Summary

This is primarily an experimental study investigating methods of temperature measurement / heat strain detection. In the calibration study, there are different skin temperature sensor types, and in the prediction study there are different methods for determining heat strain, including conventional methods (rectal, gastro-intestinal), the development of a prediction model, and an index based on heart rate variability.

Conditions

  • Heat Stress

Interventions

OTHER

Heat strain

The experimental procedure comprised 15 min baseline seated rest (23.2 ± 0.3°C, 24.5 ± 1.6% relative humidity), followed by 15 min seated rest and cycling in a climatic chamber (35.4 ± 0.2◦C, 56.5 ± 3.9% relative humidity; to +1.5◦C or maximally 38.5°C rectal temperature, duration 20-60 min), with a final 30 min seated rest outside the chamber.
