About this study

Official title: The Effect of Anodal Transcranial Direct Current Stimulation Combined With Aerobic Exercise on Performance in Healthy Individuals

The purpose of this study is to assess the effects on the exercise performance of anodal transcranial direct current stimulation combined with aerobic exercise in healthy individuals.

Read the detailed description

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Real tDCSDevice

    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.

  • Sham tDCSDevice

    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.

  • ExerciseOther

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Effect of tDCS combined with aerobic exercise on exercise performance in healthy individuals.

    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

    Measured: 2 months

  2. Effect of tDCS combined with aerobic exercise on ratings of perceived exertion (RPE) in healthy individuals.

    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").

    Measured: 2 months

Secondary outcomes (1)
  1. Effect of tDCS combined with aerobic exercise on isokinetic muscle strength in healthy individuals.

    The isokinetic muscle strength of knee extensors of the dominant leg will be evaluated by using Biodex System 3 isokinetic dynamometer (Biodex Medical Systems, Shirley, NY, USA)

    Measured: 2 months

Questions about this trial

What is this clinical trial studying?

A study testing Real tDCS and Exercise in people with Healthy, run by Marmara University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 27 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

How can a doctor refer a patient or contact the research team?

Contact Bahar Ayberk, MSc (00902164140545, bahar.ayberk@marmara.edu.tr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Effect of tDCS combined with aerobic exercise on exercise performance in healthy individuals. (time frame: 2 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
