Ambulatory blood pressure monitoring in normotensive individuals undergoing two single exercise sessions: resistive exercise training and aerobic exercise training.
OBJECTIVE
To assess the influence of 2 single exercise sessions on blood pressure in sedentary normotensive individuals: one of resistive exercise training (circuit weight training) and the other of aerobic exercise training.


METHODS
Using ambulatory blood pressure monitoring, this study assessed 25 individuals as follows: in a controlled situation at rest (ABPM 1); after resistive exercise training (ABPM 2); and after aerobic exercise training (ABPM 3). Resistive exercise training was performed as circuit weight training with an intensity of 40% of each individual's maximum strength. The aerobic exercise training was performed on a cycloergometer with intensity between 60% and 70% of the maximum heart rate (HR) reached during previous exercise testing.


RESULTS
Systolic blood pressure (SBP) values during 24 hours and during subperiods of wakefulness and sleep showed no statistically significant variations when the results obtained at rest were compared with those of ABPM2 and ABPM3, and when the results of ABPM2 were compared with those of ABPM3. The mean heart rate during 24 hours and in the wakefulness period showed significant increases (P<0.05), when ABPM2 was compared with ABPM3.


CONCLUSIONS
A single session of resistive exercise training in normotensive individuals was sufficient to cause significant reductions in blood pressure levels after exercise in the period of sleep. The session of aerobic exercise training in these same individuals was more effective in significantly reducing blood pressure levels.
