Objetivo Evaluar los efectos de un programa recreativo de actividad física general, de intensidad moderada y corta duración, sobre las cifras de hipertensión arterial y otros factores de riesgo cardiovascular (FRCV) en hipertensos mayores de 50años.
Diseño Estudio cuasi-experimental no aleatorizado con diseño pre-post.
Emplazamiento Íllora (Granada).
Participantes Sesenta sujetos sedentarios de 50-75años pertenecientes al programa de hipertensos del Centro de Salud.
Intervención Programa lúdico de actividad física general donde predomina la capacidad aeróbica, 3días/semana, durante 4 semanas, y una intensidad del 45-55% de la FC Reserva.
Mediciones principales PAS, PAD, FC, IMC, colesterol total, HDL, LDL, TG y glucosa.
Resultados y conclusiones Disminuciones estadísticamente significativas (p<0,05) en el IMC (−0,51%; IC95%: 30,26-31,93unid), la FC (−5,57 lat/min; IC95%: 68,76-71,73lat/min), la PAS (−14,82mmHg; IC95%: 131,57-137,52mmHg), la PAD (−5,33mmHg; IC95%: 78,94-83,68mmHg), la glucosa (−7,63mg/dl; IC95%: 125,06-153,73mg/dl) y el riesgo REGICOR (−20,46%; IC95%: 5,45-6,90%).
Aumentos estadísticamente significativos en el HDL (+2,82mg/dl; IC95%: 46,78-52,11mg/dl) y los TG (+8,27mg/dl; IC95% 133,89-152,60mg/dl).
Según el sexo, los hombres presentaron la mayor variación en la FC y la PAD, y las mujeres en la PAS (p<0,05). Sujetos con valores iniciales de PAS≥160mmHg experimentaron mayores descensos de FC, PAS, PAD, glucosa y TG (−10,67lat/min, −31mmHg, −8,27mmHg, −10,86mg/dl y 34,66mg/dl, respectivamente) que aquellos con PAS inicial <160mmHg, donde aumentó el HDL y disminuyó el LDL.
Tras este programa se obtuvieron mejoras en la presión arterial y otros FRCV en sujetos hipertensos mayores de 50años.
Objectives To evaluate the effects of a recreational general physical activity program with moderate intensity and short duration on blood pressure and other cardiovascular risk factors (BMI, cholesterol, Rest Heart Rate, HDL, LDL, Triglycerides) in hypertensive patients older than 50years.
Design Non-randomised pre-post design, quasi-experimental study.
Location Íllora, Granada, Spain.
Participants A total of 60 subjects aged 50-75years taking part in the Health Hypertensive Program in the Medical Centre were selected.
Intervention A recreational general physical activity program, mainly aerobic capacity, of 4weeks duration, 3days/week, and an intensity of 45-55% HR Reserve.
Main measurements SBP, DBP, HR, BMI, total cholesterol, HDL, LDL, TG, and Glucose.
Results and conclusions Statistically significant decreases (P<.05) were observed in BMI (−0.51%; 95%CI: 30.26 to 31.93units), HR (−5.57beats/min; 95%CI: 68.76 to 71.73beats/min), SBP (−14.82mmHg; 95%CI: 131.57 to 137.52mmHg), DBP (−5.33mmHg; 95%CI: 78.94 to 83.68mmHg), Glucose (−7.63mg/dL; 95%CI: 125.06 to 153.73mg/dL) and REGICOR risk (−20.46%; 95%CI: 5.45 to 6.90%).
Statistically significant increases were observed in HDL (+2.82mg/dl; 95%CI: 46.78 to 52.11mmHg), and TG (+8.27mg/dl; 95%CI: 133.89 to 152.60mg/dL).
Men had a wider variation in HR and DBP, and women in SBP (P<.05). Subjects with baseline SBP≥160mmHg experienced greater declines in HR, SBP, DBP, Glucose and TG (−10.67beats/min, −31mmHg, −8.27mmHg, −10.86mg/dL, and 34.66mg/dL, respectively) than those with an initial SBP<160mmHg, where there was an increase in HDL and a decrease in LDL.
After this program, improvements in BP and other cardiovascular risk factors were obtained in hypertensive subjects over 50years.
