Bertani, RF, Campos, GO, Perseguin, DM, Bonardi, JMT, Ferriolli, E, Moriguti, JC, and Lima, NKC. Resistance exercise training is more effective than interval aerobic training in reducing blood pressure during sleep in hypertensive elderly patients. J Strength Cond Res 32(7): 2085–2090, 2018—An appropriate fall in blood pressure (BP) during sleep is known to be related to a lower cardiovascular risk. The objective of this study was to compare the effect of different types of training on hypertensive elderly patients under treatment in terms of pressure variability assessed by the nocturnal decline in BP. Hypertensive elderly subjects under pharmacological treatment were randomly assigned to the following groups: 12 weeks of continuous aerobic training, interval aerobic training (IA), resistance training (R), or control (C). All subjects underwent ambulatory BP monitoring before and 24 hours after the last exercise session. The results were assessed using the mixed effects model. A greater nocturnal decline in diastolic BP compared with the wakefulness period was observed in R in comparison with C (11.0 ± 4.1 vs. 6.0 ± 5.7 mm Hg and p = 0.01) and with IA (11.0 ± 4. vs. 6.5 ± 5.1 mm Hg and p = 0.02). No fall in BP during a 24-hour period was observed in training groups compared with C, perhaps because the subjects were mostly nondippers, for whom the effect of training on BP is found to be lower. In conclusion, resistance training promoted a greater nocturnal fall in BP among hypertensive elderly subjects under treatment compared with IA subjects.
