Different orders of exercises during the circuit method does not alter the hemodynamic responses - Pilot Study

Abstract

Introduction: The effect of Circuit Training (CT) order’s on hemodynamics variables is inconclusive. Objective: To evaluate the effect of different orders of execution in acute hemodynamic responses in the CT. Methods: Eleven men were recruited. Training sessions were composed by the following sequence: Sequence A: multi-joint/single-joint; Sequence B: single-joint/multi-joint, performed at 60% of 1-MR with one minute interval. Both circuits were composed of three passes with eight stations. The outcomes were: systolic blood pressure (BPS), diastolic (DPS), heart rate (HR) and double product (DP). For comparisons was used two-way ANOVA repeated measures considering p<0.05. Results: HR values ​​were significantly higher during and after exercise compared to baseline, increase of DP (p< 0,001) and decrease of BPS (p<0,001) after practice, regardless of the order of exercise execution. Conclusion: The CT method is efficient in promoting the hypotensive effect post-exercise regardless of the order of execution.
