You will be asked to log food\u002Ffluid intake 24hr leading into trials. We ask that you match your diet for both trials, as much as possible. Also, we ask that you match caffeine consumption prior to trials. Lastly, we ask that you refrain from strenuous exercise and alcohol consumption for at least 12hrs leading into trials. Either of these exclude your participation in the study for safety reasons. You will be asked to provide a small urine sample upon arrival to the lab before trials. The purpose of this is to verify hydration prior to exercise in the heat. If you are not hydrated upon arrival, you will be provided and asked to drink 16oz (a bottle) of water prior to the trial. Just prior to, and following each long trial, you will be asked to provide a small saliva sample. To do this, you will be asked to actively produce saliva and guide it into a small container. This process takes \\\u003C5min. Next, you will have your nude body mass measured and you will be instrumented with a labbased sweat collection patch (large band-aid on the forearm), and the Hdrop sweat detection device on your left upper arm. The Hdrop will be synced with electronic applications (phone apps) to assure data collection. You will then self-insert a rectal thermistor \\~15 cm past the anal sphincter to monitor core temperature throughout exercise (for safety purposes). You will also be fitted with a heart rate strap that goes around your chest. You will then be asked to enter the environmental chamber and exercise for 30min. This will serve as the short exercise trial aiming to assure comfort with the 120min exercise trials. Data will be collected during the short trial and comparisons will be made for the longer, 120min trials. The environmental chamber will maintain a consistent temperature (80-100 degrees F) and humidity (40 to 60 % relative humidity). You will be monitored for safety throughout exercise in all 3 trials, and you will be allowed to cycle (stationary bike) or run or walk (treadmill) at your own pace\u002Fintensity. Pace and intensity will be recorded during the first trial and attempts will be made to match exercise intensity for subsequent trials. Fluid consumption will be allowed during trials and will be matched between trials. In both trials, you will be allowed to drink for a 5min period at each 30min interval (30-35min, 60-65min and 90-95min). We will provide a sport drink of your flavor choice during exercise.",[28,29,30],"Sweat Rate","Heat Effect","Sweat Sodium Concentration",[32,33,34,35],"Sweat rate","Exercise in the heat","Sweat sodium","Validity","NOT_YET_RECRUITING","2026-03-09",{"date":39,"type":40},"2026-03-11","ACTUAL",{"date":42,"type":22},"2026-02-16",{"date":44,"type":22},"2026-08",{"name":46,"class":47},"University of Arkansas, Fayetteville","OTHER",{"id":49,"slug":50,"hasResults":11,"nctId":51,"briefTitle":52,"officialTitle":52,"acronym":4,"eligibilityCriteria":53,"healthyVolunteers":16,"sex":54,"minAge":55,"maxAge":4,"enrollmentInfo":56,"targetDuration":4,"studyType":58,"phases":4,"briefSummary":59,"conditions":60,"keywords":61,"overallStatus":67,"whyStopped":4,"lastUpdateSubmitDate":68,"lastUpdatePostDateStruct":69,"startDateStruct":71,"completionDateStruct":73,"leadSponsor":75,"locationsCount":78},"100592618","normative-data-for-sweating-rate-sweat-sodium-concentration-and-sweat-sodium-loss-in-female-athlete-100592618","NCT06995768","Normative Data for Sweating Rate, Sweat Sodium Concentration and Sweat Sodium Loss in Female Athlete","Inclusion Criteria:\n\nSubject is female\n\n* Subject is 13yrs+\n* Subject has been cleared for sport participation by their personal or team physician and\u002For coach-led practice\u002Ftraining.\n* Subject is participating in sport on the youth\u002F amateur\u002F collegiate\u002Fprofessional\u002Felite level\n* If under 18, a parental\u002Fguardian consent form will be completed.\n\nExclusion Criteria:\n\n* As this study is undertaken at the athletes training facility, the medical staff at the team\u002Fclub will advise on who should\u002F should not take part.\n* Subject has an allergy to adhesives (e.g., experiences rash reactions to typical adhesive bandages","FEMALE","13 Years",{"count":57,"type":22},500,"OBSERVATIONAL","The main objectives are to determine sweat sodium concentration \\[Na+\\], whole body sweat rate (WBSR) and rate of sweat sodium loss (RSSL) in female athletes aged 13 and above during their normal planned training session across various sports (basketball, soccer, volleyball, cheer, flag football and softball).",[28],[62,63,64,65,66],"sweat","sodium loss","sweat patch","athlete","healthy volunteer","RECRUITING","2025-05-21",{"date":70,"type":40},"2025-05-29",{"date":72,"type":40},"2025-04-22",{"date":74,"type":22},"2026-06-30",{"name":76,"class":77},"PepsiCo Global R&D","INDUSTRY",1]
