately Following tDCS and Sham
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
Gluteal EMG (Electromyography) recordings (% of maximal EMG value)
时间窗: Changes between Prior and Immediately Following tDCS and Sham
Bilateral Gluteal EMG
Quadriceps EMG (Electromyography) recordings (% of maximal EMG value)
时间窗: Changes between Prior and Immediately Following tDCS and Sham
Bilateral Quadriceps EMG triceps surae will be measured
Triceps EMG (Electromyography) recordings (% of maximal EMG value)
时间窗: Changes between Prior and Immediately Following tDCS and Sham
Bilateral Triceps Surae EMG
