Duke University researchers found that the rapid walking speed of 45-year-olds can be used as an indicator of the aging of their brains and bodies.
The study published on Friday in the JAMA Network Open journal showed that slower goers were shown to have "accelerated" aging through several measures, while the lungs, teeth, and immune system were in worse shape than the humans went faster.
The data came from a long-term study of nearly 1,000 subjects born in a single year in New Zealand. According to the study, the 904 research participants in the current study were tested, interviewed and measured.
The researchers also found that cognitive testing in people aged three, including IQ, motor skills, and emotional control, could predict their walking speed at the age of 45.
Recent brain studies showed that slower goers tended to have lower total brain volume, lower mean cortical thickness, lower brain surface, and higher incidence of smaller white matter lesions. [1
