start of the phase, <strong>to</strong>uchdown (or foot strike), and its end, <strong>to</strong>e-off. The support phase<br />

starts at <strong>to</strong>e-off and ends at <strong>to</strong>uchdown; at this stage, we will consider its function <strong>to</strong> be<br />

phase will be very short; it will then increase with running speed.<br />
