Effects of tDCS on High Level and Recreational Athletes

Not Applicable

Completed

• Conditions: Healthy; Athlete
• Interventions: Device: tDCS

• Registration Number: NCT03893604
• Lead Sponsor: University of Liege

Brief Summary

Healthy recreational and high level athletes will undergo 2 randomized, cross-over counterbalanced sessions of anodal tDCS or sham tDCS.

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

Detailed Description

Recruitment :

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

Each subject came twice 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 received either anodal tDCS, of sham tDCS. Neither the evaluator or the subject knew which they were receiving. Immediately following tDCS, there was a warmup consisting of stationary bike, and an isokinetic warmup. Then, subjects' endurance was using a maximal isokinetic tests, at 30 maximal concentric and eccentric contractions at a speed of 180°/s.

Arm && Interventions

Group	Intervention	Description
Sham tDCS	tDCS	Subjects will receive 20 minutes of Sham anodal tDCS
Anodal tDCS	tDCS	Subjects will receive 20min anodal tDCS

Primary Outcome Measures

Name	Time	Method
Peak Strength	Immediately after tDCS and sham	Peak strength (measured by the isokinetic machine) is measured after each of the 30 repetitions.; Peak strength of the 30 repetitions will be measured, and how strength decreases throughout the test will be analysed
