An FP’s guide to exercise counseling for older adults

Time. The 2018 Physical Activity Guidelines for Americans recommend a specific duration of physical activity throughout the week; however, as with frequency, it is important to remember that duration of exercise is individualized (TABLE 2²). Older adults should be as physically active as their abilities and comorbidities allow, and in the setting of frailty, numerous comorbidities, and/or a sedentary lifestyle, it is reasonable to initiate exercise recommendations with shorter durations.

The PAVS is a 2-item self-report measure used to quickly assess a patient’s level of physical activity.

Type of exercise. As noted in the 2018 Physical Activity Guidelines for Americans, recommendations for older adults include multiple types of exercise. In addition to these general exercise recommendations, exercise prescriptions can be individualized to target specific comorbidities (TABLE 2²). Weight-bearing, bone-strengthening exercises can benefit patients with disorders of low bone density and possibly those with osteoarthritis.^3,23 Patients at increased risk for falls should focus on balance-training options that strengthen the muscles of the back, abdomen, and legs, such as tai chi.^3,23 Patients with cardiovascular risk can benefit from moderate- to high-intensity aerobic exercise (although exercise should be performed below anginal threshold in patients with known cardiovascular disease). Patients with type 2 diabetes achieve improved glycemic control when engaging in combined moderate-intensity aerobic exercise and resistance training.^7,23

Referral to a physical therapist or sport and exercise medicine specialist can always be considered, particularly for patients with significant neurologic disorders, disability secondary to traumatic injury, or health conditions.³

An improved quality of life. Incorporating physical activity into older adults’ lives can enhance their quality of life. Family physicians are well positioned to counsel older adults on the importance and benefits of exercise and to help them overcome the barriers or resistance to undertaking a change in behavior. Guidelines, recommendations, patient history, and resources provide the support needed to prescribe individualized exercise plans for this distinct population.
