Exercise and Frailty in Older Adults

Physical activity is a promising strategy for improving muscle strength, endurance, and maximal aerobic power in older adults. Other improvements include flexibility, balance, motor control, and coordination. These benefits can result in decreased risk of falling while enhancing mobility. Exercise has also been shown to prevent or delay cognitive impairment, while increasing socialization and self-esteem. These benefits improve functional limitations and have important implications for maintaining or promoting independence in daily living activities, especially for those who are frail as a result of aging or disease.
An exercise program designed for frail individuals should reflect medical and social needs. Two major contributors that can determine a program's success are past exercise experience and goal setting; both of which should be discussed with the client prior to beginning a program. The camaraderie and relationship between the trainer and the client can greatly enhance the exercise program. An effective exercise plan for older, frail adults should not only be comprehensive and address functional needs, but should also be pleasurable, specific, realistic, and safe.
The primary goal for this population is to increase functional capacity and independence; therefore careful attention must be paid when choosing modes of activity. A multi-dimensional approach for improved health is important. Fitness professionals should choose exercises that activate large muscle groups and supply functional benefits, such as walking, cycling, rowing, swimming, as well as chair exercises. Performing aerobic physical activity 3-5 days per week and eventually accumulating 60 minutes of activity on these days, whether by continuous activity or in small bouts, should be a goal for your clients.
Adding strength training to the program will help increase overall muscular strength, decrease the risk of falling, and increase hand strength to assist with activities of daily living. It is suggested for frail individuals to start a strength training program without any weights and slowly progress from there. It should be a goal to incorporate 3 days of strength training per week with the sessions lasting 20 minutes. As with any other populations, flexibility training should be incorporated most days of the week.
It is also suggested with frail older adults that a comprehensive exercise program incorporate neuromuscular activities to increase gait, coordination, balance, flexibility, prevent falls, and increase hand-eye coordination and reaction times. Some of these activities can include one-foot stand, stair climbing, balloon activities, chair stand exercises, as well as practicing falling techniques.
While the benefits of an exercise program for older frail adults are numerous, there are several special considerations fitness professionals must be aware of when working with these individuals. Reaching target heart rate should not be the main focus of aerobic activity, instead try using RPE and the talk test to measure intensity levels. For aerobic exercise prescription, VO2peak, METs and RPE are often best. It is also suggested to avoid ballistic movements, neck circumduction, and isometric and static resistance exercise that may cause a dangerous increase in blood pressure.
The benefits of physical activity for frail older adults are well documented. With a comprehensive exercise program that includes neuromuscular activities, as well as focuses on functional activities and promoting independence, health fitness professionals can help older adults continue to stay independent.
