To investigate the relationships between regional skeletal muscle mass (SM mass) and bone mineral indices and to examine whether bone mineral content (BMC) normalized to SM mass shows a similar decrease with age in young through old age.One hundred and thirty-eight young and postmenopausal women ...
Muscle mass and performance (e.g., strength, speed, duration of muscular contraction) decrease throughout the aging process, and declines are associated with negative health outcomes such as falls and frailty [1, 2]. Objective measures of muscle strength such as peak torque, or the force produ...

Previous studies have shown that muscle mass decreases with age10,11. The CSA of the paraspinal muscles also tends to decrease with age, especially among the elderly, and lumbar muscle CSA is larger among men than women7,12. It is still unclear what happens to lumbar paraspinal musculature ...
Muscular atrophy means loss of muscle mass. When you have age-related sarcopenia, you have muscular atrophy. But muscular atrophy isn't always sarcopenia because it can have causes other than aging. For example, someone on bed rest or with a very inactive lifestyle can lose muscle mass at ...
摘要: Background: Whether low muscle mass is a risk factor for disability and mortality is unclear. Associations between approximations of muscle mass (including lean mass from dual-energy x-ray absorptiometry [DXA]), and these outcomes are inconsistent.关键词:...
age.Sarcopeniais thought to reflect mainly an age-related decrease in the synthesis of muscle protein rather than an excess catabolic process associated with disease or from reducedcaloric intake, although some have hypothesized that low-grade,chronic inflammationwith increasedprotein degradationmay ...
Percent body fat was estimated from FTH, and fat-free mass (FFM) was calculated. In men, a graded decrease in FFM was found in all age groups. In women, FFM was similar in the young and middle-aged groups, but was lower in the oldest group. Age was significantly and inversely ...
However, the cause of this age-associated loss of heterochromatin has remained enigmatic. Here we show that heterochromatin markers, including histone H3K9 di/tri-methylation and HP1, decrease with age in muscle stem cells (MuSCs) as a consequence of the depletion of the methyl donor S-...
No age or sex effects were noted for muscle endurance. However, muscles of active individuals demonstrated a greater resistance to fatigue than those of sedentary individuals. In conclusion, men were found to be stronger than women, age was associated with a decrease in muscle strength, but not...
