Resfriamento da superfície da pele minimiza perda de desempenho aeróbio de jogadores de futebol amadorResfriamento.Futebol.Termorregulação.Desempenho.Cooling.Soccer.Thermoregulation.Performance.Educação FísicaO objetivo deste estudo foi analisar o efeito de diferentes estratégias de resfriamento no desempenho de salto, sprint e aeróbio de jogadores de futebol amador, em ambiente quente (acima de 28°C). Dez jogadores de futebol amador foram submetidos ao protocolo experimental que consistia numa sequência de testes (saltos, sprints e teste aeróbio Yo-Yo IR1) realizados em dois tempos de 45 min, separados por intervalo de 15 min no qual foram aplicadas as estratégias de resfriamento [ventilador (Vent e toalha molhada (Toa)] e controle (Con). O protocolo experimental foi conduzido em três sessões, com sete dias de intervalo entre elas. Familiarização ao protocolo experimental foi conduzida uma semana antes da primeira sessão. Na primeira sessão, os jogadores foram randomicamente alocados nos grupos Vent (n=4), Toa (n=3) e Con (n=3). Na segunda e terceira sessões, os atletas passaram pelas demais condições experimentais. Após aplicação das estratégias de resfriamento a temperatura da pele reduziu significativamente (p<0,001) e o desempenho no teste Yo-YO IR1 foi mantido para os grupos Vent e Toa, mas não para Con (p>0,05). Temperatura da pele foi inversamente correlacionada ao desempenho no teste Yo-YO IR1 (r=-0,414; p=0,013). Ainda, a sensação térmica foi diretamente correlacionada à potência de salto (r=0,386; p=0,019) e inversamente correlacionada à percepção de recuperação (r=0,373; p=0,023). O resfriamento realizado no intervalo contribui para redução da temperatura da pele e minimiza perda do desempenho aeróbio em jogadores de futebol.The aim of this study was to analyze the effect of different cooling strategies on jump, sprint and aerobic performance of amateur soccer players in warm environments (above 28° C). Ten amateur soccer players were submitted to the experimental protocol consisting of a sequence of tests (jumps, sprints and Yo-Yo IR1 aerobic test) performed in two 45-minute halves, separated by a 15-minute interval in which the cooling strategies were applied [Fan (Vent) and wet towel (Tow)] and control (Con). The experimental protocol was conducted in three sessions, with a seven-day interval between them. The demonstration and habituation for the experimental protocol, was conducted one week before the first session. In the first session, the players were randomly assigned to the Vent (n = 4), Toa (n = 3) and Con (n = 3) groups. In the second and third sessions, the athletes were submitted to the other experimental conditions. By executing the cooling strategies, skin temperature was significantly reduced (p <0.001) and performance in the Yo-YO IR1 test was maintained for the Vent and Toa groups, unlike for the Con group (p> 0.05). The skin temperature was inversely correlated to performance in the Yo-YO IR1 test (r = -0.414; p = 0.013). Moreover, the thermal sensation was directly correlated to the jump power (r = 0.386, p = 0.019) and inversely correlated with the recovery perception (r = 0.373, p = 0.023). The execution of cooling strategies between the two 45 min sections have contributed to reduce of the skin temperature and minimizes loss of aerobic performance in soccer players.Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorUniversidade Federal do Triângulo MineiroInstituto de Ciências da Saúde - ICS::Curso de Graduação em Educação FísicaBrasilUFTMPrograma de Pós-Graduação em Educação FísicaMENDES, Edmar Lacerda00103654518http://lattes.cnpq.br/7034181632957743BARROS, Cristiano Lino Monteiro de01324307625http://lattes.cnpq.br/2976367371704523TERRA, Mateus Petrachini2019-06-25T18:08:11Z2018-07-31info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdfTERRA, Mateus Petrachini.
