Brief summary
To determine the validity of the Gx Sweat Patch in measuring sweating rate and sweat chloride concentration during moderate-high intensity practice against well-established reference methods in field conditions with basketball athletes
Interventions
OTHERGx sweat patch
Adhesive-backed flexible epidermal wearable regional sweat patch to collect and analyze sweat via microfluidics and colorimetric assay
OTHERReference sweat patch
Adhesive Tegaderm with absorbent pad regional sweat patch to collect sweat, followed by standard benchtop gravimetry and ion chromatography methods to analyze sweat

Inclusion criteria
* 18-40 years of age * Subject is participating in training/competition with the NBA G-league * Subject is participating in a coach led practice
Exclusion criteria
* Subject has an allergy to adhesives (e.g., experiences rash reactions to typical adhesive bandages) * Subject has participated in a clinical trial within past 30 days * Subject has participated in any PepsiCo trial within past 6 months * Subject has a condition the investigator believes would interfere with his/her ability to provide informed consent, comply with the study protocol, which might confound the interpretation of the study results or put the person at undue risk
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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 |
