Assessment of the muscle strength of older adults cannot be compared with that of younger adults because
a. stroke is more common in older adults.
b. nutritional status is better in younger adults.
c. young people exercise more than older adults.
d. aging leads to a decrease in muscle bulk and strength.
D
With age, muscle fibers deteriorate and are replaced by fibrous connective tissue. Muscle atrophy is accompanied by a reduction in muscle mass, a loss of muscle strength against resistance, and a reduction in overall body mass. Although stroke is more common in older adults, this is not associated with muscle strength. Nutritional status is usually better in younger adults, and young people tend to exercise more than older adults. However, neither of these factors is related to the inability to compare muscle strength of older adults with younger adults.
