Abstract

The purpose of this investigation was to examine the ability of a windload simulator to reproduce the resistive forces faced by a cyclist during on-road training. The simulator consisted of a mul- tivaned fan enclosed in a ported housing. The levd of resistance could be augmented by increasing the port opening. The oxygen consumption (VO2) of five healthy male subjects was measured under steady state conditions at speeds of 16.1,24.1 and 32.2 km per hour at three intake port openings (1/4, 1/2 and 3/4 open) for each speed. The results were compared to previously reported predicted and actual on-road oxygen consumption values. Two- way ANOVA showed that increases in speed and opening elicited significant increases in VO2; and a significant interaction existed between speed and opening. Post hoc comparisons of VO2showed all speeds and openings to be different (p < 0.05). When compared with previously reported on-road values, the resistance settings on the windload simulator showed the ability to produce differing levels of VO2within the ranges of those encountered during on-road training. The results indicate that the windload trainer can accurately reproduce resistive forces within the range of actual on-road training.
