Abstract

The purpose of this study was to determine resistance loads which elicit maximal values of power output (PO) during performance of the Wingate test (WT). Nineteen male subjects (mean age, 25.1 yrs; mean V02 max, 3.52 l/min) performed multiple WTs in a random order at resistances ranging from 3.23 to 6.76 joules/pedal rev/kg BW. Tests were carried out on a Monark cycle ergometer modified to permit instantaneous application of resistance. Revolutions were determined by a computer interfaced frequency counter. The mean resistances eliciting the highest peak power (PP) and mean power (MP) outputs were 6.65 and 5.53 joules/pedal rev/kg BW, respectively (average of 5.59 joules/pedal rev/kg BW). Both PP and MP were significantly higher (15.5 and 13.0, respectively) using a resistance load of 5.59 compared to the Wingate setting of 4.41 joules/pedal rev/kg BW. The test-retest reliability for PP and MP ranged between 0.91 and 0.93 at both resistance loads. Body weight and thigh volume did not significantly estimate the individual restistances eliciting maximal POs. The data suggest that resistance be assigned according to the subjects BW but consideration be given to increasing the resistance from that presently used in various laboratories. Verf.-Referat
