Fluid Intake in Athletes, Sweat Chloride Concentration in Athletes, Sweating Rate in Athletes
Conditions
Keywords
sweat, hydration, wearable, exercise
Brief summary
The main objectives are to determine the validity of a Smart Cap in measuring fluid intake during running and fitness exercise and the validity of a Smart Sweat Patch in measuring sweat rate and sweat chloride concentration during outdoor cycling, running, and fitness exercise. A secondary objective is to compare regional sweating rate and sweat electrolyte concentrations (sodium, chloride, and potassium) on contralateral arms with vs. without tattoos.

Intervention model description
Each subject will serve as his or her own control. We will compare the Test and Reference methods during moderate intensity self-paced training runs, coach-led fitness sessions, and/or group outdoor cycling rides.

Inclusion criteria
* Subject is male or female * Subject is 16-65 years of age * Subject is moderately-trained (participates in regular outdoor fitness (\ 1 h), cycling (1-2 h), or running (0.5-1 h) sessions ≥2x per week) * Subject is participating in an instructor-led fitness session, typical training run, or group bicycle ride
Exclusion criteria
* Subject is pregnant * Subject is a smoker * Subject is taking a medication or oral supplement that could interfere with study results * Subject has an allergy to adhesives (e.g., experiences rash reactions to typical adhesive bandages) * Subject has ≥ 2 cardiovascular risk factors as assessed on the General Health History Questionnaire * 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 * Subject is employed by, or has a parent, guardian or other immediate family member employed by, a company that manufactures any products that compete with any Gatorade products. If subject is unsure if a company would be considered a competitor to Gatorade they will be asked to please let the study investigator know the name of the other company and the nature of their relationship to that company before they sign the informed consent.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Fluid intake | Change from baseline to up to 1 hour of exercise | Smart Cap (sensor) versus Reference method (bottle weight) |
| Regional sweating rate | Change from baseline to up to 2 hours of exercise | Sweat Patch versus Reference patch method |
| Regional sweat chloride concentration | Change from baseline to up to 2 hours of exercise | Sweat Patch versus Reference patch method |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Regional sweating rate with versus without tattoos | Change from baseline to up to 2 hours of exercise | Reference sweat patch method |
| Regional sweat sodium and potassium with versus without tattoos | Change from baseline to up to 2 hours of exercise | Reference sweat patch method |
| Whole body sweat rate | Body mass change from baseline to up to 2 hours of exercise | Scale weight |
