3D Analysis of the Effects of tDCS (Transcranial Direct Current Stimulation) on a Functional Task in High Level Athletes

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

About this study

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).

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • At least 10 hours of sport a week
  • Right handed and footed

Exclusion criteria

  • One on the TSST (in high and relatively high risk sections)
  • Previous neurological or orthopedic pathologies affecting limbs

Treatment and study plan

tDCS

Device

20 minutes of anodal tDCS (C3 & C4/FPZ) 2mA or sham

Other names: Non invasive brain stimulation

Primary outcomes

  1. Peak Height

    Time frame: 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

  2. Gluteal EMG (Electromyography) recordings (% of maximal EMG value)

    Time frame: Changes between Prior and Immediately Following tDCS and Sham

    Bilateral Gluteal EMG

  3. Quadriceps EMG (Electromyography) recordings (% of maximal EMG value)

    Time frame: Changes between Prior and Immediately Following tDCS and Sham

    Bilateral Quadriceps EMG triceps surae will be measured

  4. Triceps EMG (Electromyography) recordings (% of maximal EMG value)

    Time frame: Changes between Prior and Immediately Following tDCS and Sham

    Bilateral Triceps Surae EMG
