In children as well as for adults, risk factors for cardiovascular health includes physical fitness. Peak oxygen uptake (.VO2peak) is a commonly used method of assessing aerobic fitness. Higher .VO2peak values (5-10 %) have been found on treadmill for adults, in a number of studies. Scarce evidence exists for children, and we investigated how the test modus influenced the .VO2peak results in boys. Twenty boys aged 9.1±0.3 yr (mean ± SD) were tested on the treadmill and on a cycle ergometer. Mean .VO2peak was 1.71±0.21 vs 1.63±0.17 L min-1 for running and cycling, a difference of 4.7 % in the favour of running. Maximal heart rate (HRmax) was 203 vs 195 beats min-1 (3.9 %). Breathing frequency (BFmax) was 66.7 vs 61.2 breath min-1 (9.1 %), respectively. Tidal volume (VT) was 4.6% higher when cycling. Both test forms achieved the same degree of criteria fulfilment for a maximal test. Children can use both test forms, but results will be better on the treadmill. This must be taken into account when comparing different studies of children that have used running or cycling as work form.
