A Single Session of tDCS (Transcranial Direct Current Stimulation) Improves Endurance for 30 Minutes

A Single Session of a-tDCS Improves Lower Limb Endurance for 30 Minutes in Healthy Subjects

Healthy recreational athletes will undergo a session of anodal tDCS (transcranial direct current stimulation) or sham tDCS.

The primary outcome is an isokinetic evaluation of their hamstrings' and quadriceps' strength before and after each session

Healthy recreational athletes will be recruited through social media and advertisements.

Each subject came to the Liege University Hospitals' isokinetic lab. Each session began with strapping the subjet into the isokinetic machine, making sure that all the settings were adapted to the subject. Then, each subject underwent a concentric and eccentric isokinetic test of their lower limbs (dominant or non-dominant side depending on their group). Subjects then received either anodal tDCS, of sham tDCS. Neither the evaluator or the subject knew which they were receiving. Immediately following tDCS, there was a another isokinetic test, and 30 minutes after the second test, a subjects underwent a third test.
