Abstract des Autors
Physiological and perceptual responses at ventilatory threshold (VT) and VO2 peak were examined in 10 male children (10.2+/-1.3 yrs) during graded treadmill and cycle exercise. Treadmill VO2peak (57.9+/-6.7 ml/kg/min) was higher than the cycle (51.7+/-7.7 ml/kg/min). Ventilation and heart rate (HR) were higher on the treadmill, while respiratory exchange ratio (RER), rating of perceived exertion (RPE), capillary blood lactate, and test duration were similar between tests. The VO2 at VT was higher on the treadmill (36.7+/-4.6 ml/kg/min) than the cycle (32.5+/-4.4 ml/kg/min). When VT was expressed as a percentage of VO2 peak, there was no difference between tests. The RPE at VT, HR at VT, and VT expressed as a percentage of HRpeak were also similar between tests. Similar to VO2 peak, the VO2 at VT is dependent on the mode of exercise. However, when VT is expressed as a percentage of VO2 peak, it is independent of testing modality. The RPE at VT appears to be linked to a percentage of VO2peak rather than an absolute VO2.
