Acute effects of isometric sets combination with dynamic in hemodynamic aspects

Abstract

Introduction: The objective was to verify the hemodynamic responses during the combination of isometric sets with dynamic sets until exhaustion in squat. Methods: Fourteen trained women was performed anthropometry and identification load of 1RM in squat. After, it was performed the Isometrico+Dynamic Protocol with one maximum isometric sets of 20 seconds and three dynamic sets 80% of 1RM until exhaustion, measuring heart rate, systolic and diastolic blood pressure, at rest (pre), isometry and dynamic (post). Then, it was performed only the dynamic execution in Dynamic Protocol, measuring the same variables at rest (pre) and dynamic (post). Results: No significant differences were found between protocols in variables and intragroup analysis of Isometrico-Dynamic Protocol identified summative acute increase in heart rate, systolic and diastolic blood pressure and product double (p<0,05). Conclusions: One isometric sets the prior dynamic sets cause summative acute increase in hemodynamic responses, without significant changes between the two protocols.
