Which statement about sarcopenia is false?

• A. It is a gradual loss of muscle mass, strength, and function.
• B. It is a normal part of aging.
• C. It can be slowed by resistance training and proper nutrition.
• D. It is caused by an acute infection.

Answer: (D)

Sarcopenia is a progressive loss of skeletal muscle mass, strength, and function that tends to accompany aging. This decline develops over time due to a combination of aging-related changes in muscle biology, reduced activity, hormonal shifts, and often insufficient nutrition. Because it evolves with age and activity levels, it’s described as a common aging-related change, though not inevitable for every individual.

The statement that it is caused by an acute infection is not correct. Acute infections can create a temporary catabolic state and worsen weakness, but they do not initiate the chronic, gradual muscle loss that characterizes sarcopenia.

Resistance training and adequate nutrition can slow the progression by stimulating muscle protein synthesis and supporting energy and protein needs, helping preserve or even improve muscle mass, strength, and function.
