Efeito hipotensivo no treinamento resistido: influência da massa muscular envolvida

Introducao: A massa muscular (MM) solicitada durante o exercicio resistido (ER) exerce influencia nas respostas cardiovasculares. Objetivo: Comparar o efeito da MM nas respostas cardiovasculares durante e apos o ER. Metodos: Onze sujeitos normotensos (22,2 ± 2,8 anos; 171,2 ± 9,4 cm; 68,0 ± 12,6 kg) foram submetidos, em diferentes dias, aos exercicios: supino reto (SR) e voador (VOA). As medidas da pressao arterial (PA), frequencia cardiaca (FC) e duplo produto (DP) foram feitas no repouso, final do exercicio e durante 60 minutos pos-exercicio. Resultados: Ambos os exercicios proporcionaram aumento da PA, FC e DP em relacao ao repouso (p Introduction: Muscle mass (MM) requested during resistance exercise (RE) influences on cardiovascular responses. Objective: To compare the effect of MM on cardiovascular responses during and after the ER. Methods: Eleven normotensive subjects (22.2 ± 2.8 years; 171.2 ± 9.4 cm; 68.0 ± 12.6 kg) were submitted, on different days, to the follow exercises: bench press (SR) and albacore (VOA). Measurements of blood pressure (BP), heart rate (HR) and double product (DP) were made at rest, immediately after exercising, and during 60 minutes post- exercise. Results: Both exercises caused increased BP, HR and DP compared to rest (p
