Abstract
Maximal aerobic power tests on a treadmill and on a bicycle ergometer while sitting upright and in a low-sitting position were performed by 7 males and 5 females. Treadmill .ovrhdot.VO2 max [maximal O2 uptake] for men and women combined was 4.0 and 11.2% higher compared to upright and low-sitting cycling, respectively. Maximal pulmonary ventilation, related respiratory measures, and heart rate were similar in all 3 tests. Submaximal work performed in the 2 cycling positions resulted in similar levels of O2 uptake, ventilation and heart rate. Work loads of 360 and 720 Kpm[kilopound meter]/min were performed by males with O2 uptakes of 14.7 and 25.2 ml/kg .cntdot. min, which corresponded to 30 and 52% of their upright-sitting maximal O2 uptakes and to 33 and 55% of their low-sitting aerobic capacities, respectively. O2 uptakes for work loads of 360 and 540 Kpm/min by females were 15.6 and 21.6 ml/kg .cntdot. min, being equivalent to 42 and 58% of the maximal O2 uptake in the upright-sitting, and to 43 and 60% in the low-sitting ergometer position, respectively.
