Genetic and Epigenetic Modulation of Cell Functions by Physical Exercise

2019

Since ancient times, the importance of physical activity (PA) and of a wholesome diet for human health has been clearly recognized. However, only recently, it has been acknowledged that PA can reverse at least some of the unwanted effects of a sedentary lifestyle, contributing to the treatment of pathologies such as hypertension and diabetes, to the delay of aging and neurodegeneration, and even to the improvement of immunity and cognitive processes. At the same time, the cellular and molecular bases of these effects are beginning to be uncovered. The original research articles and reviews published in this Special Issue on “Genetic and Epigenetic Modulation of Cell Functions by Physical Ex…

Körperliche Aktivität und deren Effekte auf das Burn-out-Syndrom

2020

ZusammenfassungDas vorliegende Review legt dar, dass regelmäßige körperliche Aktivität einen positiven Einfluss auf die Burn-out-Symptomatik hat. Mittels einer systematischen Literaturrecherche wurden die möglichen Effekte untersucht und die Evidenz mithilfe des Standard Index of Convergence (SIC) bewertet. Der SIC lag in den Längsschnittstudien bei SIC (3) = -1, während er in den Interventionsstudien bei SIC (6) = -0,50 lag. Daher ist jeweils von einer moderat star ken Evidenz auszugehen, dass körperliche Aktivität einen positiven gesundheitlichen Effekt auf das Burn-out-Syndrom hat. Aufgrund der Heterogenität der Erhebungstools und der Studienlage ist es notwendig, weitere qualitativ hoch…

Physical capacity in performing daily activities is reduced in scleroderma patients with early lung involvement

2015

Background and Aims Patients with systemic sclerosis (SSc) often complain reduced capacity at submaximal exercise; conversely, physical capacity in performing daily duties has never been measured in SSc. The aim of this study is to evaluate this performance and its correlates, in patients with SSc compared with healthy controls, in a free-living setting. Methods Twenty-seven outpatients with stable SSc and 11 controls were recruited. Physical activity was assessed by portable multiple sensor device (SenseWear Armband) worn for at least 6 days. Physical activity duration (PAD; in minutes) for non-sedentary activities and physical activity level (PAL = total daily energy/resting energy expend…

Leisure-time physical activity and artery lumen diameters: A monozygotic co-twin control study

2010

Exercise is thought to increase the diameter of the conduit arteries supplying the muscles involved. We studied the effects of a physically active vs inactive lifestyle on artery diameters in monozygotic (MZ) twin pairs discordant over 30 years for leisure-time physical activity habits. In a population-based co-twin control study design, six middle-aged (50-65 years) same-sex MZ twin pairs with long-term discordance for physical activity were comprehensively identified from the Finnish Twin Cohort (TWINACTIVE study). Discordance was initially defined in 1975 and the same co-twin remained significantly more active during the 32-year follow-up. The main outcomes were arterial lumen diameters …

In midlife, women experience hormonal changes due to menopausal transition. A decrease especially in estradiol has been hypothesized to cause loss of muscle mass. This study investigated the effect of menopausal transition on changes in lean and muscle mass, from the total body to the muscle fiber level, among 47–55-year-old women. Data were used from the Estrogenic Regulation of Muscle Apoptosis (ERMA) study, where 234 women were followed from perimenopause to early postmenopause. Hormone levels (estradiol and follicle stimulating hormone), total and regional body composition (dual-energy X-ray absorptiometry (DXA) and computed tomography (CT) scans), physical activity level (self-reported…

ACTIVIDAD FÍSICA Y DISCAPACIDAD: UN ESTUDIO CUALITATIVO CON MUJERES EN UN GIMNASIO ADAPTADO

2017

Este estudio explora cómo un grupo de mujeres con discapacidad (n=6) experimentan y perciben la práctica de actividad física en un gimnasio adaptado. Se utilizaron entrevistas semi-estructuradas como instrumento de recogida de datos cualitativos y se realizó un análisis temático inductivo. Los resultados se agruparon en torno a cuatro categorías temáticas emergentes: condición física y autonomía personal; papel paliativo del ejercicio; bienestar psicológico; relación social y apoyo. Destaca la experiencia satisfactoria de las participantes, en la que predomina una valoración positiva de procesos autorregulativos, la concepción social-relacional de la actividad física, y la relevancia del gi…

Health-related messages about physical activity promotion: an analysis of photographs on social networking sites of universities

2016

ABSTRACTThe main aim of this study was to examine how different physical activity domains are represented on the official social media sites of Spanish universities, through a content analysis of the photographs. Our results show that the representation of different physical activity domains is not balanced. While the analysed images do promote a message of gender equality in sedentary and leisure time physical activity behaviour, pictures illustrating active commuting and disabled groups were under-represented. We conclude that Internet-based physical activity promotion in university settings must to be guided by the principles of ‘health-promoting universities’ in the sense of promoting a…

Validation of Using Smartphone Built-In Accelerometers to Estimate the Active Energy Expenditures of Full-Time Manual Wheelchair Users with Spinal Co…

2021

[EN] This study aimed to investigate the validity of using built-in smartphone accelerometers to estimate the active energy expenditures of full-time manual wheelchair users with spinal cord injury (SCI). Twenty participants with complete SCI completed 10 5-min daily activities that involved the upper limbs, during which their oxygen consumption and upper limb activity were registered using a portable gas analyzer and a smartphone (placed on the non-dominant arm), respectively. Time series of 1-min averaged oxygen consumption and 55 accelerometer variables (13 variables for each of the four axes and three additional variables for the correlations between axes) were used to estimate three mu…
