In my career as a doctor, I have encountered a variety of questions, but one question has always stuck with me: Why do we walk slower with age, and does this mean that our health is declining? One day, a patient in his seventies, whom I call Mr. Wang, came to my clinic. His question seems simple: he notices that he is walking slower than he did a few years ago, and he worries whether this is a sign that his health is deteriorating or, worse, whether it means that his life is shortening.
Mr. Wang is a lover of life, he was a teacher before retiring, and he still maintains a positive attitude towards life after retirement, often participates in community activities, and likes to walk in the morning. But recently, he found himself falling further and further behind his friends on his walks, and he was starting to feel tired. This made him feel anxious and uneasy, so he decided to seek professional advice.
Behind this simple appeal, there are complex physical, psychological, and social issues. As a doctor, I know that walking speed is not just an aspect of physical activity, it is also one of the important indicators to assess a person's overall health. And for seniors like Mr. Wang, it's especially important to understand the link between walking speed and health.
When dealing with Mr. Wang's problem, I have to take into account not only his physical health, but also his mental health and social interactions. My goal is not only to help him understand why people walk slower as they get older, but more importantly, I want to give him some practical advice to help him stay active and maintain an optimistic outlook on life.
A scientific study of walking speed and longevity
In my outpatient routine, I often encounter older patients who are curious about the correlation between walking speed and health. They often ask, "Doctor, I'm walking slower now, does that mean I'm not that healthy anymore?" and it makes me think, is the speed at which we walk really predicting our longevity? Let me share some scientific research with you.
In recent years, studies have pointed out that walking speed is indeed related to a person's lifespan. Studies have shown that people who walk fast live longer on average than those who walk slower. The discovery spanned gender and body type, meaning that both men and women were fat and thin, and fast walking seemed to be a sign of health and longevity
Why brisk walking predicts longevity?First of all, brisk walking is usually a reflection of a person's overall physical condition. This includes better cardiorespiratory fitness, stronger muscles, and greater flexibility. Secondly, brisk walking is also associated with an active lifestyle, such as regular exercise, a healthy diet, and effective stress management.
However, we must also consider that this association does not imply a direct causal relationship. That is, just by speeding up walking, it may not directly prolong life. But it does serve as a reference point for assessing health status.
These findings have implications for each of us. First, it encourages us to maintain an active lifestyle, including regular aerobic exercise such as brisk walking. Second, it reminds us that noticing changes in the body, such as changes in walking speed, can be an early sign of a change in health.
Finally, for those who find themselves walking slower, this is a great opportunity to check their health and consider lifestyle adjustments. Whether you need to increase physical activity, improve your eating habits, or seek medical advice, it is worth considering.
Aging and Slowing Walking: Understanding the Natural Processes of the Body
When I'm in the outpatient clinic, I often have elderly patients ask me, "Doctor, what's wrong with me, how does it feel like a snail race when I used to walk like the wind?" So why do we walk slower as we age?
First of all, understand that this is a natural physiological process. As we age, our bodies undergo various changes, which include a decrease in muscle mass and reduced joint flexibility. Muscles are the source of motivation for our actions, and the decline in muscle strength will directly affect our mobility. It's like when the horsepower of the vehicle decreases, the speed naturally slows down.
Let's look at joint flexibility. Joints are an important part of connecting bones, and their flexibility is directly related to the amplitude of our movements. As you age, your synovial fluid may decrease and the soft tissues around your joints become less flexible, making movement harder and slower.
I remember an old gentleman who came to visit me and he complained that he was walking more and more slowly lately and that he often felt sore legs. After examination, it was found that in addition to the wear and tear of the joints, the strength of his leg muscles was also significantly less than before. This is a prime example of why older people feel slower to walk.
So, what can we do to combat or mitigate this process? The first is to maintain a moderate amount of exercise. Even a simple walk or activity in the water can effectively maintain muscle strength and joint flexibility. Secondly, a balanced diet is also crucial, with moderate intake of protein and other nutrients to help maintain muscle health. Finally, regular health check-ups are needed to identify and address health issues that may affect mobility.
How to maintain or increase walking speed
During my clinic time, I often encounter patients who are curious about the changes in their walking speed, especially their elderly friends. They often ask, "Doctor, if I'm walking slowly, does that mean I'm not healthy?" Not only that, but scientific studies have also shown that walking speed is closely related to our longevity. But more importantly, regardless of age, we all have ways to maintain or even increase our walking speed, and here are some specific suggestions.
Tips for different age groups to keep moving
Adolescents & Adults: At this stage, the focus is on establishing and maintaining good physical activity habits. Regular aerobic exercise, such as brisk walking, jogging or swimming, can boost your heart and lungs and muscle strength, which can help you maintain a faster walking pace.
Middle-aged people: This age group begins to pay attention to the prevention of joint diseases. Incorporate less intense but muscle-building activities, such as yoga or tai chi, to help maintain joint flexibility and muscle strength to maintain walking speed.
Seniors: For older friends, the key to maintaining walking speed is to increase balance and prevent falls. Leg strength and balance can be improved through standing exercises, leg raises, and other exercises.
Practical advice
Moderate Exercise:
Set for at least 150 minutes a week of moderate-intensity aerobic activity, such as brisk walking.
Add more than two days of muscle strength training to focus on the muscle groups of the thighs, hips, and abdomen, which are important muscle areas when walking.
Eat a balanced diet:
Consume enough protein to support muscle building and repair. High-protein foods include fish, meat, legumes, and dairy products.
Make sure your diet contains enough calcium and vitamin D to strengthen your bones and prevent osteoporosis.
Regular health check-ups:
Regular check-ups can detect health problems that affect walking speed, such as arthritis or cardiovascular disease, early.
Talk to your doctor about the right exercise plan and dietary modifications.
Daily precautions and exercise suggestions
Balance training: Practice several times a day, such as standing on one foot, with the help of a chair or table to maintain balance when needed.
Strength training: Use dumbbells or body weights for leg strength training, such as squats and back leg lifts, at least twice a week.
Home safety: Make sure your home's walkways are clear, well-lit, and the ground is flat to reduce the risk of falls.
