Resumen
- English
Resistance Training (RT) has been considered capable of promoting improvements in cardiovascular parameters in a safe way. The double-product (DP) is the main indicator of the cardiovascular intensity of the RT and is associated with myocardial oxygen consumption, being therefore a valid parameter for the control of cardiovascular risks. The purpose of this study was to investigate the effects of the RT of metabolic and tensional characteristics in acute cardiovascular responses. The study analyzed two sessions of RT, one of metabolic characteristic and the other one of tensional characteristic, leg press exercises, extensor chair and flexor chair, in relation to the behavior of PD in 10 women (age = 27.1 ± 6 years, mass = 62.5 ± 5 kg, height: 1.63 ± 0.05 m), with one year of resistance training. No significant difference was found between the cardiovascular variables assessed at the end of both modalities of resistance training. However, diastolic BP was higher in the tensional modality during the leg press (p = 0.006), whereas systolic BP was lower in this modality during the extensor chair (p = 0.005). While the double-product between the leg press and the extensor chair was more notable in the tensional modality (p = 0.004) and that the variation of the heart rate in relation to rest was superior in the metabolic modality (p = 0.041). The study concludes that both training methods present similar cardiovascular responses and that the load percentage does not seem to interfere in these aspects, but intervals of series, exercises with greater muscle recruitment.

O Treinamento Resistido (TR) tem sido considerado capaz de promover melhoras em parâmetros cardiovasculares de maneira segura. O Duplo-Produto (DP) é o principal indicador de intensidade cardiovascular do TR e está associado consumo de oxigênio do miocárdio, sendo assim, é um parâmetro válido para o controle de riscos cardiovasculares. O propósito deste trabalho é investigar os efeitos do TR de característica metabólica e tensional nas respostas cardiovasculares agudas. O estudo analisou duas sessões de TR sendo uma de característica metabólica e a outra de característica tensional, os exercícios leg press, cadeira extensora e cadeira flexora, em relação ao comportamento do DP, em 10 mulheres (idade= 27,1±6 anos; massa= 62,5±5 kg; estatura: 1,63±0,05m), com um ano de treinamento resistido. Não foi encontrada diferença significante entre as variáveis cardiovasculares aferidas ao fim de ambas as modalidades de treino resistido. Entretanto a PA diastólica apresentou-se maior na modalidade tensional durante o leg press (p=0,006), enquanto que a PA sistólica se apresentou inferior nesta modalidade durante a cadeira extensora (p=0,005). Enquanto o duplo-produto entre o leg press e a cadeira extensora foi mais notável na modalidade tensional (p = 0,004) e que a variação da frequência cardíaca em relação ao repouso foi superior na modalidade metabólica (p= 0,041). O estudo conclui que ambos os métodos de treinamento apresentam respostas cardiovasculares similares e que o percentual de carga não parece interferir nesses aspectos e sim intervalos de séries, exercícios com maior recrutamento muscular.
