Brief Summary

Introduction: Strength training (ST) is an important non-pharmacological means to reduce blood pressure (BP). Objective: To verify the pressure response of women after 8 weeks of ST. Method: Fourteen women were divided into young group (YG) and middle age (MAG) and submitted to ST for 8 weeks, lasting 60 minutes in 11 alternating exercises per segment with intensity of 12 to 13 on the subjective perception scale of effort. BP was verified at weeks 1, 4 and 8.

Blood Pressure; Resistance Training; Women

Outcome Measures

Primary Outcomes (2)

• Blood pressure

  Increased blood pressure in young group and reduced blood pressure in middle age group

  Four weeks

• Blood pressure

  Increased blood pressure in young group and reduced blood pressure in middle age group

  Eight weeks

Study Arms (2)

Young Group

EXPERIMENTAL

Young women who underwent 8 weeks of training and had their blood pressure checked at baseline and after 4 and 8 weeks of training. Resistance training sessions were held 3 times a week, in which each session lasted 60 minutes and was performed for a period of 8 weeks. Each session consisted of 10-minute warm-up, shortly after, starting the exercises in the form of alternating circuit by segment, as: machine bench press, extension chair, high pull (front), flexor table, direct curl, leg press, triceps pulley, adductor, abdominal, abductor and calf. In all 10 exercises, 3 sets of 8 to 12 repetitions were performed, with an interval of 60 seconds between sets and intensity of 12 arbitrary units (a.u.) to 14 a.u., measured by the rate perception effort scale.

Other: Resistance trainining

Middle-aged Group

EXPERIMENTAL

Middle-aged women women who underwent 8 weeks of training and had their blood pressure checked at baseline and after 4 and 8 weeks of training. Resistance training sessions were held 3 times a week, in which each session lasted 60 minutes and was performed for a period of 8 weeks. Each session consisted of 10-minute warm-up, shortly after, starting the exercises in the form of alternating circuit by segment, as: machine bench press, extension chair, high pull (front), flexor table, direct curl, leg press, triceps pulley, adductor, abdominal, abductor and calf. In all 10 exercises, 3 sets of 8 to 12 repetitions were performed, with an interval of 60 seconds between sets and intensity of 12 arbitrary units (a.u.) to 14 a.u., measured by the rate perception effort scale.

In the first, fourth and eighth week, pre-exercise blood pressure (BP) was verified, in which the participants sat for a period of 10 minutes at rest, in a comfortable chair, with legs uncrossed, feet flat on the floor, back leaning on the chair, left arm at heart level and palm up to measure BP using a G \* Tech-branded automatic digital device (MASTER model).
