Quizplus · Accepted Answer

The variability in footfall positions increasing and then decreasing suggests that runners initially rely less on visual feedback, leading to greater variability. As they get closer to the jump board, they rely more on visual feedback to adjust their steps, reducing variability. This pattern aligns with the idea that visual feedback becomes more crucial as the athlete needs to precisely hit the jump board, hence the shift from less to more reliance on visual feedback.
