The walking speed of a person may help the body function better, a
study stated which has shown that people who walk slowly at 45 degrees
angle have more accelerated ageing than those who walk fast. According
to the research, slower walkers have a greater reduction in brain volume
and also have low balance and grip strength than those who walk at a
normal pace.
The study published in JAMA Network Open that
assessed health data of more than 900 New Zealanders over a period of 40
years (since they were around three years old) used GAITRite Electronic
Walkway - a system that provides gait analysis and identifies anomalies
- to categorise them into slowest (average 1.21 meters per second),
fastest (average 1.75 m/s), and those who walked at a normal pace
(average 1.50 m/s).
The findings of the research that also
assessed 19 biomarkers, including body mass index (BMI), waist-to-hip
ratio, cholesterol levels, white blood cell count, gum health, and
cardiorespiratory fitness, suggested those with the slowest walking
speed showed accelerated ageing and a reduction in total brain volume,
meaning that walking speed affects both physical as well as cognitive
health.
The results showed there was a 16-point IQ difference
between the fastest and the slowest walkers. Slow walkers also appeared
significantly older than those who walk faster and scored worse on
balance and grip measuring test, said lead researcher Line Rasmussen
from the Duke University.
