Frailty affects millions of older adults worldwide, with 24% of the global population facing issues related to this condition. Frailty increases the risk of cognitive impairment, dementia, and falls. However, a new study suggests that walking at a slightly faster speed than usual can improve physical function in frail or high-risk individuals.
Researchers developed a smartphone app designed to accurately measure walking pace, making it easier for older adults to increase their speed. The study recruited 102 participants aged 60 and above who were prefrail or frail. Participants were assigned to either a casual speed walking group or a high-intensity walking group.
The results showed that those in the high-intensity walking group experienced significant improvements in physical function, with a modest increase of 14 steps per minute. This suggests that even small increases in walking intensity can lead to meaningful benefits for frail or prefrail older adults.
Daniel Rubin, MD, lead author of the study, explains that “walking is accessible, low-cost, and adaptable to many fitness levels.” To maximize health benefits, walking should be done with enough intensity. The 14-step threshold provides a clear target for older adults to increase their intensity.
The Walk Test app, developed by Rubin’s team, measures accurate walking cadence and is designed to be user-friendly. While not yet publicly available, the researchers plan to make it accessible once they secure additional funding.
Experts agree that exercise training can expand physiologic potential in frail older adults. Jonathan Bean, MD, MPH, notes that brisk walking may be an additional mode of training to optimize mobility skills. Bert Mandelbaum, MD, emphasizes the importance of exercise in improving bone density, balance, and cognitive function.
The study’s findings highlight the benefits of increased physical activity for frail older adults, with potential implications for optimizing mobility and reducing disability. As one expert put it, “longevity starts now,” and even small changes in lifestyle can have a positive impact on overall health.
