ABSTRACT=The present study aimed at investigating the effects of two different resistance training protocols — nonperiodized (NP) and daily undulating periodization (DUP) — on hemodynamic parameters of older women. Forty-two older women were randomized into one of the three experimental groups: NP, DUP, and control group (CG). Evaluations of the hemodynamic parameters occurred before, during and after six months. The exercise programs were performed twice a week over 22 weeks. NP and DUP groups were based on 3 sets of 8–10 repetitions in 9 exercises. In NP, the two exercise sessions were performed at a difficult intensity according to the rating of perceived exertion (RPE) method. In DUP, the first session was based on power resistance training, in which the concentric muscle contraction was performed as fast as possible at a moderate intensity based on RPE, while the second session was the same that was performed by NP. The findings demonstrated that diastolic blood pressure (90.4 mmHg vs 76.2 mmHg) and mean arterial pressure (108.6 mmHg vs 92.7 mmHg) was significantly reduced after NP, while no significant alterations were observed in DUP. Nevertheless, both training groups seem to have a cardioprotective effect, since heart rate values increased across the experimental period in CG. In conclusion, our findings indicate that a 22-week NP resistance training program causes beneficial effects on hemodynamic parameters of older women. Trial registration: NCT03443375.
