Abstract des Autors
Background and aims: The aim of this study was to check the constant presence of the slow component of VO2 (cl) in 12 prepubertal children (mean age: 10.7 years; 146.1 cm; 43.1 kg). Methods: All subjects performed an incremental ramping test to identify the loads at the first ventilatory threshold (Sv1) and at VO2max; 2 tests were then carried out on different days, using constant loads before and after aerobic training with loads calculated as percentages of the difference between VO2max and SV1 in a wide range. cl was clearly evident in all subjects. Results: The training programme used in 5 children alone significantly reduced the VO2/W cost by reducing the breadth of cl. Conclusions: The authors propose a method for the measurement of the O2 saved based on a calculation of the area between the 2 cost curves VO2/W before and after training; this method allows a more accurate evaluation to be made of this relationship.
