This study examined the specificity of V̇0₂ max in 10 male endurance-trained runners and 10 male endurance- trained cyclists who performed continuous multistaged exercise tests on a "racing" bicycle ergometer (RE), a standard bicycle ergometer (SE), and a running treadmill (RT). Purposes of this study were to (a) determine if RE elicited a higher V̇0₂ max in competitive cyclists as compared to either SE or RT; (b) evaluate how non-bicycle-trained, but well-conditioned athletes (trained runners) performed on the three V̇0₂ max tests; and (c) compare cyclists' and runners' performance on these tests and in so doing investigate the influence of training specificity on V̇0₂ max. RE was performed at 90 r.p.m. using a mechanically-braked Monark ergometer modified with drop handlebars, racing seat, and pedals equipped with toe clips and straps. Racing cleats were worn by all subjects. SE was performed at 50 r.p.m. on the same Monark ergometer without equipment modifications or special racing cleats. A split-plot 2 X 3 Anova with repeated measures followed by Tukey's post hoc analysis indicated a significant difference (p̲ < .001) in V̇0₂ max between exercise modalities (X̅ RT=67.26 ml•kg•min-¹; X̅ RE=62.69 ml•kg•min-¹; X̅ SE=62.40 ml•kg•min-¹). Runners achieved a significantly higher V02 max on RT (67.34 ml•kg•min-¹) as compared to RE (60.64 ml•kg•min-¹) or SE (60.45 ml•kg•min-1). Cyclists obtained their highest V02 max on RT (67.17 ml•kg•min-¹), but this value was not significantly different from RE (64.74 ml•kg•min-¹) or SE (64.35 ml•kg •min-1). Maximal ventilation (V̇[sub E] max), maximal heart rate (HR max) and maximal respiratory exchange ratio (RER max), were not significantly different between training groups or modalities. Both groups X̅ performance time, and X̅ obtained maximal workloads were significantly greater during RE as compared to SE. Runners worked significantly longer (p̲ < .05) during treadmill exercise than did cyclists. It was concluded that modifications to SE which created RE did not effectively increase V̇0₂ max, although the RE protocol appeared to facilitate a greater cycling economy. Runners demonstrated a specific training adaptation for running, which did not carry over to cycling whereas cyclists demonstrated an equal training response to both modalities.
