In A Nutshell
- Increasing walking speed by 14 steps per minute boosted the odds of meaningful functional improvement in older adults with frailty.
- Participants who walked “as fast as they safely could” were nearly twice as likely to improve on a standard 6-minute walk test compared to those walking at a casual pace.
- These gains were linked to individual speed increases, not just being in the “intensive” exercise group.
- The findings suggest that tracking walking cadence with simple devices can guide personalized exercise plans in senior care.
CHICAGO — Picking up the pace during a walk might sound like obvious health advice, but for millions of older Americans already showing signs of physical decline, those extra steps per minute could be the difference between maintaining independence and losing it entirely.
Research tracking 102 seniors in Chicago-area retirement communities reveals that increasing walking speed by just 14 steps per minute during exercise dramatically improves physical function in people who are frail or becoming frail. The four-month study found that 65% of seniors who walked “as fast as they safely could” saw meaningful improvements in their ability to walk longer distances, compared to only 39% of those who stuck to a comfortable, leisurely pace.
For context, this means someone who normally walks at 80 steps per minute and bumps it up to 94 steps per minute could see real improvements in their daily physical capacity — the kind that affects whether they can handle grocery shopping, climb stairs, or maintain their independence.
The Growing Problem of Frailty
Frailty affects roughly 15% of Americans over 65 and goes far beyond normal aging. It’s a medical condition marked by unintentional weight loss, constant exhaustion, muscle weakness, slow movement, and low activity levels. Unlike typical age-related changes, frailty creates a dangerous downward spiral where people become less active, which makes them weaker, which makes them even less active.
This cycle dramatically increases the risk of falls, disability, hospitalization, and death. Breaking it has become urgent as America’s population ages rapidly, with researchers scrambling to find interventions that actually work for people who are already physically vulnerable.
Walking programs have shown promise because they address multiple aspects of frailty at once. But figuring out the right exercise “prescription,” that is, how often, how long, and how hard people should walk, has been tricky. That’s especially the case for older adults with heart conditions or those taking medications that affect their response to exercise.

Why Counting Steps Works Better Than Heart Rate
Traditional ways of measuring exercise intensity often fail older adults. Heart rate monitors become unreliable when people take common medications like beta blockers, which prevent heart rates from rising normally during exercise. Asking people to rate how hard they’re working on a scale of 1 to 10 also proves unreliable; many seniors struggle to accurately judge their exertion levels.
Counting steps per minute offers something much simpler and more objective. Anyone can track this using a smartphone or basic fitness watch, and previous research shows that hitting 100 steps per minute typically qualifies as moderate-intensity exercise.
The Chicago study, led by Dr. Daniel Rubin, an associate professor at the University of Chicago, equipped participants with highly accurate accelerometers worn on the thigh throughout each exercise session. These devices recorded every step, allowing researchers to calculate precise walking speeds for each person across the entire four-month program.
The Experiment: Fast Walkers vs. Comfortable Pacers
The 102 participants, averaging nearly 79 years old, represented diverse racial and economic backgrounds from 14 retirement communities. The majority (80%) were women, and all showed signs of being frail or prefrail based on standard medical assessments.
Both groups followed identical schedules: three sessions per week, each lasting 45 minutes with 15 minutes of warm-up and cool-down plus 30 minutes of actual walking. The only difference was in the instructions given to each group.
The “casual speed walking” group was told to maintain a “relaxed and comfortable pace.” The “high-intensity walking” group was encouraged to walk “as fast as they safely could.” All sessions were supervised by trained staff who provided standardized encouragement and safety monitoring.
During the final phase of the program, the results were stark. The high-intensity group averaged 100 steps per minute compared to 77 steps per minute for the casual walkers. More importantly, the faster walkers were far more likely to see meaningful improvements in a standard fitness test called the 6-minute walk test.
The 6-minute walk test measures how far someone can walk in six minutes, which is a strong predictor of overall physical function and independence. For frail older adults, improving by 30 meters or more is considered clinically meaningful, representing real-world differences in the ability to complete daily activities.
When researchers analyzed the data, they found that participants who increased their walking speed by 14 steps per minute from their comfortable baseline had significantly better odds of hitting this improvement threshold. Importantly, when they accounted for individual speed increases, the advantage of being in the “high-intensity” group disappeared entirely, meaning the speed boost itself, not just being told to walk faster, drove the benefits.
The paper did not report any serious injuries, and participants were allowed to rest as needed during sessions. Those breaks didn’t count toward their 30-minute walking target.
The research, published in PLOS One, offers immediate practical applications for assisted living facilities, community centers, and healthcare providers working with older adults. Rather than generic “gentle exercise” programs, facilities could set individualized speed targets based on each person’s comfortable walking pace and use basic activity monitors to track progress toward that 14-step improvement goal.
For the millions of older Americans facing declining physical function, this research provides both hope and a concrete action plan. Maintaining independence may come down to something as measurable and achievable as adding 14 extra steps per minute to regular walks — a remarkably specific target that could help transform how people age in America.
Paper Summary
Methodology
Researchers conducted a secondary analysis of data from a randomized controlled trial involving 102 prefrail and frail older adults (average age 79) living in 14 retirement communities in the Chicago area. Participants were randomly assigned to either a casual speed walking group or a high-intensity walking group. Both groups completed 48 exercise sessions over 4 months, with three 45-minute sessions per week. Each session included 15 minutes of warm-up and cool-down plus 30 minutes of walking. The casual group was instructed to walk at a comfortable pace, while the high-intensity group was told to walk “as fast as you safely can.” All participants wore thigh-mounted accelerometers during sessions to precisely measure walking cadence (steps per minute). The primary outcome was improvement in 6-minute walk test distance of at least 30 meters, considered clinically meaningful for this population.
Results
Participants in the high-intensity walking group achieved significantly higher walking cadences than the casual walking group (100 vs. 77 steps per minute during the final phase). More importantly, 65% of high-intensity walkers showed meaningful improvements in their 6-minute walk test compared to 39% of casual walkers. The researchers found that increasing walking cadence by 14 steps per minute from baseline comfortable pace significantly increased the odds of achieving functional improvement. When individual cadence changes were accounted for, the group assignment effect disappeared, suggesting that the speed increase itself drove the benefits rather than other aspects of the intervention.
Limitations
The study was conducted in retirement communities with motivated volunteers who may not represent all frail older adults. All sessions were supervised by research assistants providing standardized encouragement, making it unclear whether unsupervised participants could achieve similar results. The baseline 6-minute walk distance of approximately 250 meters was well below community norms, highlighting the significantly impaired functional capacity of the study population. The authors noted that all participants were volunteers from retirement communities and were likely motivated, raising the possibility of selection bias.
