Whole-Body Sweat Rate Prediction: Outdoor Running and Cycling Exercise

We report the development and validation of new proprietary whole body sweat rate prediction models for outdoor running and outdoor cycling using simple activity and environmental inputs. Separate sweat rate models were also developed and tested for situations where all four environmental parameters are not available, and some must be subsequently estimated by the user via a simple rating scale. All models are freely accessible through an online calculator: https://sweatratecalculator.com . These models, via the online calculator, will enable individualized hydration management for training or recreational cycling or running in an outdoor environment.
