Abstract
This study compared power output during a 30-second max- imal cycle ergometry test using a resistance that was deter- mined to yield maximal 10-second power output (Windsor method) with power output generated using the more tra- ditional methods of resistance-setting determination (0.735 N·kg21 body mass (Wingate method) or 30-second power output at 49 N (Alberta method)). Sixteen men (mean 6 SD: 21.6 6 1.0 years of age, VO2 5 48.7 6 2.3 ml·kg 21 ·min 21 ) volunteered as subjects. Peak 1-second and best consecutive 5-second power outputs were not significantly greater across the 3 methods. Mean power output was significantly (p , 0.05) greater using the Windsor (621.0 6 18.2 W) or Wingate (588.8 6 23.5 W) resistance as compared with the Alberta (464.7 6 44.3 W) resistance. Fatigue index (FI) was greater using the Alberta method (42.67 6 4.21%) than when using either the Windsor (27.16 6 1.63%) or Wingate (28.98 6 3.05%) methods. These results indicate that the Alberta method fails to produce a resistance that yields maximal power output. Furthermore, the lack of significant difference between the Windsor and Wingate methods suggests that although the Windsor method results in a more ''individu- alized'' resistance, the Wingate method is equivalent with respect to maximal power output attainment and surpasses the Windsor method when one takes into consideration the time and effort involved in determining the Windsor resis- tance.
