EFFECT OF HIP ORIENTATION ON WINGATE ANAEROBIC POWER OUTPUT
Keywords: cycling, recumbent, hip position, peak power
AbstractThe effect on anaerobic power output of Hip Orientation Angle (HOA, angle of hip joint to bottom bracket relative to horizontal) while maintaining a constant Body Configuration Angle (BCA, included angle between torso, hip, and bottom bracket) and maximum hipto- pedal distance was examined. In this way, changes in power output could be attributable to the altered pull of gravity on the lower extremity. Nineteen male recreational cyclists with no recent recumbent cycling experience completed 30 s Wingate tests in three recumbent positions (HOA of -20, -10, and 0°) and the standard cycling position (HOA = 75°), all with a 130° BCA. Neither peak, average, or minimum power were significantly different across all positions nor was fatigue index (p < 0.01). These findings suggest that anaerobic power is not altered by hip orientation.
