Bioelectrical Impedance Vectors Analysis of Sarcopenic Older Adults Submitted to a Resistance Training Program.

The objective of the present study is to analyze the changes in bioimpedance vector analysis (BIVA) and phase angle (PhA) in sarcopenic older people submitted to a 12-week resistance training (RT) program according to classic and specific analyses. To this end, 20 sarcopenic older adults of both sexes, invited through media, underwent bioimpedance analysis before and after the RT carried out three times a week, for 12 weeks. The mean impedance vectors of the groups established for the confidence ellipses (95% of the confidence ellipse) are compared using Hotelling's T test.

Older adults physically inactive in occupational and commuting domains have a higher risk for osteopenia and osteoporosis: A 12-month prospective study.

Unlabelled: The relationship between different domains of physical activity (PA) and bone health in older adults needs to be further investigated. We evaluated 379 Brazilian older adults and observed that the risk of osteopenia is higher in older adults who are physically inactive in occupational domain and for osteoporosis the risk is higher in physically inactive in commuting domain and total habitual PA.

Predictive equation for assessing appendicular lean soft tissue mass using bioelectric impedance analysis in older adults: Effect of body fat distribution.

Background: Low muscle mass is associated with sarcopenia and increased mortality. Muscle mass, especially that of the limbs, is commonly estimated by dual-energy X-ray absorptiometry (DXA) or bioimpedance analysis (BIA). However, BIA-based predictive equations for estimating lean appendicular soft tissue mass (ALST) do not take into account body fat distribution, an important factor influencing DXA and BIA measurements.

Sedentary Patterns Are Associated with Bone Mineral Density and Physical Function in Older Adults: Cross-Sectional and Prospective Data.

Aging causes some unfavorable morphological and functional changes, such as the decline in bone mineral density (BMD) and physical function. Moderate-to-vigorous physical activity (MVPA) and sedentary time seem to be related with these alterations, but the impact of distinct patterns remains unclear. The aim of this study was to cross-sectionally and prospectively assess the association between objectively measured MVPA and sedentary patterns (bouts and breaks) with BMD and physical function in older adults.

Occupational and leisure-time physical activity decreases the odds of disability in older adults: Prospective study.

Aging decreases physical function which can increase dependence in activities of daily living (ADL) and disability. However, physical activity (PA) may improve physical function and prevent disability in older adults. In addition, it is important to emphasize that research concerning the domains in which PA is practiced and the benefits for physical function of older adults is also important for the elaboration of preventative health measures for this population.

Physical activity is associated with functional capacity of older women with osteosarcopenic obesity: 24-month prospective study.

Background/objectives: Physical activity (PA) could be effective in the prevention of functional disability in older women, especially for those with body composition abnormalities. The aim this study was to analyze the association of total PA and in different domains with physical function and functional capacity in older women with or without osteosarcopenic obesity (OSO), as well as to assess the risk of functional disability in osteosarcopenic obesity older women insufficiently active.

Subjects/methods: The study included 152 Brazilian older women, aged 60 years and older.

Practice of physical activity and dysmobility syndrome in community-dwelling older adults.

The aim this study was to analyze the association between insufficient physical activity and dysmobility syndrome (DS) in community-dwelling older adults. In total, 375 subjects were evaluated aged ≥60 years. For the diagnosis of DS the presence of ≥3 clinical factors was considered: (a) low muscle mass; (b) low muscular strength; (c) low gait speed; (d) high body fat, and (e) osteoporosis.

Elastic resistance training improved glycemic homeostasis, strength, and functionality in sarcopenic older adults: a pilot study.

The purpose of this study was to verify the effects of 12 weeks of elastic resistance training on the glucose homeostasis, strength and functionally in sarcopenic older adults. Seven sarcopenic subjects (age, 70.71± 8.

Relationship between obesity, sarcopenia, sarcopenic obesity, and bone mineral density in elderly subjects aged 80 years and over.

Objective: This study sought to analyze the relationship between the components and aggravations of body composition (obesity, sarcopenia, and sarcopenic obesity) and bone mineral density in elderly subjects aged ≥80 years.

Methods: A cross-sectional study design was utilized to assess 128 subjects aged between 80 and 95 years. Body composition and bone mineral density were measured by dual energy X-ray absorptiometry.

Obesity, sarcopenia, sarcopenic obesity and reduced mobility in Brazilian older people aged 80 years and over.

Objective: To analyze which abnormalities in body composition (obesity, sarcopenia or sarcopenic obesity) are related to reduced mobility in older people aged 80 years and older.

Methods: The sample included 116 subjects aged 80 years and older. The body composition was measured using dual-energy X-ray absorptiometry (DXA) and mobility was assessed by motor tests.

Aim: To analyze the lipid profile of older people aged ≥80 years according to body composition (high fat mass, low muscle mass and both).

Material And Method: The sample consisted of 113 older people aged ≥80 years. The assessment of body composition was made using Dual Energy X-ray Absorptiometry (DXA) and the lipid profile analysis using an enzymatic colorimetric kit.

Is dynamometry able to infer the risk of muscle mass loss in patients with COPD?

Introduction: Sarcopenia is characterized by a progressive and generalized decrease of strength and muscle mass. Muscle mass loss is prevalent in patients with chronic obstructive pulmonary disease (COPD) as a result of both the disease and aging. Some methods have been proposed to assess body composition (and therefore identify muscle mass loss) in this population.

Indices of body fat distribution for assessment of lipodysthrophy in people living with HIV/AIDS.

Background: Metabolic and morphological changes associated with excessive abdominal fat, after the introduction of Antiretroviral Therapy, increase the risk of cardiovascular disease in people living with HIV/AIDS(PLWHA). Accurate methods for body composition analysis are expensive and the use of anthropometric indices is an alternative. However the investigations about this subject in PLWHA are rare, making this research very important for clinical purpose and to advance scientific knowledge.

Lipodystrophy in HIV/AIDS patients with different levels of physical activity while on antiretroviral therapy.

Introduction: Lipodystrophy is related to the use of highly active antiretroviral therapy (HAART) and can cause aesthetic stigma and increase the risk of developing cardiovascular diseases. Physical activity may be a valid alternative for the treatment and prevention of lipodystrophy. However, few studies address this issue.
