[Purpose] To verify the effects of different intensities of aerobic exercise on 24-hour ambulatory blood pressure (BP) responses in individuals with type 2 diabetes mellitus (T2D) and prehypertension. [Subjects and Methods] Ten individuals with T2D and prehypertension (55.8 +/- 7.7 years old; blood glucose 133.0 +/- 36.7 mg.dL(-1) and awake BP 130.6 +/- 1.6/80.5 +/- 1.8 mmHg) completed three randomly assigned experiments: non-exercise control (CON) and exercise at moderate (MOD) and maximal (MAX) intensities. Heart rate (HR), BP, blood lactate concentrations ([Lac]), oxygen uptake (VO2), and rate of perceived exertion (RPE) were measured at rest, during the experimental sessions, and during the 60 min recovery period. After this period, ambulatory blood pressure was monitored for 24 h. [Results] The results indicate that [Lac] (MAX: 6.7 +/- 2.0 vs. MOD: 3.8 +/- 1.2 mM), RPE (MAX: 19 +/- 1.3 vs. MOD: 11 +/- 2.3) and VO(2)peak (MAX: 20.2 +/- 4.1 vs. MOD: 14.0 +/- 3.0 mL . kg(-1).min(-1)) were highest following the MAX session. Compared with CON, only MAX elicited post-exercise BP reduction that lasted for 8 h after exercise and during sleep. [Conclusion] A single session of aerobic exercise resulted in 24 h BP reductions in individuals with T2D, especially while sleeping, and this reduction seems to be dependent on the intensity of the exercise performed.
