Using processes of muscular atrophy versus hypertrophy, how does aging affect muscular size and strength?

Solution

Muscular atrophy: Muscular atrophy is a decrease of weight of the body or mass of the muscle.

Hypertophy: Hypertrophy is a increase in the size of organ or volume of tissue cells due to enlargement of its component cells.

AGING AFFECT MUSCULAR SIZE AND STRENGTH:

1) Aging process leads to the decrease in muscle mass and strength.

2) In Human body physical changes between 20-30 are high.

3) The physical changes 30-50 is less.

4) Aging leads to distinct muscle mass and strength loss

5) Motor units, muscle fibres leads to the decline of muscle mass.

6) Major causes of strength depends on process of anabolic and loss of muscle depends upon catabolic.

7) It affects the growth hormones,androgen, estrogen,due to loss of anabolic factors.

8) The decrease in physical activity with aging process is the key factor in development of strength and muscle mass loss.

CONCLUSION : Aging process leads to a distinct mass muscle and strength loss.The decline of muscle stength of people compare between older & younger is 40.9% and 16.6% respectively.
