ABSTRACT
This study analyzed the postexercise blood pressure (BP) after resistance exercise (RE) on middle-aged type-2 diabetic (T2DM, n = 10, 46.6 +/- 13.1 years) and nondiabetic subjects (NDM, n = 10, 52.0 +/- 13.2 years). Participants performed (a) 1 repetition maximum (1RM) strength test; (b) 3 laps in an RE circuit of 6 exercises (16 repetitions at 43% 1RM); (c) 3 laps in an RE circuit (30 repetitions at 23% 1RM); and (d) a control session. The blood lactate concentration ([lac]) (YSI 2700S) and BP (Microlife BP3AC1-1) were measured pre-exercise, after exercise, and at each 15 minutes during the 120 minutes of recovery. Analysis of variance with Bonferroni as a post hoc evidenced that the 43% 1RM session elicited the highest [lac] response for both NDM (7.8 +/- 1.8 vs. 6.4 +/- 1.8 mmol x L(-1); p < 0.05) and T2DM (7.0 +/- 1.4 vs. 5.6 +/- 1.6 mmol x L(-1); p < 0.05). Also, the 43% 1RM session promoted a significant postexercise hypotension (PEH) of systolic blood pressure (SBP) and mean arterial pressure (MAP), whereas the 23% 1RM did not. The highest BP reductions for T2DM and NDM after 43% 1RM were, respectively, 9.5 +/- 11.1 and 11.0 +/- 7.1 mmHg for SBP and 6.4 +/- 7.8 and 7.7 +/- 7.9 mmHg for the MAP (p
