Abstract
The validity of the Running-based Anaerobic Sprint Test (RAST) was investigated to evaluate the anaerobic power performance in comparison to Wingate test in cycling athletes. Ten mountain-bike male cyclists (28.0±7.3 years) randomly performed Wingate Test and RAST with two trials each. After several anthropometric measurements, peak power (PP), mean power (MP) and fatigue index (FI) for RAST and Wingate Test were analyzed using Student's paired t-test, Pearson's linear correlation test (r) and Bland and Altman's plots. Results showed that, with the exception of FI (33.8±4.6% vs. 37.8±7.9%; r=0.172), significant differences were detected between the Wingate and RAST tests with regard to PP and MP. Although there was a strong correlation for PP and MP, or rather, 0.831 and 0.714 respectively, agreement of analysis between Wingate and RAST protocols was low. The above suggested that RAST was not appropriate to evaluate the performance of anaerobic power by Wingate test in cycling athletes.

There was a strong correlation between Wingate test and Running-based Anaerobic Sprint Test (RAST) for peak power (PP) and mean power (MP) in power units (W)
Wingate test is applied and interpreted, it requires a set of resources, such as a cycle ergometer, computer and specific software that would detect the bicycle signal and, the analysis of results
Summary
Bicycles are some of the most popular vehicles for competitions, sports and transport. Duration of sports competitions affects aerobic metabolism, anaerobic pathways have great influence during certain periods of cycling. Anaerobic ability is important for performance in competitions since adenosine triphosphate re-synthesis speed becomes a variable of great relevance during critical moments when maximum and intense power is required (Nummela, Alberts, Rijntjes, Luhtanen, & Rusko, 1996). The literature abounds with a wide variety of protocols for cycling ergometer and running test to evaluate anaerobic performance. The Wingate test is considered the most common test to evaluate anaerobic cycling performance (Bar-Or, 1987) and many studies have used the Wingate test to assess the anaerobic metabolism of multi-sprint sports athletes (Bencke et al, 2002; Davis, Brewer, & Atkin, 1992). Within the Wingate test protocol, PP represents the highest average power output over a 3- to 5-second period, MP is the average power maintained throughout the six 5 s segments and FI is the amount of the decline in power during the test, expressed as a percentage of peak power (Beneke, Pollmann, Bleif, Leithauser, & Hutker, 2002)
