Who is Dr. Leslie Kernisan and what is her area of expertise?
-Dr. Leslie Kernisan is a board-certified geriatrician and the founder of the website Better Health While Aging dot net. She specializes in the health issues that affect people over the age of 60 and discusses ways to prevent and manage these problems.
What is the main focus of the Better Health While Aging video podcast?
-The Better Health While Aging video podcast focuses on common health problems that affect people over age 60, discussing the best ways to prevent and manage those problems, as well as addressing concerns and dilemmas related to aging parents and older loved ones.
Why does Dr. Kernisan believe that exercise is crucial for older adults?
-Dr. Kernisan believes that exercise is crucial for older adults because it's not only valuable for better health outcomes but also for practical reasons that significantly impact how people experience their later years, such as maintaining physical abilities, independence, and quality of life.
What does Dr. Kernisan say about the common misconception regarding walking as a form of exercise for older adults?
-Dr. Kernisan points out that while walking is beneficial, many older adults may underestimate the value of other forms of exercise. Walking alone is not enough to maintain muscle strength, balance, and cardiopulmonary capacity, which are essential for maintaining independence and preventing falls.
How does exercise counteract the aging process at a cellular level?
-Exercise counteracts the aging process at a cellular level by activating various cellular pathways that improve cellular and organ function. This counters the aging process where cells and organs become less able to repair and maintain themselves, and it can slow down or even reverse some aspects of aging.
What are the four types of exercises that Dr. Kernisan recommends for older adults?
-Dr. Kernisan recommends four types of exercises for older adults: strength exercises (resistance exercises), aerobic exercises (endurance or cardio exercises), balance exercises, and flexibility exercises.
How often should older adults aim to perform each type of exercise according to Dr. Kernisan?
-Dr. Kernisan suggests that older adults should aim to perform strength exercises, aerobic exercises, balance exercises, and flexibility exercises at least twice a week, with strength training ideally done three times a week.
What is the significance of protein intake in relation to exercise for older adults?
-Protein intake is significant for older adults in relation to exercise because it helps in building and maintaining muscle strength. Combining adequate protein intake with strength training can help counteract frailty and sarcopenia, which are age-related losses of muscle and strength.
What advice does Dr. Kernisan give for those who want to encourage an older loved one to exercise?
-Dr. Kernisan advises taking a step back and trying to understand the older adult's perspective, motivations, and fears. It's important to model the behavior oneself and possibly invite the older adult to join in exercises. However, it's also crucial to accept that each individual makes their own choices about their health and lifestyle.
What are some of the risks associated with exercise that Dr. Kernisan discusses and how can they be managed?
-Dr. Kernisan discusses risks such as injury due to muscle or joint overuse, injury related to falling, and cardiopulmonary strain. These risks can be managed by consulting with health providers, starting with low-intensity exercises and gradually increasing them, giving the body rest days, listening to the body and stopping if pain is experienced, and considering treatment for osteoporosis if present.
How does Dr. Kernisan define frailty and what is its relationship with advanced age?
-Dr. Kernisan defines frailty as a state of physiologic vulnerability to stressors, where the body and mind are working but are easily harmed or pushed out of normal function. Frailty often manifests with weight loss, decreased grip strength, exhaustion, slower walking, and decreased physical activity. While frailty correlates with physical age, even robust older adults are more physiologically vulnerable at 90 than they were at 70.
What is the importance of an exercise plan and how can it be beneficial for older adults?
-An exercise plan is important as it provides a structured and organized approach to physical activity, ensuring that older adults engage in the right types of exercises on a consistent basis. It helps in maintaining motivation, avoiding injuries by gradually increasing exercise intensity, and ensuring that the exercise routine is tailored to the individual's needs and abilities.
