Brief Summary

The purpose of the present study was to analyze the effect of 12 weeks of resistance training on post-exercise blood pressure (BP) and to to correlate the acute and chronic decrease in blood pressure (BP) following resistance training in normotensive older women. Twenty-eight older women were randomly assigned to a training group (TG) or to a control group (CG). The TG underwent a resistance training program (8 exercises, 2 sets, 10-15 repetitions), while the CG performed stretching exercises (2 sets, 20 s each, 2 nonconsecutive days/week). Both groups performed the intervention for 12 weeks. At baseline and after intervention the subjects were submitted to two sessions: resistance exercise session and control session. In these sessions, BP was obtained in pre and post-sessions. Rest blood pressure were also measure at baseline and after 12 weeks of intervention.

Intervention gruop

EXPERIMENTAL

The intervention group was submitted to a resistance training program that consisted of eight exercises performed in two sets of 10 to 15 repetitions, three times per week.

Behavioral: Resistance training

Control group

NO INTERVENTION

The control group performed a stretching training program for the major muscle groups, in sessions of 30 minutes, twice a week

Interventions

Resistance training BEHAVIORAL

Supervised resistance training program was performed on three nonconsecutive days per week at morning period for 12 weeks. The resistance training program included eight exercises in two consecutive sets of 10-15 repetitions until moderate fatigue, except for crunch exercise which was performed on 20 to 30 repetitions without overload. The participants were instructed to perform repetitions at a ratio of 1:2 (concentric and eccentric phases, respectively). Subjects rested for 60- to 90-s between each set and for 2- to 3-min between each exercise. Each subject was individually supervised. Increases of 2-5 % for the upper limb exercises and 5-10 % for the lower limb exercises every time that subjects were able to complete 15 repetitions in both sets.
