Test–retest reliability of a 3-min isokinetic all-out test using two different cadences

The 3-minute all-out cycling test is sensitive to changes in cadence using the Lode Excalibur Sport ergometer

“…. In contrast to Vanhatalo et al (2008), Dekerle et al (2014) found that WEP was significantly increased when tested at a higher cadence. In a similar study, deLucas et al (2014) found a significant reduction in EP on the adoption of a higher cadence (100 vs. 60 rev•min -1 ) but no differences in WEP were observed between cadences.…”

“…It was also found that WEP was significantly higher on the adoption of a lower cadence and lower when using a higher cadence. Dekerle et al (2014) also found that cadence selection affected EP when carried out in isokinetic mode, with a significantly lower EP observed when tested at 100 rev•min -1 compared to 60 rev•min -…”

“…Vanhatalo, Doust and Burnley (2007) found that the 3-minute all-out cycling test provided near identical estimations of CP and similar, albeit slightly lower, estimations of Wʹ. However, more recent studies have found that EP overestimates CP by approximately 5-12%, with WEP significantly underestimating Wʹ ( During the studies by Dekerle et al (2014) and Karsten et al (2014), the 3-minute allout cycling test was carried out using a fixed cadence of between 60-100 rev•min -1 (isokinetic mode) rather than against a fixed resistance (linear mode) as used by Vanhatalo et al (2007). This difference in testing mode may help to explain why both Dekerle et al (2014) and Karsten et al (2014) found that the 3-minute all-out test overestimates CP.…”

However, a more recent study by Wright et al (2017) evaluated CP using both isokinetic and linear modes, with results suggesting that EP determined from the linear mode significantly overestimated CP.…”

Methodological Approaches and Related Challenges Associated With the Determination of Critical Power and Curvature Constant

“…With regards to the reliability of EP and WEP, both parameters show a similar degree of reliability to those derived from the conventional testing approach. Specifically, the reliability of EP has consistently been shown to be better (CV of 3-7%) than that of the WEP (8-21%) (25,38,58,73).…”
