Sarcopenia, the age-related decline in muscle mass, affects the muscle strength and muscle quality, and these changes decrease functional capacity. The prevalence of thyroid dysfunction increases with age, and changes in thyroid hormone level lead to neuromuscular deficits. We investigated the effects of subclinical hypothyroidism on the muscle mass, strength or quality in elderly people. One t...

conclusions independent of the training sequence, an 8-week concurrent training program caused positive changes in the body composition and physical fitness of our aged female subjects. however, there was no benefit derived from sequence order training. results the intra-session sequence order did not influence the adaptive response of the waist-to-hip ratio (p = 0.55), body fat percentage (bf ...

To maintain muscle mass in older age, several aspects regarding the amount and distribution of protein intake have been suggested. Our objective was to investigate single and combined associations of daily protein intake, evenness of protein distribution across the three main meals, number of meals providing ≥0.4 g protein/kg body weight (BW), and number of meals providing ≥2.5 g leucine, with ...

Background: One of the important issues in aging is sarcopenia characterized by muscle mass and function reduction. The present study investigated the effect of high intensity interval resistance training (HIIRT) on muscular parameters in sarcopenic elderly women. Methods: A total of 30 sarcopenic women aged 60 to 70 years (appendicular skeletal muscle mass index<6.76 kg/m2, hand grip<20 kg) w...

Adequate skeletal muscle strength is essential for physical functioning and low muscle strength is a predictor of physical limitations. Older adults with diabetes have a two- to threefold increased risk of physical disability. However, muscle strength has never been investigated with regard to diabetes in a population-based study. We evaluated grip and knee extensor strength and muscle mass in ...

PURPOSE To determine the prevalence of sarcopenia and investigate relationships among body composition, muscle strength, and physical function in elderly women in low-level aged care. SUBJECTS AND METHODS Sixty-three ambulatory women (mean age 86 years) participated in this cross-sectional study where body composition was determined by dual energy X-ray absorptiometry (DXA); ankle, knee, and ...

Poor muscle strength is associated with mortality, presumably due to low muscle mass. Notably, muscle power declines more rapidly than muscle strength with increasing age, which may be related to more complex central nervous system movement control. We examined arm-cranking power against four workloads and isometric strength measured in the upper extremities of 993 men longitudinally tested ove...

BACKGROUND A short period of leg immobilization leads to rapid loss of muscle mass and strength. Creatine supplementation has been shown to increase lean body mass in active individuals and can be used to augment gains in muscle mass and strength during prolonged resistance-type exercise training. OBJECTIVE Our objective was to investigate whether creatine loading can attenuate the loss of mu...

Objective To determine if there is muscle mass reduction in patients with ankylosing spondylitis (AS) compared to the general population and to examine the relationship between skeletal muscle mass, quality of life (QOL), strength, and mobility in patients with AS. Methods A total of 30 AS patients were enrolled in this study. Skeletal muscle mass was measured by bioelectrical impedance analy...
