Effects of simple long-term respiratory care strategies in older men with COPD

J. bras. pneumol; 43 (6), 2017
ABSTRACT Objective: To evaluate a 24-month supervised, community-based maintenance exercise program after 3 months of pulmonary rehabilitation (PR) in comparison with a 27-month physical activity counseling program, in terms of the effects on maximal muscle strength, muscle power output, and exercise ca...

Cutoff values for appendicular skeletal muscle mass and strength in relation to fear of falling among Brazilian older adults: cross-sectional study

Säo Paulo med. j; 135 (5), 2017
ABSTRACT CONTEXT AND OBJECTIVE: Sarcopenia is an emerging public health issue in Brazil. Because of its high prevalence and the lack of national data, the objective here was to identify cutoff points for appendicular skeletal muscle (ASM) and handgrip strength in relation to fear of falling among Brazil...

Trait vs. state anxiety in different threatening situations

Abstract Objective Anxiety as a uni- or multidimensional construct has been under discussion. The unidimensional approach assumes that there is a general trait anxiety, which predisposes the individuals to increases in state anxiety in various threatening situations. In this case, there should be a cor...

Muscle strength and body composition in severe obesity

Clinics; 72 (5), 2017
OBJECTIVE: The aim of our study was to evaluate associations between maximum voluntary contraction torques of the lower limbs and body composition for subjects with severe obesity. METHODS: Body composition was evaluated by bioelectrical impedance analysis, and maximum voluntary contraction torques of t...

Jumping in aquatic environment after sciatic nerve compression: nociceptive evaluation and morphological characteristics of the soleus muscle of Wistar rats

Einstein (Säo Paulo); 15 (1), 2017
ABSTRACT Objective To evaluate the effect of jumping in aquatic environment on nociception and in the soleus muscle of trained and not trained Wistar rats, in the treatment of compressive neuropathy of the sciatic nerve. Methods Twenty-five Wistar rats were distributed into five groups: Control, Lesi...

Electrical stimulation attenuates morphological alterations and prevents atrophy of the denervated cranial tibial muscle

Einstein (Säo Paulo); 15 (1), 2017
ABSTRACT Objective To investigate if electrical stimulation through Russian current is able to maintain morphology of the cranial tibial muscle of experimentally denervated rats. Methods Thirty-six Wistar rats were divided into four groups: the Initial Control Group, Final Control Group, Experimental...

Cardiac Cachexia: Perspectives for Prevention and Treatment

Arq. bras. cardiol; 108 (1), 2017
Abstract Cachexia is a prevalent pathological condition associated with chronic heart failure. Its occurrence predicts increased morbidity and mortality independent of important clinical variables such as age, ventricular function, or heart failure functional class. The clinical consequences of cachexia ...

A practical approach to assess leg muscle oxygenation during ramp-incremental cycle ergometry in heart failure

Braz. j. med. biol. res; 50 (12), 2017
Heart failure is characterized by the inability of the cardiovascular system to maintain oxygen (O2) delivery (i.e., muscle blood flow in non-hypoxemic patients) to meet O2 demands. The resulting increase in fractional O2 extraction can be non-invasively tracked by deoxygenated hemoglobin concentration (...

Effects of a progressive resistance exercise program with high-speed component on the physical function of older women with sarcopenic obesity: a randomized controlled trial

ABSTRACT Background Sarcopenic obesity is associated with disability in older people, especially in women. Resistance exercises are recommended for this population, but their efficacy is not clear. Objective To evaluate the effects of a progressive resistance exercise program with high-speed component ...
