Illustration of the Means and Standard Error of <i>δD</i> for the three conditions across the two days.

<p>Significant differences occurred between all three tasks (p<0.001), but not within conditions.</p

Three dimensional view of the acceleration data in m•s⁻² illustrating the path of the state vector and cutting point to determine the start and end of a loop.

<p>Depicted is the side view of the area A (in blue) defining the start and the end of a cycle. All traces of the state vector must pass through and be perpendicular to the rectangle.</p
