Detailed explanation-1: -Muscle atrophy is the wasting (thinning) or loss of muscle tissue. People may lose 20 to 40 percent of their muscle and, along with it, their strength as they age.
Detailed explanation-2: -Reduced muscle bulk or muscle atrophy takes place when protein degradation exceeds protein synthesis, leading to a reduction of the cross-sectional area of myofibers and decreased muscle strength.
Detailed explanation-3: -Muscle atrophy is the wasting (thinning) or loss of muscle tissue.
Detailed explanation-4: -During muscle atrophy, proteolytic systems are activated, and contractile proteins and organelles are removed, resulting in the shrinkage of muscle fibers.
Detailed explanation-5: -A loss of muscle mass may be an inevitable result of the natural aging process. However, it can increase the risk of injuries and negatively impact a person’s overall quality of life.
