method_dmax

It applies the <code>Dmax</code> methods: <code>"Dmax"</code>, <code>"ModDmax"</code>, <code>"Exp-Dmax"</code>, <code>"Log-Poly-ModDmax"</code>, and <code>"Log-Exp-ModDmax"</code>.

Set of tools for analyzing lactate thresholds from a step incremental test to exhaustion. Easily analyze
the methods Log-log, Onset of Blood Lactate Accumulation (OBLA), Baseline plus (Bsln+), Dmax, Lactate Turning Point (LTP),
and Lactate / Intensity ratio (LTratio) in cycling, running, or swimming.

method_dmax function

<dl><dt>data_prepared</dt>
<dd>The data retrieved from <code>prepare_data()</code>.</dd>
<dt>sport</dt>
<dd>The sport at which the incremental test was performed. One of <code>cycling</code>, <code>running</code>, or <code>swimming</code>.</dd>
<dt>loglog_restrainer</dt>
<dd>A scalar from 0 to 1 indicating the percentage of the data that you would like to
restrain for fitting the Log-Log method - This is going to be used in the <code>Log-Poly-ModDmax</code> and <code>Log-Exp-ModDmax</code> methods only.
For example, <code>1</code> means no restriction (fits using the whole data), and <code>0.5</code> means that
only the first 50% of the data will be used. Default to <code>1</code>.</dd>
<dt>plot</dt>
<dd>A boolean to indicate whether to generate a plot from each one of the methods.<div class="section" id="fit">
<h3>Fit</h3></div></dd>
The <code>method_dmax()</code> function does not have a <code>fit</code> argument because all the <code>Dmax</code> methods have their own default fitting methods:<ul>
<li>Dmax = 3rd degree polynomial</li>
<li>ModDmax = 3rd degree polynomial</li>
<li>Exp-Dmax = exponential</li>
<li>Log-Poly-ModDmax = 3rd degree polynomial</li>
<li>Log-Exp-ModDmax = exponential</li>
</ul></dl>
