Impact of Reflective Roadways on Simulated Heat Strain at the Tokyo, Paris, and Los Angeles Olympics

This study models the progression of heat strain in elite marathon and race walk athletes competing on traditional dark asphalt, reflective pavement, or shaded asphalt in past and future Olympic Games (Tokyo (Sapporo), Paris, Los Angeles).

Observed weather or expected climate conditions for three Olympic cities, along with modeled mean radiant temperature differences across the three surface types, were fed into the joint system (JOS-3) thermoregulation model. Resultant changes to heat strain parameters of core temperature (Tcr) and mean skin temperatures (T ̅_sk), as well as skin wettedness and cardiac output, were modeled.
The gathered weather or climate data can be useful in future work on these events at the Olympics, as well as the modeled mean radiant temperature (MRT), and the final modeled heat strain parameters using the JOS-3 thermoregulation model. These outputs and the Python codes for all (MRT and JOS-3) are provided.

For 7 different Olympic events (from Tokyo (Soporro), Paris, and LA) are provided. Each event contains the model code (Python) and the output files. An input folder for modeling Mean Radiant Temperature also includes the input meteorological data (based on climate norms).
