Outcomes

Primary Outcomes

Regional sweat chloride concentration

Gx patch vs. reference patch during exercise. Gx patch analyzed by colorimetry via smartphone app. Reference patch analyzed with ion chromatography

Time frame: Average across a single practice session on 1 day

Secondary Outcomes

Regional sweating rate

Gx patch vs. reference patch during exercise. Gx patch analyzed by microfluidic reading with Smartphone. Reference patch analyzed with gravimetry

Time frame: Average across the same single practice session on the same 1 day as the primary outcome

Whole body sweating rate

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

Time frame: Measured one time to represent the average across the same single practice session on the same 1 day as the primary outcome
