Introdução: A determinação do limiar anaeróbio (LAn) é importante na individualização da prescrição do treinamento aeróbio. Objetivo: Comparar e verificar a concordância das respostas de consumo de oxigênio (VO2), frequência cardíaca (FC) e índice de esforço percebido (IEP) correspondentes ao LAn determinado através dos métodos ventilatório (LV) e ponto de deflexão da frequência cardíaca (PDFC) durante um teste incremental no meio aquático realizado por idosas treinadas. Métodos: Nove idosas (64,3 ± 4,4 anos), engajadas em um programa de hidroginástica nos últimos três meses, realizaram um teste máximo incremental com o exercício de corrida estacionária. O teste iniciou com uma cadência de 70 b.min-1 durante 2 min, seguida de aumentos de 15 b.min-1 a cada 2 min até a exaustão. Dados de VO2, FC e IEP foram medidos ao longo do teste. O LAn foi identificado para cada método por três fisiologistas experientes. Teste T pareado e análise de Bland-Altman foram utilizados para a análise dos dados (α=0,05). Resultados: Não houve diferença entre os métodos LV e PDFC (p>0,05) e a análise de Bland-Altman demonstrou concordância aceitável entre eles para todas as variáveis analisadas (VO2: 22,9 ± 5,1 vs. 23,5 ± 4,7 ml.kg-1.min-1, IC95%: -3-+4 ml.kg-1.min-1; FC: 147 ± 11 vs. 147 ± 11 b.min-1, IC95%: -9-+8 b.min-1; IEP: 16 ± 1 vs. 16 ± 1, IC95%: -2-+3). Conclusão: Com base nesses achados, sugere-se que a FC e o IEP determinados pelo PDFC podem ser utilizados como parâmetros válidos e ferramentas práticas de campo para a prescrição de intensidade de exercícios de hidroginástica em idosas treinadas.
