- W2108238369 abstract "O tAanis de campo A© um esporte disputado ao ar livre, necessitando de aA§Aµes especAficas de hidrataA§A£o para evitar comprometimento no desempenho e saAode. Desta forma, objetivou-se identificar a taxa de sudorese e o percentual de desidrataA§A£o de tenistas amadores adolescentes. Participaram do estudo oito atletas, do sexo masculino com mA©dia de idade de 14 ± 1,3 anos. Os dados foram coletados durante partidas da Etapa Mineira do Campeonato Brasileiro. A temperatura e umidade do ar mA©dia dos jogos foram, respectivamente, de 24± 0,8 ÂoC e 68± 0,6 UR. Os atletas foram pesados antes do aquecimento e logo apA³s o tA©rmino das partidas. Identificou-se a ingestA£o de liquido de cada atleta e o tempo de duraA§A£o da partida para cAilculo da taxa de sudorese. Avaliou-se o estado de hidrataA§A£o pela diferenA§a da massa corporal antes e apA³s a atividade e pela gravidade especAfica da urina. A hidrataA§A£o dos atletas foi realizada com Aigua. Utilizou-se a estatAstica descritiva e o Teste t pareado, sendo considerado como estatisticamente significante p<0,05. A maioria (62,5%) produziu entre 798 e 894 mL de suor por hora de atividade e ingeriu mais de um litro de lAquido. Nenhum dos atletas ultrapassou o Andice de 1% de desidrataA§A£o, porA©m 62,5% iniciaram a partida hipohidratados e 50% terminaram o jogo na mesma condiA§A£o. O estado de hipohidrataA§A£o inicial permite inferir que os atletas podem ter competido sem estar com seu mAiximo potencial fisiolA³gico. Faz - se assim necessAirio uma conscientizaA§A£o da importA¢ncia da hidrataA§A£o prA©via A atividade. ABSTRACTSweat rate, liquid consumption and hydration of amateur tennis players in stage of Brazilian ChampionshipTennis is a sport played outside, requiring specific actions of hydration to avoid compromising performance and health. Thus, we aimed to identify the sweat rate and dehydration percentage of adolescent amateur tennis players. The study included eight athletes, male with a mean age of 14 ± 1,3 years. Data were collected during matches of the MG Stage of Brazilian Championship. The average temperature and humidity of air in the games were, respectively, 24 ± 0,8 Âo C and 68 ± 0,6 RH. Athletes were weighed before the warm-up and just after the end of matches. It was identified the fluid intake of each athlete and match duration for calculating the sweat rate. It was evaluated the hydration status by the difference of body weight before and after the activity and by the specific gravity of urine. The hydration of athletes was performed with water. It was used the descriptive statistics and paired T-test, being considered as statistically significant p<0,05. The majority (62,5%) produced between 798 and 894 ml of sweat per hour of activity and drank more than one liter of liquid. None of the athletes exceeded the rate of 1% of dehydration, but 62,5% started the match hypo-hydrated and 50% finished the game in the same condition . The initial state of hypo-hydration allows us to infer that athletes may have competed without being with their maximum physiological potential. Thus, it becomes necessary an awareness of the importance of hydration prior to the activity." @default.
