Effects of Hydration Educational Intervention in High School Football Players
Abstract
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, 24-hour WC increased significantly in the EI (EI: 888 ± 713 ml; t (19) = −5.685, p < 0.001, CI 95%: [−1,208.9 to −560.0]) but not NI (119 ± 583 ml; t (20) = −0.915, CI 95%: [−392.0 to 153.5]) and EI increased FC by 19%, whereas NI showed a 6% FC decrease. There were no significant group ( F (1,19) = 0.025, p = 0.876, = 0.001) or interaction effects for hydration knowledge ( F (2,38) = 0.677, p = 0.514, = 0.034). Educational intervention improved hydration status and behaviors despite no change in knowledge. Hydration education should be implemented and reinforced by team personnel as benefits to an EI are reduced at 24-days post-intervention.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
In the citing paper
“Twenty-seven unique studies (7, 8, 11, 13–24, 28–39) were included.”
In the citing paper
“Several included studies evaluated hydration education in youth American football, volleyball, soccer, and mixed athletic settings, reporting favorable changes in knowledge or short-term hydration status when education is combined with objective feedback and practical cues (7, 8).”
In the citing paper
“Atkins et al. (8) used a brief education session, urine-color charts, water bottles, and hydration feedback in high-school football players, improving urine specific gravity and water intake at 3 days”
In the citing paper
“Moderate judgments in the original ROBINS-I set generally occurred when studies included comparator groups, structured delivery, repeated assessments, objective hydration or anthropometric measures, or more detailed dietary assessment, although residual confounding remained (7, 8, 11, 16, 17, 30, 34, 38).”
In the citing paper
“although effects were not maintained at 24 days”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
