A lot of exercise in old age helps prevent illnesses and relieve symptoms. But it’s not just the body that benefits from it. This is shown by two new studies.
An active lifestyle with lots of exercise can also stimulate the brain. Scientific studies show that regular exercise not only strengthens muscles,but also improves mental performance. This effect can apparently last longer than previously thought. This is what researchers from Great Britain and the USA are currently reporting.
As part of a study, a team of researchers from the Advent Health Research Institute in Orlando, Florida, evaluated data from 650 study participants who first trained on a treadmill and then answered questions. The test subjects were between 65 and 80 years old. During the evaluation, the study authors took into account various aspects such as the processing speed of information, short-term memory as well as visual-spatial perception and planning skills.
The key finding: Better physical fitness went hand in hand with better results in all cognitive tests. Interestingly, neither the exact age nor the presence of Alzheimer’s risk genes played a role in these positive effects.
The researchers suspected several mechanisms behind this: Regular exercise could promote blood circulation and the formation of new nerve cells in the brain, reduce oxidative stress, and change the shape and structure of the white and gray matter in the brain. The latter improves the ability to process information and emotions.
Another study by British researchers recently came to the conclusion that the effect can even last for 24 hours. In an observational study, physical activity led to measurably better brain performance in older people the next day. Study participants between the ages of 50 and 83 who were more physically active than usual the day before performed better on memory tests the following day. Less time sitting and at least six hours of sleep also correlated with better test results the next day.
Dr. Mikaela Bloomberg from University College London said in a press release: “The benefits of physical activity on short-term memory may last longer than previously thought.” And: “Moderate or intense activity is anything that increases your heart rate – brisk walking, dancing or climbing stairs are enough.” So it doesn’t have to be a strict sports program or endurance training.
What are the best types of exercise for improving cognitive health in older adults?
Interview: The Vital Link Between Exercise and Cognitive Health in Older Adults
In this engaging Q&A, our time.news editor speaks with Dr. Mikaela Bloomberg from University College London, an expert in cognitive health and aging, to explore the profound benefits of exercise on both physical and mental well-being among older adults.
Editor: Thank you for joining us, Dr. Bloomberg. Your recent research has highlighted some remarkable findings about exercise and its impact on cognitive health in older adults. What did your studies reveal?
Dr. Bloomberg: Thank you for having me! Our research indicates that regular physical activity substantially boosts cognitive function in older adults. Not just in terms of physical improvements, but also in aspects like processing speed, short-term memory, and planning skills. Notably, we found that individuals between 65 and 80 years old showed better cognitive test results correlated with better physical fitness, irrespective of thier age or presence of Alzheimer’s risk genes.
Editor: That’s interesting! Can you elaborate on the potential mechanisms that link physical fitness to cognitive performance?
Dr. Bloomberg: Certainly! There are several mechanisms at play. Regular exercise enhances blood circulation, which can promote the formation of new nerve cells in the brain. additionally, it appears to reduce oxidative stress and positively alters the shape and structure of the brain’s white and gray matter. These changes improve our ability to process data and emotions, leading to better cognitive performance.
Editor: The implications of this research seem critical. What did you discover regarding the lasting effects of exercise on mental performance?
Dr. Bloomberg: One of our key findings was that the cognitive benefits of physical activity can last for up to 24 hours. In our observational study, we noticed that older adults who were more active than usual the day before performed significantly better on memory tests the following day. This emphasizes the importance of not just regular exercise but also staying active day-to-day and maintaining a routine that includes physical activity.
Editor: What type of physical activities can older adults engage in to experiance these benefits? are high-intensity workouts necessary?
Dr. Bloomberg: Not at all! The intensity of exercise is less critical than the fact that the activity increases your heart rate. Moderate to intense activities—which can simply include brisk walking, dancing, or climbing stairs—are completely effective. The key is consistency and incorporating some form of movement into daily life.
Editor: That’s reassuring for many seniors looking to improve their health without the pressure of rigorous training. What practical advice can you provide to our readers, especially older adults, to implement more physical activity into their lives?
Dr. Bloomberg: Start small and make it enjoyable! Engage in activities you love and look for opportunities to be active, such as walking with friends or joining local dance classes. Minimizing sedentary behavior, alongside ensuring adequate sleep—at least six hours—can enhance cognitive function significantly.Setting daily goals for movement can also be a motivating factor.
Editor: Considering this research, how do you see the healthcare industry adapting to these findings regarding exercise and cognitive health?
Dr. Bloomberg: There’s a growing acknowledgment within the healthcare community about the importance of lifestyle interventions for mental health. We anticipate more healthcare initiatives emphasizing physical activity as a core component of cognitive health programs for older adults. Additionally, research will likely continue to focus on the direct benefits of exercise, pushing for greater integration of fitness programs into senior care models.
Editor: Thank you, Dr. Bloomberg, for sharing these valuable insights. It’s clear that embracing an active lifestyle not only enriches physical health but also plays a meaningful role in maintaining cognitive sharpness in older age.
Dr. Bloomberg: It was my pleasure! I encourage everyone to prioritize movement in their lives—it’s never too late to start reaping the benefits of exercise!
