BACKGROUND Frailty has become the center of attention of basic, clinical, and demographic research because of its incidence level and the gravity of adverse outcomes with age. Moreover, with advanced age, motor variability increases, particularly in gait. Muscle quality and muscle power seem to be closely associated with performance on functional tests in(More)
to compare the different adipose tissue (AT) compartments, muscle mass, muscle fat infiltration, coronary calcium, as well as associations among changes in different AT compartments between frail and robust nonagenarians. Forty-two elderly subjects took part in this study: 29 institutionalized frail elderly (92.0 ± 8 years) and 13 robust elderly (88.2 ± 4.1(More)
This randomized controlled trial examined the effects of multicomponent training on muscle power output, muscle mass, and muscle tissue attenuation; the risk of falls; and functional outcomes in frail nonagenarians. Twenty-four elderly (91.9 ± 4.1 years old) were randomized into intervention or control group. The intervention group performed a twice-weekly,(More)
This study examined the neuromuscular and functional performance differences between frail oldest old with and without mild cognitive impairment (MCI). In addition, the associations between functional capacities, muscle mass, strength, and power output of the leg muscles were also examined. Forty-three elderly men and women (91.9±4.1 years) were classified(More)
The purpose of this study was to compare the vascular calcification in thoracic aorta (TAC), abdominal aorta (AAC), iliac arteries (IAC), and femoral arteries (FAC) and bone mineral density (BMD) of the lumbar vertebrae between frail and robust nonagenarians, as well as to verify the associations between vascular calcification with BMD, muscle tissue(More)
BACKGROUND Several studies have stated that frailty is associated with cognitive impairment. Based on various studies, cognition impairment has been considered as a component of frailty. Other authors have shown that physical frailty is associated with low cognitive performance. Dual task gait tests are used as a strong predictor of falls in either dementia(More)
PURPOSE To compare the effects of 12-week training periods (2 d·wk) involving resistance training only with the effects of 12-week training periods involving combined resistance (once weekly) and endurance (once weekly) training on strength, endurance performance, and quality of life. METHODS Thirty-six patients with moderate-to-severe chronic obstructive(More)
BACKGROUND An inspiratory capacity to total lung capacity (IC/TLC) ratio of ≤25% has emerged as a better marker of mortality in chronic obstructive pulmonary disease (COPD) patients. The relationship among the IC/TLC ratio to lower extremity skeletal muscle function remains unknown. METHODS Thirty-five men with moderate to severe COPD were divided into(More)
Cognitive impairment has a harmful effect on quality of life, is associated with functional limitations and disability in older adults. Physical activity (PA) has shown to have beneficial effects on cognition but the results and conclusions of randomized controlled trials (RCTs) are less consistent. Update of knowledge was necessary to examine the effects(More)
The objective of this study was to investigate dual-task costs in several elderly populations, including robust oldest old, frail oldest old with MCI, frail oldest old without MCI, and frail elderly with dementia. Sixty-four elderly men and women categorized into frail without MCI (age 93.4 ± 3.2 years, n = 20), frail with MCI (age 92.4 ± 4.2 years, n =(More)
