Physical exercise reduces occupational and oxidative stress in Emergency Department staff

Abstract

[ES]: [Fundamento]: Situaciones estresantes conducen a la formación de un exceso de radicales libres, que constituyen la mayor amenaza para la homeostasis celular de organismos aerobios. El burnout es un síndrome de estrés crónico laboral. [Objetivos]: 1. Determinar tanto el estrés oxidativo como el estrés laboral al que se encuentran sometidos profesionales sanitarios de un servicio de urgencias. 2. Analizar la influencia que la práctica de ejercicio físico puede ejercer tanto sobre el estrés oxidativo como sobre el estrés laboral de estos profesionales. [Material y métodos]: Se han analizado 70 profesionales de un servicio de urgencias hospitalarias y un grupo control de 80 individuos sanos y edades similares. En todos se determinó la actividad de superóxido dismutasa (SOD) y catalasa (CAT), los niveles de malondialdehído (MDA) y del burnout y sus componentes. [Resultados]: No se han observado diferencias significativas entre varones y mujeres ni en la actividad de SOD y CAT, ni en los niveles de MDA ni en los niveles del burnout. Los niveles de MDA aumentan con la edad en profesionales sanitarios y en el grupo control, con diferencias significativas entre distintos grupos de edad. El estado civil no influye en las variables analizadas. [Conclusiones]: La peroxidación lipídica y el estrés laboral (niveles de burnout) disminuyen con la práctica de ejercicio físico, siendo los niveles más bajos para los que hacen ejercicio diariamente. Hacer deporte habitualmente, sobre todo cuando no es agotador, resulta una práctica beneficiosa para la prevención tanto del estrés oxidativo como del estrés laboral.

[EN]: [Background]: Stressful conditions lead to the formation of excessive free radicals which represents the greatest threat to cellular homeostasis of aerobic organisms. Burnout is a syndrome of chronic occupational stress. [Objectives]: This work focuses on the determination of both oxidative stress and occupational stress in a medical emergency service staff, and to analyze the effect that performing physical exercise can have on oxidative and occupational stress in these professionals. [Material and methods]: The study sample consisted of 70 professionals working in a medical emergency service and a control group of 80 age-matched healthy individuals. Superoxide dismutase (SOD) and catalase (CAT) activities, and malondialdehyde (MDA) were determined, as well as burnout with its components. [Results]: No significant variations were observed in SOD, CAT, MDA, or burnout levels as regards to gender. MDA levels increased with age in both the medical emergency service staff and the control group, with significant differences between the medical emergency service staff and the control group for all age groups. Marital status does not influence the variables analyzed. [Conclusions]: Lipid peroxidation and occupational stress (burnout levels) decrease with physical exercise, being lower levels for those who practice it daily. Playing sports regularly, especially when it is not exhausting, is a beneficial practice for preventing both oxidative stress and occupational stress.
