Cross-validation of the 20- versus 30-s Wingate anaerobic test

Abstract

The 30-s Wingate anaerobic test (30-WAT) is the most widely accepted protocol for measuring anaerobic response, despite documented physical side effects. Abbreviation of the 30-WAT without loss of data could enhance subject compliance while maintaining test applicability. The intent of this study was to quantify the validity of the 20-s Wingate anaerobic test (20-WAT) versus the traditional 30-WAT. Fifty males (mean +/- SEM; age = 20.5 +/- 0.3 years; Ht = 1.6 +/- 0.01 m; Wt = 75.5 +/- 2.6 kg) were randomly selected to either a validation (N = 35) or cross-validation group (N = 15) and completed a 20-WAT and 30-WAT in double blind, random order on separate days to determine peak power (PP; W kg(-1)), mean power (MP; W kg(-1)), and fatigue index (FI; %). Utilizing power outputs (relative to body mass) recorded during each second of both protocols, a non-linear regression equation (Y (20WAT+10 )= 31.4697 e(-0.5)[ln(X (second)/1174.3961)/2.6369(2)]; r (2) = 0.97; SEE = 0.56 W kg(-1)) successfully predicted (error approximately 10%) the final 10 s of power outputs in the cross-validation population. There were no significant differences between MP and FI between the 20-WAT that included the predicted 10 s of power outputs (20-WAT+10) and the 30-WAT. When derived data were subjected to Bland-Altman analyses, the majority of plots (93%) fell within the limits of agreement (+/-2SD). Therefore, when compared to the 30-WAT, the 20-WAT may be considered a valid alternative when used with the predictive non-linear regression equation to derive the final power output values.

Anaerobic metabolism during short all-out efforts in tethered running: Comparison of energy expenditure and mechanical parameters between different sprint durations for testing

“…The volunteers were explained the need to not pace themselves, and strong verbal encouragement was given throughout the entire efforts in order to perform it in their maximum performance. P max in ≤ 10 s durations was already shown to be higher than in AO30s [10, 15], but previous studies comparing 20 s to 30 s durations could not confirm these results since it divided the 30 s effort [31] or used double-blind designs [32]. If an unconscious pacing strategy happens in an AO30s, it could not be confirmed for AO20s in the current investigation, based in the comparisons to AO10s data.…”

The Measurement of Maximal (Anaerobic) Power Output on a Cycle Ergometer: A Critical Review

“…and subsequent subject apprehension have been reported to occur after the Wingate test. The mean power output during the 30 seconds of a Wingate test was highly correlated with the mean power measured during the first 20 seconds of the same exercise [96], which was confirmed by a study comparing 20- and 30-second all-out tests performed during different sessions [97]. An exponential regression equation was proposed to predict the performance in a “normal” Wingate test from the data of a 20 second all-out test.…”

LEARN 2 MOVE 7-12 years: a randomized controlled trial on the effects of a physical activity stimulation program in children with cerebral palsy

“…Anaerobic capacity will be assessed with the 20-second Wingate anaerobic test (WAnT20) (Wingate Software V1, Lode B.V., Groningen, the Netherlands), adapted from the original 30-second test[40], on the same bicycle ergometer. During a 4-minute warming-up, the children will perform two or three 5-second sprint practise trials to determine the optimal torque for the WAnT20, by varying the braking force (Nm) between the practise trials.…”
