A sedentary lifestyle is the primary risk factor for muscle weakness. 1 Sarcopenia, defined as the loss of muscle mass and function, affects quality of life and increases the risk of physical limitations and disability among older adults. 1,2 Currently, epidemiological statistics show that sarcopenia affects about 50% of elderly people, depending on the country, ethnicity of the patient, diagnostic criteria and healthcare setting. [1][2][3][4] Overall, the prevalence among men is about 25% and among women, 20%. 2,5 Thus, loss of muscle mass appears to be an inevitable part of the aging process, especially with decreasing physical performance with aging. [5][6][7][8][9] Scientific evidence has shown that sarcopenia begins to develop between the ages of 30 and 40 years. It progresses with muscle mass declining by an average of 8% per decade between the ages of 40 and 70 years, and accelerates to 15% per decade from the age of 70 years onwards, with variation between men and women. 8,10 Sarcopenia is associated with functional decline, falls, disabilities and fractures, increased mortality among older adults and increased medical expenditure. [1][2][3][4][5] This disease has many causes, including genetics, nutritional deficiencies, metabolic disturbances, inflammation through production of proinflammatory cytokines by adipose tissue, physical inactivity 4,[11][12][13][14] and physical limitations. [15][16][17][18] Among all these risk factors, research has shown that the greatest cause of sarcopenia is insufficient physical activity and lack of exercise with advancing age, and this has attracted the attention of science and healthcare professionals who are involved in its treatment. 4,5,[12][13][14][15]
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
