Purpose: To investigate the blood pressure responses during recovery after two protocols of circuit resistance exercises (CRE) with different rest intervals (RI). Methods : Eleven normotensive males (aged 19.5 ± 1.0 yrs, height 172.8 ± 5.7 cm and weight 65.1 ± 8.1 kg) performed two CRE with RI of 30 (RI30s) and 40 (RI40s) seconds between the exercises randomly, as well as a control session without exercise. The protocols consisted of 3 circuits of 6 exercises with 10 repetitions maximum (10RM) and 2 minute rest between circuits, followed by an 80 minute recovery period. Measurements were taken before exercise and at each 10 min of post-exercise recovery. The Analysis of Variance (ANOVA) with Repeated Measures (group × time) was used to analyze data, followed by post-hoc Bonferroni test, for P ≤0.05. Results : Post- exercise hypotension of systolic blood pressure was observed after both CRE with RI30s and RI40s (at R40, R50, R60, R70 and R80) , whereas diastolic blood pressure did not differ from that measured at rest. In all measured moments, there was no significant difference between exercise trials in post-exercise levels of SBP and DBP. Conclusion : CRE with RI30s and RI40s between the exercises can lead to occurrence of PEH similarly in magnitude and duration. Our findings suggest a potentially positive health benefit of strength training. Key Words: Post-exercise Hypotension; Resistance Exercise; Systolic Blood Pressure; Diastolic Blood Pressure |
