Final answer:
The stance phase of walking accounts for 60% and the swing phase 40% of the gait cycle. For running, the time in stance decreases and swing increases with higher speeds but exact percentages require specific data.
Step-by-step explanation:
In human gait cycle during walking, the stance phase comprises about 60% of the cycle, while the swing phase accounts for the remaining 40%. This reflects the time when one foot is in constant contact with the ground (stance) versus when it's off the ground moving forward (swing). In contrast, the gait cycle percentages for running vary greatly due to differences in speed, but there is a general trend that as speed increases, the stance phase decreases.
Unfortunately, without specified data for running, we can't provide an exact percentage for the stance and swing phases like we can for walking. However, we know for running, at higher speeds, runners spend more time in the air (swing phase) and less time with their foot on the ground (stance phase) compared to walking.
