Original Article
<div style="text-align: justify;"><strong>Background:</strong> Although maximal sprint speed (MSS) and the anaerobic speed reserve (ASR) provides valuable information about the speed profile of athletes, these parameters fall short of providing important information about sub-maximal metabolic thresholds. The only field test that can offer an estimate of a sub-maximal metabolic threshold is the 3-minute all-out test for running (3MT) which delivers three parameters of interest: the critical speed (CS), fatiguability constant (D’), and 3MT-specific maximal running speed (MS<sub>3MT</sub>).<br>
<strong>Objectives:</strong> We offer an alternative to the ASR, termed the ‘functional’ speed reserve (FSR), and therefore the purpose of this study was two-fold: firstly to compare MSS to MS<sub>3MT</sub> and FSR to ASR, and secondly, to determine the correlations between ASR, FSR, and D’.<br>
<strong>Methods:</strong> Thirty-two participants volunteered for the study (age: 22.50 <em>±</em> 4.32 years; height: 1.67 <em>±</em> 0.78 m; body mass: 66.58 <em>±</em> 11.30 kg) and completed a graded exercise test (GXT), 3MT, and 40-m sprint test following familiarisation bouts for each test.<br>
<strong>Results:</strong> MSS and MS<sub>3MT</sub> were strongly correlated (r=0.93, p<0.001). The ASR and FSR were also strongly correlated (r=0.77, p<0.05), with the FSR also showing a strong correlation with D’ (r=0.77, p<0.05).<br>
<strong>Conclusion:</strong> The 3MT provides a viable, arguably more ecological alternative to the ASR (i.e. FSR), and provides additional parameters such as CS, D’, and MS<sub>3MT</sub>. Field testing based on the 3MT can offer coaches and athletes unique performance insights and tools to effectively program and prescribe training interventions.</div>
