Impacto de 12 semanas de treinamento resistido na composição corporal, dor e capacidades físicas
Estudo em policias militares do interior da Amazônia
Resumo
Introdução: Policiais militares (PM) apresentam um estilo de vida sedentário, marcado por alterações na composição corporal, nas capacidades físicas e na percepção da dor. Por outro lado, o treinamento resistido (TR) atua de forma eficaz para a promoção de saúde nessa população. Objetivo: Analisar o efeito de um programa de TR na composição corporal, nas capacidades físicas, na ocorrência e intensidade de dor de PM atuantes no serviço administrativo do município de Santarém-Pará. Métodos: Estudo quase-experimental, com 19 policiais militares atuantes do serviço administrativo, em Santarém, Pará, Brasil, submetidos a 12 semanas de TR. Foram avaliadas, pré e pós-intervenção a composição corporal, força muscular, resistência muscular abdominal, flexibilidade e a dor. Os dados foram analisados por estatística descritiva e inferencial, adotando-se p<0,05. Resultados: O sexo feminino predominou (53 %) e a idade média foi de 34,89±7,02 anos. O TR reduziu a adiposidade corporal (p<0,05), aumentou a força muscular (p<0,001), a flexibilidade (p<0,001) e a resistência muscular localizada, evidenciada pelo maior número de repetições no teste de abdominal (p<0,001). Em relação à dor, verificou-se redução na ocorrência de regiões dolorosas (89,5 % vs. 57,9 %) e diminuição da intensidade da dor relatada pelos participantes (p<0,001). Conclusão: Os achados reforçam a importância do TR como estratégia eficiente na promoção de saúde, desempenho funcional e redução de queixas dolorosas em PM.
