What statement about musculoskeletal changes during aging is false?

The statement indicating that bed rest is needed because of loss of strength is not accurate. While it is true that aging can lead to a decrease in muscle strength, prolonged bed rest can actually exacerbate the loss of strength and lead to a further decline in mobility and independence. Maintaining an active lifestyle and engaging in regular physical activity is often recommended to help preserve muscle strength and function in older adults. This approach helps counteract the negative effects of aging on the musculoskeletal system, such as muscle mass decline and bone density loss. In contrast, the other statements reflect true aspects of the aging process, including joint stiffness, decreased bone density, and reduced muscle mass, all of which are common changes experienced as one ages.
