Abstract
Background: The effect of resistance training (RT) on the behavior of blood pressure (BP), heart rate (HR) and double product (DP) is strongly related to the characteristics of exercise and is inconsistent with hypertensive individuals. Objectives: To compare the acute and late cardiovascular response in sessions of 50% and 75% of maximum estimated repetition in grade-1 hypertensive individuals. Methods: For 24 hours, the study analyzed systolic blood pressure (SBP) and diastolic blood pressure (DBP) in 14 mild hypertensive men, trained (TG) and untrained (UG), under protocols of 75% and 50% on maximum estimated repetition. The level of cardiovascular stress in eight exercises for the two intensities mentioned was concomitantly observed. Results: In the TG, the variable SBP showed differences between the protocol of lower intensity compared to the other, 50% with control (p=0.028) and 50% to 75% (p=0.022), and DBP differed only in the protocols of 50% with control (p=0.024). In the UG, the difference occurred in all protocols, as well in SBP [50% and control (p=<0.0001); 75% and control (p=0.039); and 50% and 75% (p=0.001)] as in DBP [50% and control (p=0.002); 75% and control (p=0.002); and 50% and 75% (p=0.002)]. On cardiovascular stress, the exercises seated row, leg press in the TG and high row, leg curl and abdominal crunch in the UG differed in both protocols. Conclusion: The results indicate safety in RT in mild hypertension men. It became evident that the lower intensity protocol showed higher efficiency in promoting post-exercise hypotension.
Highlights
Resistance training (RT) enables the reduction of postworkout blood pressure, post-exercise hypotension (PEH) in normotensive individuals and especially in hypertensive individuals[1,2]; there are discrepancies when specifying the influence of intensity in that response in hypertensive individuals.During the resistance training (RT), response of hemodynamic variables, heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) are dependent on variables of such training mode: load, training volume, tension time, muscle mass mobilized, interval between sets and interval between exercises[3,4,5]
This behavior of matching SBP levels can possibly be assigned to the interdependent behavior of the variables HR, systolic volume (SV) and peripheral vascular resistance (PVR), because the cardiac output (CO) is the product of HR by SV, and SBP is the product of CO by PVR
It is concluded that the RT is safe from the cardiovascular point of view for individuals with mild hypertension
