Analysis of the thermal comfort in cycling athletes

The analysis presented in this work is based on the in-situ measurements of both environmental and physiological parameters (i.e.: air temperature, relative humidity, true wind velocity, apparent wind velocity, skin temperature, clothing temperature, heat transfer resistance of the clothing, internal heat production) made over different athletes in different race conditions. The recorded data have been used as input for the model "RayMan" [1], [2] for the assessment of the thermal comfort using thermal indices such as Predicted Mean Vote (PMV) and Physiological Equivalent Temperature (PET). It should be noted that the apparent wind velocity, which is a fundamental parameter in this kind of analysis but often disregarded, is evaluated in relationship with the movement and the effort made by the cyclist.
