Final answer:
The swing phase of one full gait cycle of one limb in walking is approximately 40%.
Step-by-step explanation:
The swing phase of one full gait cycle of one limb in walking makes up approximately 40% of the cycle.
In the swing phase, the leg is not in contact with the ground and moves forward, allowing the foot to clear the ground and prepare for the next step.
This percentage may vary slightly depending on the individual's walking speed and gait pattern, but generally, the swing phase accounts for about 40% of the gait cycle.
