Abstract
Objetivo
Analizar la influencia de un programa de ejercicio físico de fuerza/resistencia sobre los factores de riesgo cardiovascular en mujeres posmenopáusicas de bajo riesgo.
Diseño
Ensayo clínico aleatorizado de 6 meses de duración.
Emplazamiento
El estudio se realizó en 3 centros de salud de la Comunidad Autónoma de Murcia.
Participantes
Participaron en el estudio 63 mujeres posmenopáusicas de 45-59 años con riesgo cardiovascular bajo.
Intervenciones y mediciones principales
Las mujeres participantes fueron divididas en 2 grupos: a) control, sin intervención específica (n = 23), y b) intervención mediante ejercicio de fuerza/resistencia con protocolo en medio acuático y terrestre (n = 40). A todos los grupos en la visita inicial y final se les realizaron anamnesis, exploración física y analítica general incluyendo Apo A, Apo B, insulina, creatinina sérica, aclaramiento de creatinina, creatinina en orina, albuminuria, proteína C reactiva ultrasensible e índice HOMA.
Resultados
Los valores de insulina aumentan en el grupo control 2,02 mU/l y descienden en el grupo experimental 0,13 mU/l (p = 0,021). Al inicio del estudio la creatinina en el grupo control es de 0,83 ± 0,12 mg/dl, y de 0,91 ± 0,02 mg/dl al final del estudio. En el grupo de intervención es de 0,84 ± 0,12 mg/dl al inicio del estudio, y de 0,90 ± 0,13 mg/dl al final (NS). La presión arterial sistólica disminuye en ambos grupos, y es mayor el descenso en el grupo de ejercicio (11,81 frente a 0,17 mmHg); (p = 0,0001). Los valores de colesterol unido a lipoproteínas de alta densidad aumentan en el grupo control (4,97 mg/dl) y en el grupo experimental (3,46 mg/dl) (NS).
Conclusiones
Un programa controlado de ejercicio físico de fuerza/resistencia en la mujer posmenopáusica disminuye su riesgo cardiovascular.

Abstract
Objective
To analyse the influence of a physical exercise programme of strength/stamina on cardiovascular risk factors in low-riskpost-menopausal women.
Design
Six-month randomised clinical trial with post-menopausal women.
Setting
Three health centres in the autonomous community of Murcia, Spain.
Participants
Sixty-three post-menopausal women aged 45 to 59 at low cardiovascular risk.
Interventions and main measurements
They were split into 2 groups: a) control: 23 people with no specific intervention, and b) 40 people with an intervention of strength/stamina exercise with protocol for in water and on land. At their initial and final visits, everyone in the 2 groups had anamnesis, physical examination, and general analyses, including Apo A, Apo B, insulin, serum creatinine, creatinine clearance, creatinine in urine, albuminuria, ultrasensitive PCR, and HOMA index.
Results
The insulin levels increased in the control group by 2.02 mU/L and dropped in the experimental group by 0.13 mU/L (P=.021). Atthe start ofthe study, creatinine in the control group was 0.83±0.12 mg/dL; and atthe end, 0.91±0.02 mg/dL. In the intervention group it was 0.84±0.12 mg/dL at the start and 0.90±0.13 mg/dL atthe end (NS). Systolic blood pressure dropped in both groups, with a bigger drop in the exercise group (11.81 vs 0.17 mm Hg) (P=.0001). HDL-C values increased in the control group by 4.97 mg/dL; and in the experimental group, by 3.46 mg/dL (NS).
Conclusions
A controlled programme of strength/stamina physical exercise reduces the cardiovascular risk of post-menopausal women.
