Abstract

The aim of this study was to ascertain the variation in elite male BMX cyclists’ peak power, torque and time of power production during laboratory and fieldbased
testing. Eight male elite BMX riders volunteered for the study and each rider completed 3 maximal sprints using both an SRM ergometer in the laboratory, and a portable SRM power meter on an Olympic standard indoor BMX track. The results revealed a significantly higher peak power (p = < 0.001, 34 ± 9 %) and reduced time of power production (p = < 0.001, 105 ± 24 %) in the field tests when compared to laboratory derived values. Torque was also reported to be lower in the laboratory tests, but not to an accepted level of significance (p = 0.182, 6 ± 8 %).These results suggest that field based testing may be a more effective and accurate measure of a BMX rider’s peak power, torque and time of power production.
