Final answer:
To maintain functional mobility in older adulthood, regular exercise, especially low-impact activities like swimming and biking, and destressing joints through rest and the use of mobility aids, are effective methods.
Step-by-step explanation:
The two most common methods of maintaining functional mobility in older adulthood are exercise and destressing joints. Engaging in regular physical activities such as swimming, water aerobics, and biking helps maintain joint mobility and muscle strength, which are essential for preventing joint stress and keeping bones correctly aligned in their joints.
Additionally, efforts to decrease stress on joints can involve using mobility aids such as canes, resting, and, in cases of excess weight, pursuing weight loss to further reduce the strain on weight-bearing joints.
