Impact of a Web-based exercise and nutritional education intervention in patients who are obese with hypertension : randomized wait-list controlled t…

2020

Background Internet-based interventions are a promising strategy for promoting healthy lifestyle behaviors. These have a tremendous potential for delivering electronic health interventions in scalable and cost-effective ways. There is strong evidence that the use of these programs can lead to weight loss and can lower patients’ average blood pressure (BP) levels. So far, few studies have investigated the effects of internet-based programs on patients who are obese with hypertension (HTN). Objective The aim of this study is to investigate the short- and long-term efficacy, in terms of body composition and BP parameters, of a self-administered internet-based intervention involving different …

Association of lifestyle factors and neuropsychological development of 4-year-old children

2020

Background: We aimed to assess how lifestyle factors such as diet, sleep, screen viewing, and physical activity, individually, as well as in a combined score, were associated with neuropsychological development in pre-school age children. Methods: We conducted a cross-sectional study in 1650 children of 4 years of age, from the Environment and Childhood Project (INMA) population-based birth cohorts in four regions of Spain. Children were classified per a childhood healthy lifestyle score (CHLS) with a range of 0 to 4 that included eating in concordance with the Mediterranean diet (1 point)

Leisure-time physical activity, sedentary behaviors, sleep, and cardiometabolic risk factors at baseline in the PREDIMED-PLUS intervention trial: A c…

2017

Limited data exists on the interrelationships between physical activity (PA), sedentary behaviors and sleep concerning cardiometabolic risk factors in aged adults at high cardiovascular disease risk. Our aim was to examine independent and joint associations between time spent in leisure-time PA, sedentary behaviors and sleep on the prevalence of obesity, type 2 diabetes (T2D) and components of the metabolic syndrome (MetS) in Mediterranean individuals at high cardiovascular risk. Cross-sectional analyses were performed on baseline data from 5776 Spanish adults (aged 55-75y in men; 60-75y in women) with overweight/ obesity and MetS, from October 2013 to October 2016, in the PREDIMED-PLUS tri…

Isotemporal substitution of inactive time with physical activity and time in bed: cross-sectional associations with cardiometabolic health in the PRE…

2019

Background: This study explored the association between inactive time and measures of adiposity, clinical parameters, obesity, type 2 diabetes and metabolic syndrome components. It further examined the impact of reallocating inactive time to time in bed, light physical activity (LPA) or moderate-to-vigorous physical activity (MVPA) on cardio-metabolic risk factors, including measures of adiposity and body composition, biochemical parameters and blood pressure in older adults. Methods: This is a cross-sectional analysis of baseline data from 2189 Caucasian men and women (age 55-75 years, BMI 27-40 Kg/m(2)) from the PREDIMED-Plus study (http://www.predimedplus.com/). All participants had >= 3…

Análisis del tiempo de lucha y no lucha en taekwondistas cadetes

2016

La relación entre los tiempos de lucha (L) y no lucha (NL) ha sido utilizada para caracterizar las demandas físicas del taekwondo. El objetivo del presente estudio es analizar el tiempo de L y NL en función de la categoría de competición en taekwondistas cadetes (12-14 años). Se analizaron las fases del tiempo de movimiento (L y NL) de 47 combates del primer Campeonato del Mundo Cadete en función de la categoría de competición (minimosca, mosca, gallo, pluma, ligero, superligero, semimedio, medio, semipesado y pesado). Se utilizó el test Kruskal-Wallis seguido de las pruebas por pares de U de Mann Whitney para analizar las diferencias entre grupos (p < 0,05). Se encontraron diferencias sign…

Effects of moderate vs. high iso-inertial loads on power, velocity, work and hamstring contractile function after flywheel resistance exercise.

2019

Flywheel iso-inertial training has been shown to positively affect muscular strength and sports performance (e.g. agility). However, implementing such eccentrically-biased training during a microcycle needs to be carefully planned due to its purported effects on the neuromuscular system that can last for hours/days post-exercise. This study aimed at using tensiomyography to verify the effects of different inertias during the hip extension exercise on the contractile function of biceps femoris and semitendinosus muscles of the dominant leg for up to 72 hours post-exercise. Thirty participants (24.4 ± 3.4 years) were divided into 0.075 or 0.1 kg·m2 inertia groups and a control group. Magnitud…

Efectos agudos de una sesión de entrenamiento vibratorio sobre la espasticidad en personas con Esclerosis Múltiple: resultados preliminares.

2020

La esclerosis múltiple (EM) es una enfermedad neurológica progresiva, que conduce a un declive de la función física, siendo la espasticidad uno de los síntomas más recurrentes en esta población. En los últimos años, el entrenamiento vibratorio de cuerpo completo (WBVT) ha mostrado beneficios en la capacidad funcional, la función neuromuscular o la calidad de vida en personas con EM. Sin embargo, los efectos agudos de una sesión de WBVT sobre variables como la espasticidad son todavía desconocidos. Por ello, los objetivos principales de este estudio fueron analizar los efectos agudos del WBVT sobre la espasticidad de la rodilla, así como conocer las diferencias en esta variable entre la pier…

RELATIONSHIP BETWEEN TRAINING VOLUME AND BONE MINERAL DENSITY CHANGES IN ELDERLY WOMEN

2016

ABSTRACT Introduction: Several studies have analyzed the relationship between physical activity and bone density. However, the prescription of exercise is not entirely clear as to the type, quantity and intensity. Objective: The objective of this study was to determine if there is a relationship between the amount of exercise and changes in bone mineral density. Methods: Fifty-two women, members of the Municipal Program of Physical Activity for Seniors, voluntarily underwent two ultrasonographies of the calcaneus within a 6-month interval. During this period, all physical activity was recorded. Afterwards, a lineal correlation study was carried out between the amount of exercise and bone ch…
