La intensitat del test sobre SB fou determinada mitjançant cadència, començant per 30 impulsos/min i augmentant 3 impulsos/min cada minut fins a l’esgotament.

However, the specificity of laboratory skating assessments remains to be established.</p> <p class="elsevierStylePara"> Purpose: This study intended to assess the test-retest reliability of an incremental test performed on a slide board (SB), and its validity compared with a cycling protocol in order to determine aerobic performance indices in speed skaters.</p> <p class="elsevierStylePara"> Methods: Ten competitive inline speed skaters performed two incremental tests on an SB and one cycling incremental test. The intensity of SB test was determined by cadence, starting at 30 push-offs/min and increasing by three push-offs/min each minute, until volitional exhaustion. Maximal and submaximal values related to the anaerobic threshold (AT) of oxygen uptake (VO<span class="elsevierStyleInf">2</span>), pulmonary ventilation (VE), respiratory exchange (RER), heart rate (HR), rating of perceived effort (RPE), cadence (CAD), and blood lactate concentration ([Lac]<span class="elsevierStyleInf">max</span>) were measured.</p> <p class="elsevierStylePara"> Results: No significant differences were found in any of the variables between testretest on SB. High relative (ICC > 0.9) and absolute reliability (typical error of measure as CVTEM < 3.5%) were found for VO<span class="elsevierStyleInf">2max</span>, HR<span class="elsevierStyleInf">max</span>, [Lac]<span class="elsevierStyleInf">max</span>, CAD<span class="elsevierStyleInf">max</span>, VO<span class="elsevierStyleInf">2AT</span>, CAD<span class="elsevierStyleInf">AT</span> and RPE<span class="elsevierStyleInf">AT</span>.
