Exercise Stress Test

Exercise Stress Test

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Background:

Aerobic exercise is known to improve cognitive function, but direct neural evidence is limited.
Electroencephalogram (EEG) microstate analysis offers insights into brain dynamics and mental workload (MWL).

Purpose of the Study:

To investigate how aerobic exercise modulates neural activity during cognitive tasks using EEG microstate analysis.
To examine the effects of exercise on brain microstate parameters under varying mental workload levels.

Main Methods:

Participants performed N-back tasks (1-back and 3-back) under aerobic exercise (ES) and rest (RS) conditions.
EEG data were analyzed for microstate parameters (Occurrences, Time Coverage, Mean Duration) and transition characteristics.

Main Results:

High mental workload increased Mean Duration of microstate class C and decreased Occurrences of class D.
Aerobic exercise improved subjective perception of MWL and increased Time Coverage and Mean Duration of microstate class D.

Conclusions:

Aerobic exercise may enhance cognitive-related microstate dynamics, potentially mitigating mental workload.
Findings suggest exercise influences neural mechanisms associated with cognitive control and parietal-frontal activity.
