Exercise Periodization and Older Adults

University of Campinas, Brazil14 enrolled

Overview

The present study aimed at investigating the effects of two different resistance training protocols - nonperiodized (NP) and daily undulating periodization (DUP) - on hemodynamic, morphofunctional and cognitive parameters of robust older women. Methods: Forty-two older women were randomized allocated into one of the three experimental groups: NP, DUP, and control group (CG). Evaluations of the hemodynamic, morphofunctional and cognitive parameters occurred before, during and after six months. The exercise groups performed the program of exercise twice a week over 22 weeks. In NP, the two weekly sessions were based on 3 sets of 8-10 repetitions at a difficult intensity. However, in DUP, a power exercise session based on 3 sets of 8-10 repetitions at a moderate intensity was added in the first session of the week.
