    Ozkaya, O; Colakoglu, M; Fowler, D; Kuzucu, OE; Colakoglu, S
    The Wingate Anaerobic Test is the most common method used to evaluate explosive power and anaerobic capacity. The Wingate Anaerobic Test performed on an elliptical trainer (WAnTet) may be more accurate than the Wingate Anaerobic Test performed on a cycle ergometer (WAnTc) since larger muscle group recruitment with the WAnTet results in higher anaerobic output. The purpose of this study was to evaluate and compare peak power ( PP), average power (AP), fatigue index (FI%) and delta lactate responses (Delta La) between WAnTet and WAnTc in healthy male university athletes. In our test subjects, (n = 40; 21 +/- 2 years old), PP ( 1463 +/- 238 vs. 879 +/- 162 watts) and AP ( 1127 +/- 191 vs. 649 +/- 82 watts) for the WAnTet were higher when compared to the WAnTc ( p < 0.001). FI%s of WAnTet and WAnTc were similar ( 49.8 +/- 10.3% and 46.9 +/- 8.3%, respectively; p = 0.054) but. La values were higher for WAnTet than for WAnTc (12.9 +/- 1.7 mM vs. 9.2 +/- 1.5 mM, respectively; p < 0.001). Using an elliptical trainer, rather than a traditional cycle ergometer, results in a more accurate measure of anaerobic power when Wingate Anaerobic Testing is performed.

    Wingate anaerobic testing with a modified electromagnetically braked elliptical trainer. Part I: Methodological considerations
    Ozkaya, O; Colakoglu, M; Ozgonenel, O; Fowler, D; Colakoglu, S; Tekat, A
    The aim of this study was to modify an elliptical trainer and determine a suitable test load with it in order to perform Wingate anaerobic testing (WAnTet). Modifications were made to an electromagnetically braked elliptical trainer. Study participants were forty-eight physically active male college athletes ( mean age 20 +/- 1 years). Two pilot studies (n = 8) were administered to determine electrical signalling errors and to select the range of potentially suitable test loads ( between 0.5 to 1.3 watt/kg). The 1.0 watt/kg WAnTet load was determined to be the most suitable for WAnTet applications amongst 0.8 to 1.1 watt/kg loads ( n = 40; p < 0.05). Test-retest results using the 1.0 watt/ kg load for peak power ( PP) ( 1477 +/- 258 and 1484 +/- 271 watts), average power (AP) ( 1134 +/- 209 and 1120 +/- 208 watts), fatigue index ratio (FI%) ( 49 +/- 10% and 49 +/- 10%) and change in lactate levels ( 12.6 +/- 1.7 and 12.4 +/- 2.1 mM) were highly correlated (r: 0.94, 0.94, 0.80 and 0.74, respectively; p < 0.001). An electromagnetically braked elliptical trainer may be used to measure anaerobic power and anaerobic capacity of athletes and may be substituted for the usual Wingate anaerobic test performed on a cycle ergometer.
