Final answer:
The typical ratio of the swing phase to the entire gait cycle in race walking is 60-70%, with the swing phase being when the foot is off the ground and moving forward.
Step-by-step explanation:
The typical ratio of the swing phase to the entire gait cycle in race walking is 60-70%. The swing phase is the part of the gait cycle when the foot is off the ground and moving forward. In contrast, the stance phase is when the foot is in contact with the ground. Race walking, as a competitive sport, has specific rules that differentiate it from running, such as the requirement that one foot must always be in contact with the ground. This rule influences the ratio of the swing phase within the gait cycle, which is markedly higher in race walking as compared to running, where the swing phase can represent a smaller percentage of the gait cycle.
