Force tracings from a representative subject.

<p><b>Panel A:</b> Raw force trace depicting the data points used for calculation of the peak force (single *) and force impulse (shaded grey area) <b>Panel B:</b> Raw force trace during constant intensity handgrip exercise at target force of 10%>fCF_{peak force}. Arrow indicates first of three consecutive contractions where target force was not achieved, and represents the time at which exhaustion occurred.
