Résumé

This study was designed to calculate the critical velocity (v crit ) and anaerobic distance capacity (ADC) of prepubescent children for running events. Thirty-four prepubertal children underwent a graded field test to exhaustion in order to determine peak oxygen uptake (peak [Formula: see text]) and maximal aerobic velocity (MAV). Then, in random order, they performed five runs to exhaustion (tlim) at relative velocities corresponding to 90, 95, 100, 105, and 110% of MAV. The linear relationships between distance limit (dlim) and tlim were calculated in order to determine v crit (slope of the relationship) and ADC (intercept). Very high individual coefficients of determination were found between dlim and tlim (0.98 < r 2 < 0.99; p < 0.001). The v crit was significantly correlated with peak [Formula: see text] (r = 0.73; p < 0.001). However, no relationship was found between ADC and the maximal accumulated oxygen deficit. In conclusion, our results indicated that, for children, the relationship between dlim and tlim could be calculated with tlim ranging from 2 to 10 min, and that v crit is a good indicator of the aerobic fitness of children. Nevertheless, further studies will have to be conducted to validate the use of ADC as an indicator of children's anaerobic capacity. Key words: aerobic power, anaerobic capacity, comparison, model, performance
