However, obtaining these measurements can be an invasive, time-consuming process. Hydration status may be detectable by analyzing blood flow patterns of the superficial (just under the skin) blood vessels. Wearable devices are now abundant among the general population, and despite attempts from several groups, a hydration status metric based on noninvasive wearable device metrics has not been developed. With wearables, a light source connected to an optical sensor transmits and reflects light through the body. The light sensor detects absorption of the light based on wavelength measurements of the detected light. Absorption of specific wavelengths of light energy is dependent upon the amount of oxygenated blood in the vessels. When the vessels expand and relax, the amount of blood volume in the observed tissue increases and decreases potentially causing a shift in the photoplethysmography (PPG) wave detected by the wearable. The shift in the shape of the PPG wave may be detected in a way that indicates the relative change in tissue hydration levels. However, to our knowledge, no wrist worn device that utilizes PPG has been successfully able to predict hydration status. Therefore, this study aims to utilize photoplethysmography (PPG) technology in a wearable device to accomplish this approach to hydration monitoring.",[28],"RECRUITING","2026-04-03",{"date":88,"type":33},"2026-04-09",{"date":90,"type":22},"2026-04-01",{"date":92,"type":22},"2026-10",{"name":94,"class":40},"PepsiCo Global R&D",2,{"id":97,"slug":98,"hasResults":11,"nctId":99,"briefTitle":100,"officialTitle":100,"acronym":4,"eligibilityCriteria":101,"healthyVolunteers":16,"sex":17,"minAge":18,"maxAge":102,"enrollmentInfo":103,"targetDuration":4,"studyType":23,"phases":105,"briefSummary":106,"conditions":107,"keywords":109,"overallStatus":85,"whyStopped":4,"lastUpdateSubmitDate":112,"lastUpdatePostDateStruct":113,"startDateStruct":115,"completionDateStruct":117,"leadSponsor":118,"locationsCount":41},"100615919","the-effect-of-hydration-status-on-substrate-oxidation-at-rest-and-during-light-and-moderate-exercise-100615919","NCT07298863","The Effect of Hydration Status on Substrate Oxidation at Rest and During Light and Moderate Exercise","Inclusion Criteria:\n\n* Subject is male or female\n* If female, subject is not pregnant (based on self-report)\n* If female, subject has stopped taking birth control medication or removed long-acting reversible contraceptive \\>6 months at start of the study\n* If female, subject has normal menstrual cycle (21-35 days)\n* If female, subject is willing to track their menstrual cycle\n* If female, subject has a smartphone compatible for application to track menstrual cycle (female only) and\u002For wearable data (females and males)\n* Subject is 18-35 years of age, inclusive\n* Subject body mass index (BMI) is between 18.5-25 kg\u002Fm2\n* Subject is at least recreationally active (engaged in moderate-intensity, intermittent, or steady-state exercise at least 3 days per week for at least 60 min at a time)\n* Subject is accustomed to cycling for at least 60 min\n* Subject does not smoke (or has quit for at least 6 months)\n* Subject is not taking medication that may interfere with the study (e.g., diuretics, laxatives, or weight loss drugs)\n* Subject has no health conditions that would interfere with the study as indicated on the general health questionnaire (GHQ) e.g. cardiovascular, renal, or metabolic diseases\n* Subject is not actively involved in weight loss intervention (dieting and\u002For anti-obesity medications)\n* Subject is not allergic to adhesives (e.g., medical tape)\n* Subject is willing to avoid alcohol consumption 24 hours prior to visit(s)\n* Subject is willing to fast overnight (\\~8-12 hours)\n* Subject is willing to refrain from vigorous exercise for 24 hours (light physical activity only)\n* Subject is willing to be shaved at patch or electrode site, if necessary\n* Subject is willing to eat the exact same food the day prior to each visit to the laboratory\n* Able to speak, write, and read English\n* Provision of written consent to participate\n\nExclusion Criteria:\n\n* Subject has participated in a clinical trial within the past 30 days\n* Subject has participated in any PepsiCo trial within past 36 months\n* Subject has a condition or is taking medication that the investigator believes would interfere with his\u002Fher 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\n* Subject is allergic to alcohol (alcohol pre pads are used for blood draws\n* If female, subject is taking birth control medication or has long-acting reversible contraceptive\n* If male, subject is undergoing hormone therapy to alter testosterone levels (injections, transdermal patch, pill, etc.)\n* 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 product.
