Acute and chronic effects of muscle power training on blood pressure in elderly patients with type 2 diabetes mellitus

Abstract

The aim of the present study was to evaluate the effects of 12 weeks of muscle power training (MPT) on casual blood pressure (BP) (before and after each training session) and resting BP (pre-and post-training program) in type 2 diabetes mellitus (T2DM) elderly. Methods: Twelve T2DM elderly individuals (68.75 ± 7.83 years), non-insulin-dependents participated in the present study and performed the MPT program twice a week. Casual BP was measured before and after training sessions, and resting BP was measured 48 h before the first and 48 h after the last training session. Results: Significant decrease in casual systolic (SBP) (−7.08 ± 4.12 mm Hg [effect size [ES]: −1.42 to −0.11]; p < 0.01) and diastolic (DBP) BP (−3.14 ± 1.24 mm Hg [ES: −1.24 to −0.18]; p > 0.01) was found after training sessions, without significant effect (p > 0.05) of the week along time or casual BP × week interaction. No significant change in resting SBP (−5.08 ± 8.93 mm Hg [ES: −0.41]; p = 0.07) and DBP (0.47 ± 6.06 mm Hg [ES: +0.11]; p = 0.79) was found. Conclusion: MPT was able to reduce casual BP after training sessions. However, there was no significant reduction in resting BP after MPT. Nevertheless, although not statistically significant, there were important clinical reductions in resting SBP in T2DM elderly patients.

Effect of High-velocity Resistance Exercise on 24-h Blood Pressure in Hypertensive Older Women

“…Different from previous studies that have assessed BP post-exercise during a very short-term period in a laboratory setting [10,11,25], the present study showed in a sample of hypertensive older women that a HVRE session elicited a systolic PEH up to 4 h post-exercise in free-living conditions. This BP reduction observed in the present investigation may have attenuated the overload imposed to the subjects' cardiovascular system during their daily activities, which is clinically meaningful.…”

“…No changes were observed for BP, despite a lower HR and an increased NO bioavailability 30 min post-exercise. Although discrepancies exist among the investigations, the present results and others [11,25] suggest that a power exercise or HVRE session elicits PEH in hypertensive older adults.…”

“…Similar to the present findings, following the power exercise session there was a reduction in systolic BP lasting up to 45 min post-exercise, which was accompanied by a higher NO bioavailability up to 60 min post-exercise. Machado et al [25] reported a systematic occurrence of PEH following power exercise sessions performed over a 12-week period of a power training intervention in older women with type 2 diabetes. On the contrary, no PEH following a single power-exercise session was observed by Orsano et al [10], who compared traditional resistance exercises and power exercises using weight-training equipment up to 45 min post-exercise.…”

Saffron (Crocus sativus L.) in combination with resistance training reduced blood pressure in the elderly hypertensive men: A randomized controlled trial

“…week with moderate intensity. 43 After 20 weeks of high-intensity RT with a frequency of 2 sessions per week, the central SBP and DBP were significantly reduced by 6 and 3 mmHg, respectively, in healthy men and women. Brachial BP also showed a significant reduction.…”

“…Significant changes in resting SBP and DBP were not observed in the elderly with diabetes mellitus 48 hours after the last session of 12 weeks of RT. Exercises were performed twice a week with moderate intensity 43 . After 20 weeks of high‐intensity RT with a frequency of 2 sessions per week, the central SBP and DBP were significantly reduced by 6 and 3 mmHg, respectively, in healthy men and women.…”
