Bouncing Back: The Role of Physical Resilience in Aging Well

Have you ever noticed how people who take care of themselves tend to recover from illness and injury more quickly than those who don’t? Have you ever wondered why those people bounce back quickly from physical setbacks while others struggle? The key often lies in their level of physical resilience.

What is Physical Resilience?

As we age, the concept of "adding life to our years" becomes increasingly significant. Physical resilience refers to the body’s ability to adapt to challenges, maintain stamina and strength, and recover quickly and efficiently. It’s a person’s ability to function and recover when faced with illness, accidents, or other physical demands. Research shows that physical resilience plays an important role in healthy aging. It not only enhances our capacity to bounce back from health setbacks, but also contributes to a richer, more fulfilling life.

Consider my 70-year-old friend Holly who recently fell while walking and broke her arm. She didn’t fall because she’s frail; she fell because she tripped on a rock. Her Physical Resilience Score"—which is used to determine an individual's level of resilience based on factors like muscle strength, balance, and endurance—is fairly high because she walks most days, usually eats well, and prioritizes sleep. Her doctor told her that her injuries likely weren’t more severe, and she's likely to recover faster, because of her healthy lifestyle. This is an example of physical resilience. Holly’s habits and lifestyle have contributed to a more robust and adaptable body, enabling her to avert more serious injury, bounce back faster, and heal more efficiently.

Why Do We Lose Physical Resilience as We Age?

Several factors contribute to the decline in physical resilience with age:

• Muscle Loss: Sarcopenia, or age-related muscle loss, reduces strength and endurance.

• Decreased Bone Density: Osteoporosis can lead to frailty and a higher risk of fractures.

• Reduced Cardiovascular Efficiency: The heart and blood vessels become less efficient, affecting overall stamina.

• Slower Metabolism: Aging slows down the metabolic rate, making recovery from physical stressors slower.

Actionable Steps to Improve Physical Resilience

Let’s face it: even if we take good care of ourselves, stuff happens. No matter how well we plan and look after ourselves, we can still take an unexpected tumble or get an unexpected health diagnosis. As we grow older, things like this can have life-altering consequences. And while we can’t stop the clock, we can slow it down by improving our physical resilience. Here’s how:

• Regular Exercise: Research in the Journal of Public Health examined the relationship between physical activity and resilience among older adults. The findings suggest that higher levels of physical activity are associated with greater resilience. Engage in a mix of aerobic, strength, balance, and flexibility exercises. The CDC recommends at least 150 minutes of moderate-intensity aerobic activity and muscle-strengthening activities on two or more days per week.

  • Aerobic Exercise: Walking, swimming, or cycling to improve cardiovascular health.

  • Strength Training: Lifting weights or resistance band exercises to build muscle.

  • Balance Exercises: Yoga or tai chi to enhance stability and prevent falls.

  • Flexibility Training: Stretching exercises to maintain range of motion.

• Nutrition: A balanced diet rich in proteins, vitamins, and minerals supports muscle and bone health, which are essential for physical resilience. Avoid ultra-processed junk foods and soft drinks.

• Hydration: Staying well-hydrated aids in overall physical function and recovery. But it may be surprising to learn that water intake is an individualized number. So how much fluid does the average, healthy adult living in a temperate climate need? The U.S. National Academies of Sciences, Engineering, and Medicine determined that an adequate daily fluid intake is about 15.5 cups (3.7 liters) of fluids a day for men and about 11.5 cups (2.7 liters) of fluids a day for women. These recommendations cover fluids from water, other beverages, and food. Certain health conditions, medications, activity level, and ambient temperature influence total daily water intake. Older adults are more susceptible to dehydration, which is associated with adverse health outcomes.

• Adequate Rest: Ensure sufficient sleep and rest to allow the body to recover and regenerate. According to the National Sleep Foundation, adults between the ages of 18 and 64 should aim for seven to nine hours of nightly sleep. If you’re older than 65, you may need a little less—seven to eight hours is recommended.

• Manage Stress: Incorporate stress-reducing practices such as meditation, deep breathing, or hobbies to maintain overall well-being.

Importance of Physical Resilience in Aging

Maintaining physical resilience as we age becomes crucial for several reasons:

• Faster Recovery: Older adults with high physical resilience can bounce back more quickly from injuries, surgeries, and illnesses.

• Improved Quality of Life: Physical resilience helps maintain independence and functionality, contributing to a better quality of life.

• Reduced Risk of Chronic Diseases: Resilient individuals are better at managing and preventing chronic conditions.

Conclusion

Building and maintaining physical resilience are essential for aging well. By focusing on regular exercise, proper nutrition, hydration, sleep, and stress management, older adults can enhance their ability to bounce back from physical setbacks. Embracing these habits not only helps in recovering from injuries and illnesses faster, but also contributes to a better quality of life and prolonged independence.

Remember, it's never too late to start building physical resilience and reaping the benefits of a more robust and resilient body.
