Resumo
Treinamentos resistidos são cada vez mais empregados para manutenção da saúde ou tratamento de doenças. Dentre eles, o treinamento resistido funcional tem se difundido, entretanto carecem estudos que avaliem sua influência em modulação autonômica (MA), composição corporal, força muscular (FM) e parâmetros cardiorrespiratórios em pacientes com síndrome metabólica (SM). Este estudo buscou analisar e comparar os efeitos de treinamento resistido convencional vs funcional sobre a MA, composição corporal, FM e parâmetros cardiorrespiratórios na SM. Foram avaliados 50 sujeitos com SM de ambos os sexos, de 40 a 60 anos, divididos em grupos, sendo no primeiro artigo explorado treinamentos resistidos funcional e convencional, com 19 sujeitos em cada grupo e no segundo artigo três grupos (convencional, funcional e controle) com 19 sujeitos nos grupos treinamentos e 12 controle. Os grupos treinamentos funcional e convencional foram periodizados por 12 semanas, totalizando 30 sessões. Para a análise da MA índices de variabilidade da frequência cardíaca foram obtidos nos domínios do tempo (RMSSD e SDNN) e da freqüência (LF, HF, LF/HF), índices geométricos (plot de Poincaré, interpolação triangular dos intervalos NN (TINN), índice triangular (RRtri) e índices no domínio do caos (Caóticos Globais e Dimensão Fractal Higuchi). Para avaliação da FM foi usado teste 1RM, para composição corporal usou-se bioimpedância, e os parâmetros cardiorrespiratórios avaliados foram pressão arterial, frequência cardíaca e saturação de O2. Os resultados mostraram que o treinamento resistido funcional é superior ao convencional para benefícios em MA com maior ação do sistema nervoso parassimpático, embora no domínio do caos não houve diferenças entre os grupos. Apenas o funcional melhorou pressão arterial (redução de 10 mmHg para sistólica e 7mmHg para diatólica) ao comparar valores pré e pós treino. Entretanto ambos aumentaram FM semelhantentemente ( diferença entre os grupos p > 0.127) e nenhum deles promoveram alterações em composição corporal. Conclui-se que o treinamento resistido funcional é superior ao convencional para promover melhores respostas da MA e redução de pressão arterial, ambos os treinos aumentam FM e nenhum deles alteram composição corporal em indivíduos adultos com SM após 30 sessões de treinamento periodizado.
Resistance training have been applied on health promotion and disease´s treatments. Among the tipes of resistance training, is the functional resistance training which has been highlighted in recent times. However lacks studies evaluating its influence on aspects such as autonomic modulation (AM), body composition , muscular strength (MS) and cardiorespiratory parameters in patients with metabolic syndrome (MetS). This study analyze and compare the effects of conventional resistance training vs. functional resistance training on AM, body composition, MS and cardiorespiratory parameters in MetS patients. For its realization 60 subjects of both sexes, aged between 40 and 60 years old, who have MetS were evaluated and divided by groups: for the first paper two training groups (functional vs conventional) with 19 subjects each one, and for the second paper tree groups (functional, conventional and control) with 19 subjects for each training group and 12 controls. The FRT and CRT groups were periodized by 12 weeks, totalizing 30 training sessions. The autonomic modulation indexes of heart rate variability were used to evaluate AM and these indexes were obtained in the time domain (RMSSD and SDNN), frequency domain (LF, HF, LF / HF), geometric indices (Poincaré plot, triangular interpolation of NN intervals (TINN) and triangular index (RRtri) and chaos domain indexes (Chaotic globals index and Higuchi Fractal Dimension). The evaluation of MS was made by 1maximum repetition, the body composition was evaluated by bioimpedance and BMI, and the cardiorespiratory parameters analyzed were blood pressure, heart rate and oxygen saturarion. The results showed that functional resistance training is better than conventional resistance training for benefits in AM promoting higher parasymphatetic action, although there were not differences on chaos domain among the groups. Just the functional group improved arterial blood pressure (ABP) when comparing pre and post training moments. However both training increased MS equally and none of the training programs promoted alterations on body composition. In conclusion, the functional resistance training is better than conventional resistance training to promote positive effect on AM and to reduce ABP, however both increased MS and did not change body composition in MetS individuals post 30 training sections.
