Leisure-Time Physical Activity, but not Commuting Physical Activity, is Associated with Cardiovascular Risk among ELSA-Brasil Participants

Arq. bras. cardiol; 110 (1), 2018
Abstract Background: Despite reports in the literature that both leisure-time physical activity (LTPA) and commuting physical activity (CPA) can promote health benefits, the literature lacks studies comparing the associations of these domains of physical activity with cardiovascular risk scores. Object...

El oxígeno suplementario no fue útil en personas con enfermedad pulmonar obstructiva crónica con desaturación moderada

Envelhecimento ativo: prevalência e diferenças de gênero e idade em estudo de base populacional

O objetivo deste estudo foi analisar as prevalências e as diferenças de gênero e idade em indicadores de envelhecimento ativo entre idosos participantes do Inquérito de Saúde do Município de Campinas, São Paulo, Brasil, 2014-2015. Estimaram-se as prevalências de participação dos idosos em doze ...

Age is the main factor related to expiratory flow limitation during constant load exercise

Clinics; 73 (), 2018
OBJECTIVE: The objective of this study was to investigate the interaction among the determinants of expiratory flow limitation (EFL), peak oxygen uptake (VO2peak), dysanapsis ratio (DR) and age during cycling at different intensities in young and middle-aged men. METHODS: Twenty-two (11 young and 11 mid...

¿Es útil el ejercicio en la prevención de infecciones respiratorias altas?

Medwave; 18 (4), 2018
INTRODUCCIÓN: Las infecciones respiratorias altas son una de las principales causas de consulta médica en el mundo. Dado que no hay tratamiento específico, la prevención es fundamental. Se ha postulado que el ejercicio tendría un rol preventivo, pero su real efectividad sigue siendo motivo de contro...

Level of performance and stability of cardiopulmonary variables in the intensity of the ventilatory anaerobic threshold

Motriz (Online); 24 (1), 2018
AIM: The aim of this study was to describe the behavior of different cardiopulmonary variables in exercise session with constant running speed, corresponding to the intensity of ventilatory anaerobic threshold and identifying the steady state in a different level of performance. METHODS: A cross-sectiona...

A program of physical activity improves gait impairment in people with Alzheimer's disease

Motriz (Online); 24 (1), 2018
AIM: This study aimed to identify the effects of aging and Alzheimer's disease (AD) on gait parameters after a four-month period and to investigate the effects of a four-month program of physical activity, with emphasis on the cognitive components of gait during single and dual task, in people with AD. ...

Aerobic training in aquatic environment improves the position sense of stroke patients: A randomized clinical trial

Motriz (Online); 24 (1), 2018
AIMS: (Stroke patients often present sensory-motor alterations and less aerobic capacity. Joint position sense, which is crucial for balance and gait control, is also affected in stroke patients). To compare the effect of two exercise training protocols (walking in deep water and on a treadmill) on the k...

Impacts of low or vigorous levels of physical activity on body composition, hemodynamics and autonomic modulation in Down syndrome subjects

Motriz (Online); 24 (1), 2018
Aim: We aimed to evaluate the effect of low and vigorous levels of physical activity in body composition, hemodynamics and autonomic modulation in subjects with Down syndrome (DS). METHODS: We evaluated 13 healthy subjects without DS (control group), 15 sedentary subjects with DS, (SED DS group), nine w...

Acute melatonin administration enhances aerobic tolerance: an analysis of biochemical and hematological parameters

Motriz (Online); 24 (2), 2018
Aims: This study is aimed at testing the acute melatonin administration (oral; 6 mg) on aerobic tolerance at cycloergometer and analyzing the consequences on biochemical and hematological parameters. Methods: The maximal aerobic capacity intensity (iMAC) at cycloergometer of eleven male healthy men (24....
