The cause is age-related sarcopenia or sarcopenia with aging physically inactive people can lose as much as 3% to 5% of their muscle mass each decade after age 30 even if you are active, you’ll still have some muscle loss.
The name sarcopenia is derived from greek sarx (flesh) and penia (loss), literally meaning poverty of flesh sarcopenia is one of the four main reasons for loss of muscle mass, the others being anorexia, dehydration, and cachexia [7, 8. Sarcopenia is commonly associated with infiltration of fat into the muscle (sarcopenic obese) and an increase in connective tissue sarcopenia is very common, with a prevalence of ∼5% in persons aged 65 years and as high as 1 in two persons over the age of 80 years. Overview sarcopenia is the loss of muscle mass specifically related to aging it’s normal to lose some muscle mass as you age however, sarcopenia describes severe muscle loss that strays from. Sarcopenia is the loss of muscle mass in an older person the scientific definition is a measure of muscle mass loss that is two standard deviations less than the mean for young persons ( morley, 2008 morley, 2012 morley, 2012 steves et al, 2016 . Sarcopenia is the age-related decline in skeletal muscle mass concomitant with decreased strength and/or function  the concept of sarcopenia is being encountered with increasing frequency in clinical practice and research not sarcopenia: an overview.
It is not surprise that sarcopenia increase the risk of physical disability the risk of disability is 15 to 46 times higher in older persons with sarcopenia than in older persons with normal muscle men are at greater risk of sarcopenia related disability than women [16.
Sarcopenic obesity (so) refers to the copresence of sarcopenia and obesity in this condition, a disproportion exists between the amount of lean mass relative to fat mass research on so is important because the presence of both sarcopenia and obesity may have important health consequences.
The european working group on sarcopenia in older people suggested diagnosing sarcopenia when at least two of three criteria apply: (1) low muscle mass, (2) low muscle strength, and/or (3) low physical performance cutoff points are defined in a similar manner as by the consensus group mentioned before, namely 2 standard deviations below the mean reference value for muscle mass and muscle strength of a reference population and a gait speed ≤08 m/s. Sarcopenia is the loss of muscle mass specifically related to aging it’s normal to lose some muscle mass as you age however, sarcopenia describes severe muscle loss that strays from the norm.
