Instantaneous <i>ODBA</i> plotted against <i>VeDBA</i> using all data from a participant recorded during a full max test.

<p>In this example, as with all other participants, the relationship between <i>ODBA</i> and <i>VeDBA</i> was highly significant (<i>VeDBA</i> = 0.014+0.6418 <i>ODBA</i>, r² = 0.987, P<0.001).</p

An example plot of uptake against <i>ODBA</i> (black circles) and <i>VeDBA</i> (grey triangles) over the duration of the trial following removal of the points above the participant's anaerobic threshold.

Dynamic body accelerations (<i>ODBA</i> – circles, and <i>VeDBA</i> –crosses) from straight- versus skew-mounted accelerometers (for details see text).

<p>Each point denotes a mean value derived from a three-minute trial of a participant moving at one particular speed below the lactate threshold. Data from all participants are included.</p

Heave (continuous line), sway (dotted line) and surge (dashed line) acceleration axes displayed graphically over one stride (from each leg) during walking (i) and running (ii).

Relationship between mean <i>ODBA</i> and mean <i>VeDBA</i> (means taken for each running speed) for a test participant during a max test.

<p>Only data during the period when the participant did not exceed the ventilatory threshold (for definition see text) are included. as with all other participants, the relationship between <i>ODBA</i> and <i>VeDBA</i> was highly significant (<i>VeDBA</i> = 0.014+0.6418 <i>ODBA</i>, r² = 0.987, P<0.001).</p

Predicted difference between straight- and skew-mounted <i>ODBA</i> derived from recordings on a tri-axial accelerometer subjected to equal acceleration in the heave, surge and sway axes as a function of pitch, roll and yaw differences between straight and skew.

<p>Contour lines show 2.5% intervals.</p
