About

Introduction and Background:

Transcranial direct current stimulation (tDCS) has emerged as a potential intervention to improve physical performance. The primary aim of this study is to investigate the effects of tDCS applied to the primary motor cortex (M1) and dorsolateral prefrontal cortex (DLPFC) on performance in a maximal effort task, specifically the No Jump Burpee exercise.

Study Design:

This study will utilize a double-blind crossover design, where each subject will complete three experimental conditions: a-DLPFC, a-M1, and SHAM.

Participants:

Twenty healthy male subjects will be recruited for the study.

Intervention:

Each participant will undergo three conditions in a randomized order:

a-DLPFC: tDCS applied to the dorsolateral prefrontal cortex.

a-M1: tDCS applied to the primary motor cortex. SHAM: Placebo stimulation.

Procedure:

Prior to performing the No Jump Burpee exercise to exhaustion, tDCS will be administered at a current of 2 milliampere (mA) for 20 minutes.

Measurements:

The following variables will be measured during the exercise:

Total number of repetitions of the No Jump Burpee exercise. Vastus lateralis muscle oxygen saturation. Heart rate. Subjective perception of exertion (RPE).

Data Analysis:

Repeated measures ANOVAs will be used to analyze the effects of the different tDCS conditions on the performance outcomes.

Ethical Considerations:

The study protocol will be reviewed and approved by an appropriate ethics committee. Written informed consent will be obtained from all participants before participation in the study.

Objectives:

The primary objective is to evaluate the impact of tDCS on physical performance, specifically measuring the total number of repetitions of the No Jump Burpee exercise. Secondary objectives include assessing the changes in muscle oxygen saturation, heart rate, and subjective perception of exertion.

20 participants in 3 patient groups

tDCS Targeting the Dorsolateral Prefrontal Cortex (DLPFC)
Experimental group
Description:
Participants in this arm will receive transcranial Direct Current Stimulation (tDCS) targeting the DLPFC. The tDCS will be administered at an intensity of 2 mA for 20 minutes. This arm aims to evaluate the effects of DLPFC stimulation on performance during a maximal effort "No Jump Burpee" exercise.
Treatment:
Device: tDCS targeting DLPFC
tDCS Targeting the Primary Motor Cortex (M1)
Experimental group
Description:
Participants in this arm will receive transcranial Direct Current Stimulation (tDCS) targeting the primary motor cortex (M1). The tDCS will be administered at an intensity of 2 mA for 20 minutes. This arm aims to evaluate the effects of M1 stimulation on performance during a maximal effort "No Jump Burpee" exercise.
Treatment:
Device: tDCS targeting M1
SHAM tDCS
Sham Comparator group
Description:
Participants in this arm will receive a sham tDCS session, which simulates the experience of tDCS without actual stimulation. This arm serves as a control to ensure the blinding of participants and evaluators.
Treatment:
Device: SHAM tDCS
