The Hydration Status of Female Collegiate Soccer Players Over Consecutive Training and Match Days

Purpose: Hydration has been shown to play a pivotal role in sport. Soccer is a team sport in which the integrity of all players is vital for team performance; thus, individual player hydration status is important. The primary aim of this study was to investigate the hydration status of female collegiate soccer players during regular season. Methods: Sixteen collegiate female soccer players (age: 20.4 ± 0.8 years; height: 163.6 ± 6.9 cm; weight: 65.3 ± 12 kg) provided urine over 9 days to monitor their hydration status. Hydration was determined by urine specific gravity (Usg). Usg was analyzed in the morning (AM) and in the afternoon before practice/game (PM). Results: All 16 players were at least minimally hypohydrated (Usg \u3e 1.010) in the AM on 5 of the 9 days tested. Players had significantly higher Usg values in the AM as compared to PM (F(1,250) = 23.09; p \u3c 0.0001); however, there was no significant time*day interaction (F(1,250) = 1.98; p = 0.16). Conclusion: Data show a high prevalence of hypohydration occurring in this specific population. This sub-optimal hydration status could be a cause for concern in terms of overall performance. Efforts should be made to integrate hydration interventions and daily monitoring to minimize hypohydration in players

O futebol é um esporte coletivo no qual a integridade de todos os jogadores é vital para o desempenho da equipe; portanto, o estado de hidratação de cada jogador é importante. O objetivo principal deste estudo foi investigar o estado de hidratação de universitárias jogadoras de futebol do sexo feminino durante a temporada regular.Métodos: Dezesseis universitárias jogadoras de futebol (idade: 20,4 ± 0,8 anos; altura: 163,6 ± 6,9 cm; peso: 65,3 ± 12 kg) forneceram amostras de urina por 9 dias para monitorar seu estado de hidratação. A hidratação foi determinada pela gravidade específica da urina Usg. Sua Usg foi analisado pela manhã (matutino) e à tarde (vespertino) antes do treino ou jogo. Resultados: As 16 jogadoras estavam minimamente hipohidratadas (Usg > 1.010) no período matutino em 5 dos 9 dias medidos. As jogadoras apresentaram valores de Usg significativamente maiores no período matutino em comparação ao vespertino (F (1.250) = 23,09; p <0,0001); no entanto, não houve interação tempo * dia significativa (F (1.250) = 1,98; p = 0,16).Conclusão: os dados mostram uma alta prevalência de hipohidratação nesta população específica. Este estado de hidratação abaixo do ideal pode ser uma preocupação em termos de desempenho geral. Devem ser feitos esforços para integrar intervenções de hidratação e monitoramento diário para minimizar a hipohidratação em jogadoras.Propósito: Se ha demostrado que la hidratación juega un papel fundamental en el deporte.

El objetivo principal de este estudio fue investigar el estado de hidratación de las jugadoras universitarias de fútbol durante la temporada regular. Métodos: Dieciséis jugadoras universitarias de fútbol (edad: 20.4 ± 0.8 años; estatura: 163.6 ± 6.9 cm; peso: 65.3 ± 12 kg) proporcionaron muestras de orina durante 9 días para controlar su estado de hidratación, la cual se determinó por la gravedad específica de la orina (Usg). La Usg se analizó en la mañana (AM) y en la tarde antes del entrenamiento o el juego (PM). Resultados: Las 16 jugadoras estaban al menos mínimamente hipohidratadas (Usg > 1.010) en la AM en 5 de los 9 días medidos. Las jugadoras tuvieron valores Usg significativamente más altos en AM en comparación con PM (F (1,250) = 23.09; p < 0.0001); sin embargo, no hubo interacción significativa de tiempo * día (F(1,250) = 1.98; p = 0.16). Conclusión: los datos muestran una alta prevalencia de hipohidratación en esta población específica. Este estado de hidratación subóptimo podría ser motivo de preocupación en términos de rendimiento general. Se deberían hacer esfuerzos para integrar las intervenciones de hidratación y el monitoreo diario para reducir al mínimo la hipohidratación en las jugadoras
