Whole body sweat rate prediction: indoor treadmill and cycle ergometer exercise.
J Appl Physiol (1985)
October 2024
Article Synopsis
- The article focuses on creating and validating equations to accurately predict whole body sweat rates during indoor cycling and treadmill exercises, based on measurable power output and various environmental conditions.
- It utilized a significant number of trials (both for model development and validation) across different temperatures, humidity levels, and exercise intensities, ensuring robust data for the prediction models.
- The resulting equations showed high accuracy, with a low mean absolute error in predictions and a significant percentage of variance accounted for, and they are now publicly accessible for practical use.
Whole body sweat rate prediction: outdoor running and cycling exercise.
J Appl Physiol (1985)
June 2024
Article Synopsis
- The study aimed to create and validate prediction equations for whole body sweat rates during outdoor cycling and running using basic activity and environmental factors.
- Data were collected from 182 running trials and 158 cycling trials under varying temperatures, with models developed and validated separately for each sport.
- The resulting prediction models showed high accuracy (with minimal errors) and can help individuals manage hydration during outdoor exercises, and they are available for public use online.
Article Synopsis
- Researchers used wearable sensors to monitor heart rate and movement in US Army Rangers and Combat Engineers during intense marches, aiming to predict exertional heat stroke (EHS) early on.
- Data from 478 participants were analyzed using machine learning to assess physical strain and stress, successfully predicting EHS up to 69 minutes before it occurred in three cases.
- The study suggests that this predictive method can be adapted to other activities and improved with new sensor technology, potentially aiding in health intervention strategies.
Exertional heat stroke is a true medical emergency with potential for organ injury and death. This consensus statement emphasizes that optimal exertional heat illness management is promoted by a synchronized chain of survival that promotes rapid recognition and management, as well as communication between care teams. Health care providers should be confident in the definitions, etiologies, and nuances of exertional heat exhaustion, exertional heat injury, and exertional heat stroke.
