Palavras-chave:
Treinamento Polarizado, Ciclismo Off-Road, XCO, endurance, competiçãoResumo
Para melhorar o desempenho em desportos de resistência, é importante incluir treino de alta e baixa intensidade, mas não existe uma prática universalmente aceite nem evidências científicas claras que permitam afirmações fiáveis sobre a predominância de um método de treino específico. Este ensaio clínico randomizado comparou os efeitos de um modelo de treinamento polarizado (POL) a um modelo de treinamento de baixa intensidade (LIT) nos parâmetros fisiológicos e no desempenho da corrida olímpica cross-country (XCO) de mountain bike em dezoito atletas competitivos de XCO (17,9 ± 3,6 anos). A superioridade de um dos dois métodos não pôde ser demonstrada neste estudo. Os resultados não mostraram diferenças estatisticamente significativas entre POL e LIT, uma vez que ambas as intervenções conduziram a ligeiras melhorias. No entanto, uma pequena tendência para melhores efeitos para POL foi observada na potência do ciclismo durante a corrida (4,4% vs. –2,2%), na dose de 4 mmol/L (6,1% vs. 2,8%) e no limiar de lactato anaeróbico individual (5,1 % vs. 2,3%) e para desempenho aeróbio máximo (4,4% vs. 2,6%), mas não para esforços máximos com duração de 10 a 300 s. Apesar da falta de superioridade significativa neste e em alguns outros estudos, muitos atletas e treinadores preferem o POL porque produz efeitos pelo menos equivalentes e requer menos tempo de treino.
