Objective:
The purpose was to characterize the physiological responses resulting from a newly developed treadmill firefighting simulation and to compare these responses with those induced by live fire and simulated firefighting activities reported in different studies.
Methods:
Forty participants (four women) (25 ± 6 years) performed a 25-minute treadmill firefighting simulation that consisted of various tasks completed on a typical work-rest cycle at an imposed rhythm in a temperate environment (ambient temperature: 22.6°C ± 0.6°C, relative humidity: 29.7% ± 11.6%).
Results:
Rectal temperature increased by 0.56°C ± 0.15°C; peak and mean oxygen consumption were 35.3 ± 3.3 and 20.8 ± 1.7 mL·kg -1 ·min -1 , respectively; and 1169 ± 182 L of air was used.
Conclusion:
These results show that the treadmill firefighting simulation induces similar physiological responses to those reported for live fire and simulated firefighting scenarios.

01:20Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
01:26Exercise Stress Test
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.

Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...
