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:

Accurate mental workload assessment is critical for safety-sensitive occupations.
Existing models often neglect the impact of physical activity on cognitive load.
Real-world scenarios for first responders involve dynamic physical exertion.

Purpose of the Study:

To introduce the WAUC multimodal database for mental workload assessment under physical activity.
To bridge the gap between laboratory-based workload studies and real-world operational demands.
To provide a comprehensive dataset for developing advanced workload monitoring systems.

Main Methods:

Collected multimodal data (EEG, ECG, respiration, skin temp, GSR, BVP, accelerometry) from 48 participants.
Manipulated physical activity levels using stationary bikes and treadmills.
Utilized wearable, off-the-shelf devices for realistic data acquisition.

Main Results:

Validated subjective (NASA-TLX, Borg scale), neural, and physiological data.
Established a robust dataset for analyzing mental workload during physical exertion.
Demonstrated the feasibility of using wearable sensors for workload assessment.

Conclusions:

The WAUC database offers a valuable resource for research on mental workload in physically active contexts.
Findings support the development of objective workload assessment tools for dynamic environments.
This work is crucial for improving safety and performance in demanding professions.
