JEPonline 2012;15(1):98-109. Different exercise modes have been suggested as non-pharmacological treatment for the prevention and/or control of elevated blood pressure and glycemia. Therefore, with objective of the analyze the occurrence of postexercise hypotension (PEH) to aerobic (AE) and resistance exercises (RE) in type-2 diabetics, nine type 2 diabetics performed: 1) 20-min of cycling (AE) at lactate threshold intensity; 2) RE at 70% of 1RM; and 3) control session (CONT). Heart rate (HR), blood pressure (BP), blood lactate ([lac]), oxygen consumption (VO2) and rate of perceived exertion (RPE) were measured at rest, exercise or CONT and postsession recovery. Mean VO2 (mL·kg-1 ·min-1) of RE (10.6 ± 1.7) was lower than AE (13.3 ± 1.4) (P<0.05). VO2 peak measured immediately after each RE bout (17.5 ± 3.4) was higher than in AE (P<0.05). The RE but not AE elicited PEH (P<0.05). The mean arterial pressure decrease after 1 hr of recovery in RE by ~5.3 mmHg, while AE elicited a non-significant decrease of ~1.9 mmHg. Only the 70% of 1RM RE circuit training model promoted PEH in type 2 diabetic individuals, perhaps, due to the higher cardiovascular and metabolic stress when compared to the AE session.
