Die klinische Studie NCT06651619 ist eine interventionsstudie zur Untersuchung von Dehydration und hat den Status offene rekrutierung. Die Studie startete am 1. Oktober 2024 und soll 108 Teilnehmer aufnehmen. Durchgeführt von PepsiCo Global R&D ist der Abschluss für 30. Juni 2025 geplant. Die Daten von ClinicalTrials.gov wurden zuletzt am 23. Oktober 2024 aktualisiert.
Kurzbeschreibung
Sports science testing by investigators at Gatorade Sports Science Institute has revealed that many athletes arrive at practice with a high urine specific gravity indicating they are hypohydrated. Though the data showed that most athletes don't lose more than 2% of their body weight in sweat during a training session, it is not known what the cumulative effects of living and training in a hot environment are over the course of a week. Previous research has indicated that prescribing fluid intake is more effective than education in improving drinking behavior during exercise. No studies to date have compared the impact of fluid intake prescription versus education in adolescent boys and girls playing outdoor and indoor sports.

Comparing sexes and training environment may provide more clarity around potential barriers and challenges to proper hydration for each environment.

Ausführliche Beschreibung
This study will implement a parallel design with 4 sports team groups: 1) Indoor girls, 2) Indoor boys, 3) Outdoor girls, and 4) Outdoor boys. Each group of 36 per groups will be randomized into 1 of 3 conditions: 1) control (no intervention), 2) hydration education intervention, 3) prescribed hydration and education intervention. Athletes will be observed for three practices per week for 2 weeks. Practices are separated by at least 48 hours.

ExperimentellHydration Education between Week 1 and Week 2
In-depth education session regarding the effects of dehydration, the performance benefits of proper hydration, and how to properly hydrate before, during, and after activity. Pre-practice urine specific gravity (USG), pre- and post-practice body mass, thirst scale measures. Fluid intake during practice (whatever the team is drinking).
Hydration Education
30-60 minutes
ExperimentellHydration Education between Week 1 and Week 2 plus Prescribed Hydration Week 2
In-depth education session regarding the effects of dehydration, the performance benefits of proper hydration, and how to properly hydrate before, during, and after activity. Pre-practice urine specific gravity (USG), pre- and post-practice body mass, thirst scale measures. Provided a standard amount of bottled water to drink the evening prior (1 liter) and in the two hours before practice (20 oz). Fluid intake will be recorded in an intake log. Subjects will be permitted to eat or drink whatever they like in addition to the prescribed fluid. Fluid intake during practice (whatever the team is drinking).
