Resumo

Este estudo investigou as variações de CT em jogadores sub-17 (U17) e sub-19 (U19) de futebol sub-elite, com foco na integração de medidas de carga externa e interna. Com recurso a sistemas de posicionamento global (GPS) e a Percepção Subjetiva de Esforço (PSE), o estudo recolheu dados de 24 sessões de treino ao longo de seis semanas de pré-temporada. As métricas de GPS, como distância total, corrida em alta velocidade e distância percorrida em sprints, quantificaram as demandas físicas, enquanto a PSE avaliou o esforço subjetivo. Participaram no estudo 26 jogadores (13 U17, 13 U19), tendo sido comparados os padrões de CT entre as categorias etárias e ao longo dos dias de treinamento. Os resultados revelaram diferenças mínimas na carga externa entre os jogadores U17 e U19, com os jogadores U19 a apresentarem métricas ligeiramente superiores de corrida em alta velocidade e sprints. Os valores da PSE foram consistentes entre os grupos, confirmando sua confiabilidade na avaliação do esforço percebido. A análise de regressão destacou associações significativas entre a PSE e as variáveis de carga externa, como velocidade média e máxima, enfatizando a interação entre medidas objetivas e subjetivas. A análise realizada com recurso a um heat map demonstrou ainda as correlações entre as variáveis de CT, enfatizando a relação dinâmica entre as solicitações físicas e a percepção de esforço. Os achados sustentam o uso combinado de métricas de GPS e PSE para um monitoramento abrangente de CT, fornecendo uma estrutura para equilibrar solicitações de treino e bem-estar dos jogadores.
