• topic: Post-exercise hypotension; Type 2 diabetes mellitus

Aim: To verify the occurrence of post-exercise hypotension (PEH) in type 2 diabetics (DM2) and the effects of exercise intensity on post-exercise blood pressure (BP). Methods: Eleven men and women with DM2 (58.5 10.2 years; 160 0.1 cm; 80.6 13.5 kg; 31.2 3.8 kg/m2, 19 3.2 mL kg min 1 of VO2 max, 155.0 39.2 mg dL 1 of fasting blood glucose and 126 10/75 7 mmHg of resting BP) performed an incremental test (IT) for cardiovascular evaluation and anaerobic threshold (AT) determination. Then, participants randomly underwent 2 exercise sessions (90% and 110% AT) and a control session (CON). In all sessions, BP was measured at resting, during 20 min of exercise/control and at each 15 min through 120 min of post-exercise recovery (R15–R120). Results: The mean results of systolic BP (SBP)/diastolic BP (DBP) over the 120 min of recovery were 125 16/76 7 mmHg, 122 13/75 6 mmHg and 129 16/78 7 mmHg, respectively for 90%, 110% and CON. Significant reductions of SBP occurred after 90% (R15–R45) and 110% (R15–R90), while only after 110% there were reductions of DBP (R15, R45) and MAP (R15, R45, R75, R90, R105). Conclusions: Both exercise intensities evoked reductions in SBP while DBP and MAP were reduced only after 110%. Despite the higher intensity exercise to be more effective in promoting BP reductions, we suggest caution while prescribing exercise for DM2.
