Background: Few studies have investigated resistance training and its physiological and functional effects in the hypertensive elderly. Research question: The study aimed to analyse the effect of resistance training on resting blood pressure, body composition, muscular strength, functional capacity and blood variables in hypertensive elderly. Type of study: Randomised controlled study. Methods: Participants were 17 hypertensive elderly women divided into a training group (n = 7) and control group (n = 10). The training group performed a 12-week resistance training programme 3 d.wk-1, with the following exercises: bench press, leg extension, pull-down, leg curl, biceps curl, seated calf raise, pushdown and crunch. The control group performed 12 weeks of passive stretching training 2 d.wk-1. Body composition, maximal strength, resting blood pressure, blood variables and functional capacity were assessed before and after the training period. Results: There were significant changes (p<0.05) in muscular strength in the bench press exercise (28.6 ± 2.1 vs 32.6 ± 2.5 kg) and leg extension (22.7 ± 1.8 vs 26.3 ± 1.8 kg) and agility tests (6.0 ± 0.2 vs 4.6 ± 0.2 s), 10-m walk (6.5 ± 0.4 vs 5.5 ± 0.3 s) and lower limbs endurance (16.0 ± 1.0 vs 18.7 ± 1.8 rps). Also, the training group showed lower values (p<0.05) than the control group in triglycerides (79.5 ± 13.6 vs 137.3 ± 17.8 mg.dL-1) and blood glucose (85.2 ± 1.9 vs 95.0 ± 2.8 mg.dL-1) at post-training. No significant changes were identified in resting blood pressure and body composition. Conclusion: Twelve weeks of resistance training were sufficient to increase muscle strength and functional capacity of hypertensive elderly, but without statistically modifying the values of resting blood pressure, body composition and blood variables.
