Only the study team can determine whether someone qualifies for participation.

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 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

Treatment and study plan

Gx sweat patch

Other

Adhesive-backed flexible epidermal wearable regional sweat patch to collect and analyze sweat via microfluidics and colorimetric assay

Reference sweat patch

Other

Adhesive Tegaderm with absorbent pad regional sweat patch to collect sweat, followed by standard benchtop gravimetry and ion chromatography methods to analyze sweat

Primary outcomes

  1. Regional sweat chloride concentration

    Time frame: 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 outcomes

  1. Regional sweating rate

    Time frame: 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

  2. Whole body sweating rate

    Time frame: 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
