Abstract

The aims of this study were to analyse the optimal cadence for peak power production and time to peak power in bicycle motocross (BMX) riders. Six male elite BMX riders volunteered for the study. Each rider completed 3 maximal sprints at a cadence of 80, 100, 120 and 140revs·min-1 on a laboratory Schoberer Rad Messtechnik (SRM) cycle ergometer in isokinetic mode. The riders’ mean values for peak power and time of power production in all three tests were recorded. The BMX riders produced peak power (1105± 139W) at 100revs·min-1 with lower peak power produced at 80revs·min-1 (1060± 69W), 120revs·min-1 (1077± 141W) and 140revs·min-1 (1046± 175W). The lowest time of power production was attained at 120revs·min-1 in 2.5± 1.07s. Whilst cadence of 80revs·min-1 (3.5 ± 0.8) 100revs·min-1 (3.00 ± 1.13) and 140revs·min-1 (3.50 ± 0.88) all recorded a higher time of power production. The results indicate that the optimal cadence for producing peak power and reducing the time to peak power is attained at a comparatively low cadence for a cycling sprint event. These findings will both enable riders to select optimal gear ratios and have an impact on training focus.
