What occurs to double support time as walking speed decreases?

When walking speed decreases, double support time increases. Double support time refers to the period during which both feet are on the ground while walking. At slower speeds, individuals tend to have a longer duration of double support to maintain stability and balance. This is because the body needs more time to transition between phases of the gait cycle, allowing for greater stability.

As people walk faster, they typically spend less time in double support as their gait becomes more efficient and they are able to transition more quickly between the phases of walking. Consequently, as walking speed diminishes, the need for stability results in an increased double support period to compensate for the slower movement, thus supporting the need for balance and coordination.
