Multicomponent Exercise Program in Women With Hypertension

27. oktober 2026 opdateret af: Javier Fernando Rodríguez Triana, Universidad Pedagogica Nacional, Colombia

Effects of a Multicomponent Physical Exercise Program on Blood Pressure Parameters, Cardiorespiratory Capacity, Handgrip Strength and Quality of Life in Hypertensive Women With Cardiovascular Risk

This study tested whether a 12-week supervised multicomponent exercise program is associated with changes in blood pressure, estimated cardiorespiratory fitness, handgrip strength and health-related quality of life in women aged 45 to 59 years with hypertension. The program combined strength training, aerobic exercise (brisk walking or light jogging), controlled breathing and flexibility, in three sessions per week of about 60 minutes, mainly in community spaces in Bogotá, Colombia, with a hybrid option for women who could not attend in person. Thirty-two women were assigned, by convenience according to their availability for the class schedule, to an exercise group (n = 16) or to a control group that kept its usual activities (n = 16). Systolic and diastolic blood pressure, estimated cardiorespiratory fitness (Rockport 1-mile walk test), handgrip strength (dynamometer) and quality of life (SF-36 questionnaire) were measured before and after the 12 weeks.

Detaljeret beskrivelse

Design: non-randomized, parallel-group, quasi-experimental study with pre- and post-intervention measurements in an exercise group and a control group.

Recruitment and setting: participants were recruited in Bogotá, Colombia, during the two months before the baseline assessment (approximately from late April 2026), through an information session and written informed consent. The program was delivered mainly in community spaces in the Restrepo neighborhood (Antonio Nariño locality), with a hybrid option for participants who could not attend in person.

Timeline: baseline assessments were carried out on 24 and 26 June 2026 and the program started on 30 June 2026. Post-intervention assessments were carried out in week 12: blood pressure, handgrip strength and anthropometry on 17 September 2026 (about 48 hours after the last session), the Rockport walk test on 19 September 2026, and the SF-36 questionnaire was completed by participants between 17 and 19 September 2026.

Program: the exercise program followed the FITT-VP model (frequency, intensity, time, type, volume and progression), with progression in three phases (anatomical conditioning, development and consolidation). Exercise intensity was monitored with the OMNI perceived exertion scale (0-10), and heart rate was checked with a chest strap in a random subset of participants. In week 6, the exercise group completed tolerance check tests (blood pressure, cardiorespiratory fitness and handgrip strength) only to decide whether the plan needed adjustments; these were not part of the confirmatory analysis. The control group maintained its usual activities.

Analysis: the main analysis was a 2 x 2 mixed ANOVA (Group x Time), with the Group x Time interaction as the key parameter. An ANCOVA on post-intervention diastolic blood pressure, with baseline diastolic blood pressure as covariate, was added after a baseline imbalance was detected and was not specified in the original protocol.

REGISTRATION NOTE: this study was registered retrospectively, after data collection had been completed.

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Multicomponent exercise program

Supervised multicomponent exercise program for 12 weeks, three sessions per week (up to 60 minutes), combining strength training, aerobic exercise (brisk walking, rhythmic cardio-boxing and interval work), controlled breathing and flexibility. Program planned with the FITT-VP model and progressed in three phases (anatomical conditioning, development and consolidation). Delivered mainly in community spaces, with a hybrid option for participants who could not attend in person.

Supervised program of 12 weeks, three sessions per week (up to 60 minutes). Components: muscular strength training with elastic bands and body weight (squat, step-up, incline push-up, band row, farmer walk); aerobic exercise (brisk walking or jogging, rhythmic cardio-boxing and interval work at a prescribed intensity); controlled breathing (square breathing 4x4x4x4, diaphragmatic, pursed-lip and slow breathing) and flexibility (pectoral, hamstring, iliopsoas and lateral trunk stretches). Load progressed over three phases. Intensity was monitored with the OMNI perceived exertion scale (0-10) and, in a random subset of participants, with a chest-strap heart rate monitor (Polar H10).

Ingen indgriben: Control

Women with hypertension who maintained their usual activities during the 12 weeks and received no exercise program. They were assessed before and after the same period with the same instruments as the exercise group.

Tidsramme
Change in resting systolic blood pressure (SBP) from baseline to week 12
Tidsramme: Baseline (24 and 26 June 2026) and week 12 of the program (17 September 2026)

Resting systolic blood pressure in mmHg, measured with an automated upper-arm monitor (Omron HEM-716DT2). Three measurements at rest (at least 5 minutes of rest); the mean of the second and third measurements is used. Change = post-intervention value minus baseline value.

Tidsramme: Baseline (24 and 26 June 2026) and week 12 of the program (19 September 2026)

Estimated VO2 in ml/kg/min from the Rockport 1-mile (1,609 m) walk test, using walking time and final heart rate (recorded with a chest strap, Polar H10) in the equation of Kline et al. (1987). This is an estimate and not a direct measurement of maximal oxygen uptake. Change = post-intervention minus baseline.

Tidsramme: Baseline (June 2026) and week 12 of the program (completed between 17 and 19 September 2026)

SF-36 questionnaire, scored 0-100 for each of its eight domains (physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional and mental health); higher scores indicate better perceived health. Each domain was analyzed separately; no global SF-36 score was calculated. Change = post-intervention minus baseline.
