Resumo

O exercício em intensidade autosselecionada (EIA) é uma abordagem simples para encorajar um estilo de vida ativo. Este estudo investigou se o EIA atende a intensidade recomendada para tratamento de hipertensão (i.e. moderada-vigorosa), e se a frequência cardíaca (FC), percepção de esforço (PSE) e resposta afetiva são reprodutíveis. Treze mulheres idosas hipertensas inativas (idade: 64,54 ± 4,16 anos; pressão arterial: 122,51/62,15 mmHg) realizaram duas sessões de EIA de 30 minutos ao ar livre.  FC de reserva (FCR), PSE e resposta afetiva foram avaliadas. Teste t pareado, coeficiente de correção intraclasse (CCI) e erro típico (ET) foram analisados. As participantes se exercitaram em intensidade moderada-vigorosa (≥ 40% da FCR). Não houve diferença na FCR (56,46 ± 8,01% vs. 59,08 ± 10,57%), PSE (11,26 ± 1,14 vs. 10,98 ± 1,52) e resposta afetiva (3,47 ± 1,13 vs. 3,38 ± 1,23; p > 0,05). A PSE apresentou excelente confiabilidade (CCI = 0,82; IC95%: 0,42; 0,94; p = 0,003). Houve baixa confiabilidade da FCR (CCI = 0,40; IC95%: -0,97; 0,82; p = 0,193) e resposta afetiva (CCI = 0,19; IC95%: -2,10; 0,76; p = 0,369). O ET foi de 8,11 bpm, 0,75 e 1,11 para FCR, PSE e resposta afetiva, respectivamente. Em conclusão, mulheres idosas hipertensas inativas parecem atender a intensidade recomendada para tratamento da hipertensão quando realizam EIA e relatam a atividade como leve-moderada e prazerosa. Embora apenas a PSE, e não a FCR e resposta afetiva, tenha mostrado boa reprodutibilidade. Os resultados parecem suportar o EIA como uma abordagem simples para encorajar um estilo de vida ativo nessa população.
