One of the most striking effects of age is the involuntary loss of muscle mass, strength, and function, termed sarcopenia [1–3]. Muscle mass decreases approximately 3–8% per decade after the age of 30 and this rate of decline is even higher after the age of 60 [4,5].Age-related changes in muscle
Muscle tissue is replaced more slowly and lost muscle tissue is replaced with a tough, fibrous tissue. Changes in the nervous system cause muscles to have reduced tone and ability to contract.
Is muscular strength influenced by age
Aging process leads to a distinct muscle mass and strength loss. The decline of the muscle strength of people, who were younger than 40 years, in comparison to those, who were older than 40 years was ranged between 16.6% and 40.9%.
