Geriatric Physical Therapy (GCS) Complete Practice Test 2026

The correct choice highlights that after 4 weeks of aerobic exercise, the risk of coronary heart disease (CHD) for older adults does not increase; in fact, it typically decreases. Engaging in regular aerobic exercise has been shown to strengthen the cardiovascular system, improve circulation, lower blood pressure, and enhance overall heart health, thereby reducing the risk of CHD.

As older adults participate in consistent aerobic activities, their heart rate (HR) may decrease at rest due to improved cardiovascular efficiency. Improvements in systolic blood pressure (BP) are also common, as regular exercise can lead to better vascular function and lower resting blood pressure. Furthermore, perceived exertion often decreases as individuals adapt to exercise; they become more accustomed to the effort required, making the exercise feel less strenuous over time.

In summary, the positive adaptations resulting from regular aerobic exercise in older adults contradict the notion that CHD risk would increase, establishing that option D is indeed the false statement.
