How fast you walk in midlife may provide insight into your future physical and mental fitness. Researchers from Duke University in North Carolina and the University of Otago in New Zealand evaluated data from more than 1,000 male and female participants, who were assessed at intervals from birth to age 45 on factors including physical function, gait speed, aging pace and neurocognitive function.
Data analysis showed that participants with slower gait speed at age 45 also had poorer physical function, more cognitive decline from childhood to adulthood, poorer cognitive functioning and more-accelerated aging than those who had faster gait speeds. Study authors noted that gait speed is a robust predictor of dementia and may be a useful measure in trials aimed at preventing its onset. More research is needed.
