Boosting Strength in Old Age

Are you hoping to enhance your strength as you age? You might want to consider picking up your walking pace a bit.

Recent findings from the University of Chicago indicate that walking a tad faster can significantly bolster physical function in elderly individuals who are frail or at risk of becoming frail.

This is important because frailty can lead to a higher likelihood of falls, injuries, hospitalizations, and can even affect independence and life expectancy. While we can’t avoid aging, we can address frailty.

Current estimates suggest that between 4% and 16% of Americans over 65 are classified as frail, with an additional 44% categorized as “prefrail.”

As Dr. Daniel Rubin, the study’s lead author, points out, many people who haven’t experienced frailty can’t fathom the struggle of everyday tasks like grocery shopping without feeling exhausted.

Walking has long been recognized as a gentle yet effective form of exercise for older adults, encouraging both mobility and health.

However, Rubin and his team were keen to explore this further, so they decided to take action.

They gathered a cohort of 102 seniors, averaging 79 years old, from 14 retirement communities—most of whom were women showing signs of vulnerability.

The participants were split into two groups. Both walked for 45 minutes three times a week, including warm-up and cool-down periods.

One group walked at a “relaxed and comfortable” pace, while the other was encouraged to walk “as fast as safely possible.”

After four months, those in the faster group had reached an average of about 100 steps per minute, compared to approximately 77 steps per minute for the slower group.

The faster walkers showed notable improvements, especially on a widely-used six-minute walking test that measures overall physical function.

For frail seniors, covering an additional 30 meters in that six minutes indicated a significant boost in their ability to handle daily activities.

About 65% of the fast walkers met the benchmark compared to just 39% of those who walked at a leisurely pace.

Interestingly, it didn’t take drastic changes to see results. Analysis revealed that increasing walking speed by just 14 steps per minute from their usual rhythm led to the most considerable improvements.

Rubin noted that even moderate walking had beneficial effects on participants. However, increasing the pace by that 14 steps per minute could yield even better outcomes for those who are capable.

The Hidden Risks of Frailty

Frailty isn’t merely about feeling sluggish; it’s a clinical syndrome that complicates recovery from injuries and illnesses.

If you notice at least three of the following warning signs, you might be considered frail:

• Unintentional weight loss of over 10 pounds in the past year
• Difficulty standing without help or weak grip strength
• Feeling tired, even with simple tasks taking extra effort
• A low activity level, even in hobbies or household activities
• Slow walking speed, typically taking 6-7 seconds or more to walk 15 feet

Fortunately, frailty can be addressed. Experts agree that regular physical activity, proper nutrition, and managing health conditions can help delay, prevent, or even reverse frailty.

Improving Your Walking

Looking to strengthen your health? Start by determining your walking cadence—how many steps you take per minute. This will serve as a baseline for improvement.

Rubin suggests trying to add 5-10 steps per minute to whatever pace feels comfortable for you.

To keep a consistent rhythm, he recommends using a metronome app, which can help maintain a steady beat with your steps.

“Ideally, older adults will find this a practical way to boost their walking intensity, leading to a longer and more fulfilling life,” he added.
