Resumo
O crescente número de competições no basquetebol profissional tem aumentado o interesse no controlo das cargas dos jogadores. O rácio de carga de trabalho aguda:crónica é uma ferramenta muito comum para controlar a variação de carga nas equipas profissionais. No entanto, existem situações específicas em que o ACWR é limitado se não existirem valores históricos de carga disponíveis. O objetivo desta intervenção foi analisar a carga de trabalho de uma equipa profissional de basquetebol através do ACWR, incluindo uma revisão retrospetiva da sua curva para aqueles cenários em que se pretende obter valores precisos de risco de lesão sem os valores de carga anteriores dos jogadores. Participou neste estudo uma equipa profissional masculina de dez jogadores. Foram utilizados dispositivos inerciais da marca WIMU Pro para quantificar a carga dos jogadores durante o treino. As variáveis deste estudo foram a carga externa objetiva e subjectiva, a carga aguda e a carga crónica. Os resultados mostram a existência de lesões quando a carga é aumentada de forma desproporcionada e entra em valores de risco muito elevados. A incidência de lesões é de 20% quando os valores de risco são ultrapassados. O estudo corrobora que o rácio carga de trabalho aguda:crónica é uma ferramenta prática e útil para monitorizar a carga e a sua evolução ao longo do mesociclo sem uma análise estatística mais aprofundada. Além disso, é útil para saber quando controlar as cargas dos jogadores de um ponto de vista eminentemente prático, encontrando relações não causais com o aparecimento de lesões. Recomenda-se uma revisão retrospetiva dos valores se se pretender aperfeiçoar o valor do risco de lesão nas medições em que não se dispõe de taxas de carga pré-intervenção.
