What change occurs with aging?

Multiple Choice

О

Increased production of creatine phosphate

Increased suppy of ATP

О

Increased muscle fiber diameter

О

Decreased supply of myoglobin

Verified Answer :

Final answer:

Aging leads to a decreased supply of myoglobin, impacting muscle endurance and function. It is also associated with reduced muscle mass and energy availability. Overall, these changes can adversely affect physical performance.


Explanation:

Changes in Muscle Physiology with Aging

Aging is associated with various physiological changes in the human body, particularly in muscle tissue. One significant change that occurs is a decreased supply of myoglobin.

Myoglobin is an essential protein responsible for oxygen storage in muscle cells, and its decreased levels can lead to a reduction in muscle endurance and strength over time. As we age, there are also changes in muscle fiber composition, leading to a decline in muscle mass and the overall metabolic capacity of muscles.

Other Potential Changes Include:

  • Decreased production of creatine phosphate, which affects energy availability.
  • Reduced ATP supply, impacting muscle contraction efficiency.
  • Changes in muscle fiber diameter, with a tendency to lose fast-twitch fibers.

These factors contribute cumulatively to the decreased physical performance often observed in older adults.
