Adherencia a la dieta mediterránea en adultos inactivos, practicantes de ciclo indoor y ciclistas aficionados

Introducción: existe información limitada sobre la relación entre la adherencia a la dieta mediterránea (ADM) y la práctica deportiva. Objetivo: determinar la posible asociación de la práctica deportiva y el volumen de entrenamiento en bicicleta con la ADM y la influencia de la proximidad de una prueba ciclodeportiva sobre la ADM. Material y métodos: una primera evaluación de la ADM en 785 (84 mujeres) ciclistas aficionados (volumen = 7 horas/semana), 514 (224 mujeres) practicantes de ciclo indoor (volumen: 2-6 horas/semana) y 718 (411 mujeres) adultos inactivos fue desarrollada en mayo, coincidiendo con la participación de los ciclistas en una prueba ciclodeportiva. Una submuestra de 359 ciclistas y 148 inactivos fueron evaluados nuevamente en noviembre, en fecha alejada de la prueba ciclodeportiva. Se utilizó el cuestionario MEDAS-14 para valorar la ADM y un cuestionario autodiseñado para evaluar el volumen de entrenamiento. Resultados: un 40% de los sujetos evidenció alta ADM. En ambos sexos, los deportistas mostraron mayor ADM que los inactivos, con los mejores índices para los grupos de ciclistas (p < 0, 001). La relación entre la ADM y el volumen de entrenamiento fue débil (hombres: r = 0, 137, mujeres: r = 0, 173; p < 0, 001). La ADM de los ciclistas disminuyó de mayo a noviembre (p < 0, 001) sin cambios en los sujetos inactivos (p = 0, 535). Conclusiones: la práctica deportiva en bicicleta se asocia con una mayor ADM con limitada influencia del volumen de entrenamiento y con efectos positivos transitorios de la participación en una prueba ciclodeportiva. Introduction: There is limited information referred to the relationship between adherence to the Mediterranean Diet (AMD) and sports practice. Objective: To determinate the association of cycling practice and cycling training volume with the AMD and the influence of the participation in a high-demand cyclist event on the AMD. Material and methods: A first evaluation of AMD in 785 (84 women) amateur cyclists (volume: = 7 hours/week), 514 (224 women) indoor cycling practitioners (volume: 2-6 hours/week) and 718 (411 women) inactive adults was conducted in May coinciding with the participation of cyclists in a cycling event. A subsample of 359 cyclists and 148 inactive subjects agreed to be retested in November, far from the cycling event date. The MEDAS-14 questionnaire was used to assess the AMD and a self-designed questionnaire was used to assess the volume of training. Results: 40% of subjects showed high AMD. In both sexes, athletes showed higher AMD than inactive subjects, with the highest indexes for groups of cyclists (p < 0.001). The relationship between AMD and training volume was weak (men: r = 0.137, women: r = 0.173; p < 0.001). The AMD of cyclists decreased from May to November (p < 0.001) with no significant changes in inactive subjects (p = 0.535). Conclusions: Cycling is associated to higher values of AMD with a limited influence of training volume and transient positive effects of participation in a cycling endurance event

Assessing Physical Activity in People With Mental Illness: 23-country Reliability and Validity of the Simple Physical Activity Questionnaire (SIMPAQ)

Background: Physical inactivity is a key contributor to the global burden of disease and disproportionately impacts the wellbeing of people experiencing mental illness. Increases in physical activity are associated with improvements in symptoms of mental illness and reduction in cardiometabolic risk. Reliable and valid clinical tools that assess physical activity would improve evaluation of intervention studies that aim to increase physical activity and reduce sedentary behaviour in people living with mental illness. Methods: The five-item Simple Physical Activity Questionnaire (SIMPAQ) was developed by a multidisciplinary, international working group as a clinical tool to assess physical activity and sedentary behaviour in people living with mental illness. Patients with a DSM or ICD mental illness diagnoses were recruited and completed the SIMPAQ on two occasions, one week apart. Participants wore an Actigraph accelerometer and completed brief cognitive and clinical assessments. Results: Evidence of SIMPAQ validity was assessed against accelerometer-derived measures of physical activity. Data were obtained from 1010 participants. The SIMPAQ had good test-retest reliability. Correlations for moderate-vigorous physical activity was comparable to studies conducted in general population samples. Evidence of validity for the sedentary behaviour item was poor. An alternative method to calculate sedentary behaviour had stronger evidence of validity. This alternative method is recommended for use in future studies employing the SIMPAQ. Conclusions: The SIMPAQ is a brief measure of physical activity and sedentary behaviour that can be reliably and validly administered by health professionals.Universidad Pablo de Olavide de Sevilla.
