The Effects of Aging on Skeletal Muscle Aging Muscle (Essay Sample) Content: The Effects of Aging on Skeletal Muscle Aging muscleName Paper name Professors Name DateAging is a physiological practice, which is exemplify by the deterioration of the functioning of all organs and systems as a result of the regenerative capacity of cells and repair: depressed, the increased risk of vital structures such as the DNA due to environmental, chemical and physical toxins that irritate the mutations and, eventually, cancer or cancer risk, and decrease the size of the service life of the cell, which weakens the ability of organs and tissues.With progress age, all tissues, and organs suffer from changes in the normal capacity with it; muscles tend to suffer the most damage. The following changes are normally detected, Anatomy and Physiology in the field of musculoskeletal aging: reducing the total numbers of muscle fibers due to the depressed production capacity of the cells to produce proteins (Marieb, 2009). Decrease in the size of muscle fibers and tiss ues (also known as generic muscle atrophy). Total loss of muscle bulk, power and strength of all of the major muscle groups, such as the deltoids, biceps, triceps, hamstrings, gastrocnemius, etc. Wasting, or wear and tear of the cartilage in the joints, which is generally protected-acts as a shock absorber and the slip wheel agent, which prevents bone injuries and a stiffening of the friction force and the connective tissue elements fibrosis, which will reduce the range of motion and makes movement less efficient.The main effect is to reduce the aging of skeletal bone density, which occurs in both sexes the age of 50, and the tendency to inflammation and degeneration of the cartilage (Marieb, 2009).There is evidence that women may begin to lose bone density from the age of 30, depending on lifestyle and diet. Osteoporosis, osteoarthritis and rheumatoid arthritis are the most common conditions in older people and directly related to bone density, arthritis due to degeneration of the articular cartilage and destructive of collagen disease are believed to be an autoimmune component.The age of the cause of structural and functional changes in skeletal muscle in a wide variety of species such as humans. Muscle changes people to start in the fourth decade of life and results in frailty and injuries. The related changes in body composition to form in many metabolic disorders like insulin resistance, type 2 diabetes, hypertension, and hyperlipidemia, which leads to heart disease, and death increased. The decline of many muscle proteins, in particular, the myosin heavy chain and mitochondrial protein synthesis rates guaranteed to occur with age (Marieb, 2009).Mitochondrial biogenesis and ATP production reasons seem to reduce the mitochondrial DNA and messenger RNA. ATP production to reduce the muscle protein turnover, which requires energy. Aerobic exercise and resistance exercise improves muscle protein synthesis and mitochondrial biogenesis. Insulin and amino acids h ave also been shown to improve ...
