Predicted vs. measured whole body sweat rate (SR) values for the independent validation trials using measured environmental variables. Male (closed symbol) and female (open symbol) subject individual data points are plotted for outdoor running (left) and cycling (right) exercise. Credit: Journal of Applied Physiology (2024). DOI: 10.1152/japplphysiol.00831.2023 For the first time, researchers have developed a validated tool that lets athletes predict their rate of whole-body sweat loss. The tool consists of precise equations that help people regulate the amount of fluids they drink over three hours while active in warm Read More
