Question

as aging occurs, muscle contractions ______.

multiple choice

become absent
become slower
become faster
become stronger
do not change

Explanation:

Analyze physiological changes in aging muscle

Using the Effects of Aging on Muscles and Geriatric Musculoskeletal Changes knowledge points

• Aging leads to a progressive loss of skeletal muscle mass and strength, a condition known as sarcopenia.
• There is a reduction in the number and size of muscle fibers, particularly fast-twitch (Type II) fibers, which are responsible for rapid, powerful contractions.
• The nervous system also undergoes changes, including a decrease in motor units and slower nerve conduction velocity.
• Consequently, muscle contractions become slower and less forceful, rather than absent, faster, stronger, or unchanged.

Answer:

• become absent
• become slower (Correct answer)
• become faster
• become stronger
• do not change
