Effects of Hydration Educational Intervention in High School Football Players

Atkins, WC, McDermott, BP, Kanemura, K, Adams, JD, and Kavouras, S. Effects of Hydration Educational Intervention in High School Football Players. J Strength Cond Res 35(2): 385–390, 2021—The purpose of this study was to assess the effects of a one-time educational intervention (EI) on hydration behaviors, status, and knowledge. In a pre-test, post-test quasi-experimental design, 41 in-season American high school football players (16 ± 1 years) voluntarily participated. Teams were assigned to EI or no intervention (NI) groups. Educational intervention included a 5-minute presentation on hydration importance, self-assessment, urine-color charts, water bottles, and hydration status feedback. Baseline data included 24-hour fluid intake logs, urinalysis, and questionnaires. Data collection was repeated 3 and 24-days post-EI. Subjects provided urine samples and recorded fluid intake. Twenty-four hour mean fluid consumed (FC) and water consumed (WC) were calculated. Questionnaires quantified hydration knowledge. Significance was set a priori at p ≤ 0.05. Urine specific gravity was not significantly different at baseline (EI: 1.026 ± 0.006; NI: 1.023 ± 0.009; p = 0.118, confidence interval [CI] 95% [−0.001 to 008]), improved 3-days post-EI (EI: 1.017 ± 0.010; NI: 1.026 ± 0.007; p = 0.004, CI 95% [−0.015 to −0.003]), and was not different 24-days post-EI (EI: 1.021 ± 0.009; NI: 1.025 ± 0.007; p = 0.213, CI 95% [−0.008 to 002]) between groups. Three days post-EI, ...
