简要总结
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.

盲法说明
To ensure a double-blind design, the researcher who administered the tDCS was not present during the physical measurements, and the evaluator responsible for the physical measurements was unaware of the type of tDCS received by the participant. In this way, participants and evaluators remained blinded to the treatment administered.

结局指标
主要结局
Number of "No Jump Burpees" to Exhaustion
时间窗: Measured immediately at the end of each experimental session (DLPFC, M1, SHAM), approximately 5-10 minutes after the start of the test..
The primary objective of the study is to measure the number of repetitions of the "No Jump Burpee" exercise that participants can perform until exhaustion. This exercise is performed at a cadence of 20 burpees per minute, and exhaustion is determined when the participant can no longer maintain the correct pace or technique.
次要结局
- Muscle Oxygen Saturation in the Vastus Lateralis(Measured continuously at a frequency of 1 Hz during the exercise, from the start until the participant reaches exhaustion, approximately 5-15 minutes per session.)
- Heart Rate During Exercise(Measured continuously on a beat-by-beat basis during the exercise, from the start until the participant reaches exhaustion, approximately 5-15 minutes per session.)
- Rating of Perceived Exertion (RPE)(Measured every 20 seconds during exercise, from the start until the participant reaches exhaustion, approximately 5-15 minutes per session.)
