Impacto de un programa de promoción de actividad física en mujeres trabajadoras de dos empresas de Bogotá

Estilos de vida activos y saludables se han asociado con mejoras en calidad de vida de mujeres trabajadoras. Objetivos: establecer la efectividad de un programa de actividad física para mejorar componentes del fitness en mujeres trabajadoras de dos empresas de Bogotá. Materiales y métodos: se realizó un estudio longitudinal, descriptivo de carácter exploratorio, con mediciones previas y posteriores de variables cuantitativas de componentes del fitness. Se incluyeron mujeres trabajadorasde 24 a 49 años, sin factores de riesgos asociados y sin restricciones para la práctica de actividad física de acuerdo con el cuestionario PARQ & YOU. Quince mujeres (37,33 ±9,3) se sometieron voluntariamente a la intervención en actividad física durante un período de 12 semanas, 60 minutos diarios. Para el análisis estadístico de los datos, se empleó el paquete estadístico SPSS 17. Resultados: se presentaron cambios significativos después de la intervención en el índice de masa corporal (IMC) (p = 0,023), resistencia abdominal (p = 0,004) y fuerza en miembros inferiores (MMII) (p = 0,001). No hubo cambios estadísticamente significativos en consumo pico de oxígeno y flexibilidad. Conclusión: a partir de estos resultados, se pudo establecer que el protocolo del programa de promoción de actividad física aplicado produjo cambios en el fitness de las mujeres que lo completaron, lo que significa que este puede ser replicado con resultados efectivos tras su desarrollo.

Pedometer: intervention strategy and physical activity promotion

World Health Organization (WHO) has prioritized physical activity (PA) as one of the mostrelevant strategies leading the decreasing prevalence of noncommunicable chronic diseases. Pedometer has emerged as one of the valid intervention programs, reliable and useful to assess,measure and promote the physical activity practice, through counts the number of steps perday. One of the aims is to establish the goals based on steps per day made by a person and thepositive feedback, which can generate behavior changes and adoption of healthy habits, from a regular physical activity practice perspective. This review attends to enhance the current state ofpedometer program, as an intervention one, in all kind of population; its health impact and theapplication methodologies, using the pedometer as a steps quantifier device, with feasible access,use and management. Additionally, the review will be useful as a framework to design futureresearch projects, aim to develop, adapt and apply evidence based pedometer protocols, insideclinical, academic and community context.

Implementation of ‘School Back’ by the ‘Core’ technique in a factory of geotextiles to prevent back pain

Introduction: This article aims to show an alternative intervention for the prevention and control of back pain to the people of a production plant of geotextiles for the construction exposed to handling and awkward postures through the implementation of the Back School using the CORE technique. This technique being understood as trainer of the stability musculature of the spine; whose benefit is proportionate the muscular complex of the back, stability and avoid osteomuscular lesions and improved posture. Objective: To present the results about the implementation of the back school by the CORE technique for prevention of back pain in a population of forty-eight male collaborators. Materials and methods: The back school began with talks of awareness by the occupational health physician explaining the objectives and benefits of it to all participants. Once this activity was done, was continued to evaluate all plant employees to establish health status through the PAR-Q questionnaire, who were surveyed for the perception of pain using visual analog scale (VAS) and stability was determined column through the CORE assessment, to determine the training plan. Then, were made every six months the revaluations and implementation of a survey of assistant public perception to identify the impact of the implementation of the school back on the two variables referred (pain perception and stability of column). Results: The pain perception according VAS increased in the number of workers asymptomatic in 12% and based in the satisfaction survey 94% of population reported that with the development of this technique decrease the muscle fatigue in lumbar level; and 96% of population reported an improvement in the performance of their work activities. Discussion: Posterior to the analysis of all results, it is interpreted that back schools practice through CORE technique, contributes to the prevention and / or control of symptoms at the lumbar level in population of productive sector exposed to risks derived from the physical load, provided that ensure its continuously development and supervised for a competent professional.
