Arm && Interventions

Group	Intervention	Description
Validation. Reference sweat collection patch	Reference sweat patch	Right ventral forearm placement using a well-established methodology as published in peer-reviewed journals
Validation. Gx sweat collection patch	Gx sweat patch	Left ventral forearm placement using Epicore Biosystems Gx patch

Primary Outcome Measures

Name	Time	Method
Regional sweat chloride concentration	Average across a single practice session on 1 day	Gx patch vs. reference patch during exercise. Gx patch analyzed by colorimetry via smartphone app. Reference patch analyzed with ion chromatography

Secondary Outcome Measures

Name	Time	Method
Regional sweating rate	Average across the same single practice session on the same 1 day as the primary outcome	Gx patch vs. reference patch during exercise. Gx patch analyzed by microfluidic reading with Smartphone. Reference patch analyzed with gravimetry
Whole body sweating rate	Measured one time to represent the average across the same single practice session on the same 1 day as the primary outcome	Change in body mass from pre- to post-exercise, corrected for fluid/food intake and urine loss. Body mass measured to the nearest 0.01 kg using a digital platform scale
