Detaljeret beskrivelse

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation method that has become increasingly popular in recent years. tDCS shows promising improvements for the motor performance of healthy individuals as well as pathological conditions. Moreover, it is frequently preferred because of its safety advantage, high tolerability as well as being cheap, portable and easily applicable.

Studies have shown that tDCS can modulate the excitability of both cortical and subcortical brain regions. In recent years, there have been scientific studies investigating the effects of tDCS on improving physical performance in healthy individuals, but these studies are limited in number, their results are conflicted and as far as the investigators know there is no study that combines tDCS with exercise.

Moreover, although the mechanisms of tDCS on physical performance are largely unknown, some tDCS devices are open to public usage and a large number of professional athletes have reported using tDCS during their training programs. Therefore, studies are needed to demonstrate the effects of tDCS which combined with exercise on performance.

The aim of this study was to investigate the effects of anodal transcranial direct current stimulation combined with aerobic exercise on physical performance in healthy individuals.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Real tDCS and Exercise
tDCS (tDCS - TCT Research Limited, Hong Kong) / Exercise Group in which will receive the active intervention of aerobic exercise training and active tDCS intervention at the same time.
Enhed: Real tDCS
Real tDCS (TCT Research Limited, Hong Kong); 3 times a week on alternate days for consecutive 6 weeks. The active session of tDCS will consist in applying anodal stimulation over left M1 (C3 according to the 10-20 international EEG placement) and the cathodal stimulation over right supraorbital area (Fp2 according to the 10-20 international EEG placement), and to inject 2 mA for 20 minutes through sponge electrodes (35 cm²) placed on the scalp.
Andet: Exercise
The Exercise intervention will include only aerobic exercise 3 times a week on alternate days for consecutive 6 weeks. The program will last 20 minutes.
Sham-komparator: Sham tDCS and Exercise
Sham tDCS (tDCS - TCT Research Limited, Hong Kong) / Exercise Group in which will receive the active intervention of aerobic exercise training and sham tDCS intervention at the same time.
Andet: Exercise
The Exercise intervention will include only aerobic exercise 3 times a week on alternate days for consecutive 6 weeks. The program will last 20 minutes.
Enhed: Sham tDCS
Sham current (TCT Research Limited, Hong Kong); 3 times a week on alternate days for consecutive 6 weeks. The sham tDCS will use the same montage and device but direct current will only be injected for 30 seconds, with a ramp-up and ramp-down 15 seconds period, to mimic the somatosensory effects of active tDCS.
Andet: Exercise
Exercise group in which will receive the active intervention of aerobic exercise training no tDCS intervention.
Andet: Exercise
The Exercise intervention will include only aerobic exercise 3 times a week on alternate days for consecutive 6 weeks. The program will last 20 minutes.

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Effect of tDCS combined with aerobic exercise on exercise performance in healthy individuals.
Tidsramme: 2 months
The performance will be evaluated by measuring the maximal consumption of oxygen (VO2max). VO2max will be assessed continuously during the time to exhaustion trial using a gas analyzer
2 months
Effect of tDCS combined with aerobic exercise on ratings of perceived exertion (RPE) in healthy individuals.
Tidsramme: 2 months
RPE will be assessed continuously (every 3 minutes) during the time to exhaustion trial using the Borg rating of perceived exertion scale (RPE scale). The Borg RPE scale is a quantitative measure of perceived exertion during physical activity. The scale starts with "no feeling of exertion," which rates a 6, and ends with "very, very hard," which rates a 20. Moderate activities register 11 to 14 on the Borg scale ("fairly light" to "somewhat hard"), while vigorous activities usually rate a 15 or higher ("hard" to "very, very hard").
