Influence of a virtual reality-based exercise protocol on the sit-to-stand activity kinematic variables in pregnant women: a randomized controlled trial

Motriz (Online); 23 (3), 2017
AIMS: Changes resulting from the gestational period may lead to changes in the biomechanics of women, which can alter the performance of functional activities such as sit-to-stand. Thus, the objective of this study was to investigate the influence of a virtual reality-based exercise protocol on the kinem...

Moderate physical training counterbalances harmful effects of low-protein diet on heart: metabolic, oxidative and morphological parameters

Motriz (Online); 23 (3), 2017
Aims: Maternal low-protein diet induces several impairments on cardiac system. Conversely, moderate exercise has been widely recommended to health improvement due to its effects on heart function. Thus, we investigated whether the moderate physical training is capable to offset the lasting injuries of a...

Effect of salbutamol on the cardiovascular response in healthy subjects at rest, during physical exercise, and in recovery phase: a randomized, double-blind, crossover study

Motriz (Online); 23 (3), 2017
Aim: To evaluate the effect of the short-acting beta agonists (SABAs) salbutamol on cardiovascular response rest, exercise and recovery phase. Methods: This study was conducted as a randomized, double-blind, placebo controlled, crossover study in 15 healthy adults, with a mean age of 30.2±6.6 years. Pa...

Outdoor gyms in Santiago: urban distribution and effects on physical activity

Motriz (Online); 23 (3), 2017
Abstract: Aims To put together a registry of the location of all existing outdoor gyms (OGs) in Santiago, Chile, and establish a profile of the users of these gyms. Methods: All OGs in Santiago located in public spaces were identified and geo-referenced, and an accessibility analysis of them was carried...

Performance Optimization in Sport: A Psychophysiological Approach

Motriz (Online); 23 (4), 2017
In the last 20 years, there was a growing interest in the study of the theoretical and applied issues surrounding psychophysiological processes underlying performance. The psychophysiological monitoring, which enables the study of these processes, consists of the assessment of the activation and function...

Exercise training reverse autonomic dysfunction and hypertension in rats fed with high-fat diet

Motriz (Online); 23 (4), 2017
AIMS: We evaluated whether exercise training ameliorates cardiovascular autonomic dysfunction in obesity-induced by high-fat diet (HFD) in rats. METHODS Wistar male rats were assigned in normal diet, sedentary (ND-S) and trained (ND-T) and HFD, sedentary (HFD-S) and trained (HFD-T). Blood pressure (BP),...

Effects of isometric handgrip training in patients with cardiovascular disease: rationale and design of the ISOPRESS network

Motriz (Online); 23 (4), 2017
Meta-analytical studies have indicated that isometric handgrip training promotes significant reduction in blood pressure in hypertensive patients with similar or greater decreases in blood pressure than observed after aerobic and dynamic resistance training. However, several gaps in the literature still ...

Multinomial model and zero-inflated gamma model to study time spent on leisure time physical activity: an example of ELSA-Brasil

ABSTRACT OBJECTIVE To compare two methodological approaches: the multinomial model and the zero-inflated gamma model, evaluating the factors associated with the practice and amount of time spent on leisure time physical activity. METHODS Data collected from 14,823 baseline participants in the Longitudi...

The effect of a self-constructed material on children's physical activity during recess

ABSTRACT OBJECTIVE To analyze whether an intervention supported by free play with a self-constructed material increases the level of physical activity of students during recess. METHODS The participants were 166 children of third to sixth grade, between nine and 12 years old (average = 10.64; SS = 1.13...
