Exercise Stress Test01:26

Exercise Stress Test

535
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.
Purposes

Stress Concentrations01:24

Stress Concentrations

387
Stress concentration is when stress intensifies near discontinuities such as holes or abrupt cross-sectional changes in a structural member. This localized stress can often surpass the average stress within the member. The stress distribution in flat bars, either with a circular hole or varying widths connected by fillets, can be determined experimentally using a photoelastic method. The results are based on ratios of geometric parameters like the ratio of the hole's radius to the smaller...

Responses to Heat and Cold Stress

13.9K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Thermal Stress01:09

Thermal Stress

2.6K
If the temperature of an object is changed while it is prevented from expanding or contracting, the object is subjected to stress. The stress is compressive if the object expands in the absence of constraint and tensile if it contracts. This stress resulting from temperature change is known as thermal stress. It can be quite large and can cause damage. To avoid this stress, engineers may design components so they can expand and contract freely. For instance, on highways, gaps are deliberately...

Stress Response System01:21

Stress Response System

223
The stress response system, also known as the fight-or-flight response, is the body's automatic physiological reaction to perceived threats. Hans Selye introduced the concept of General Adaptation Syndrome (GAS) to describe the predictable pattern of changes that occur in response to stress. GAS consists of three sequential stages: alarm, resistance, and exhaustion. This model helps explain how chronic stress can contribute to health problems.
Alarm stage
In the alarm stage, the body's...

Area of Science:

  • Psychophysiology
  • Mobile Health Technology
  • Biomedical Engineering

Background:

  • Mobile devices offer complex physiological data evaluation for interactive psychophysiological assessments.
  • Triggering psychological states via physiological data, like heart rate variability (HRV), requires robust algorithms, which are currently scarce.
  • Additional HRV reduction (AddHRVr) is a notable exception, designed to account for metabolic influences on cardiac activity.

Purpose of the Study:

  • To present an approach for deriving algorithm settings to automatically trigger psychosocial state assessments.
  • To analyze transient HRV changes using online data analysis in a sample of 38 firefighters.
  • To identify robust algorithm settings for triggering stress detection.

Main Methods:

  • Systematic manipulation and quantification of static and dynamic AddHRVr algorithm settings via binary triggers.
  • Application of multilevel models to predict objective stress increases over a 24-hour period.
  • Calculation of effect estimates (odds) and bootstrap power simulations to determine optimal settings.

Main Results:

  • Evidence suggests a dynamic AddHRVr algorithm can successfully trigger stress transitions.
  • The study identified specific algorithm settings with potential for automated stress assessment.
  • Effect estimates and power simulations provided insights into the robustness of different settings.

Conclusions:

  • A dynamic AddHRVr algorithm shows promise for triggering stress transitions in real-world settings.
  • This approach could facilitate future interactive psychophysiological assessments.
  • Further validation is recommended to confirm the efficacy of the dynamic AddHRVr algorithm.
