Recently Medbo et al., (1988) investigated maximal anaerobic capacity using the method of maximal accumulated oxygen deficit in adults. Our study examined accumulated oxygen deficit as an anaerobic capacity of children. Ten healthy male children (10.6+/-0.24 years) with a mean peak oxygen uptake of 53.87+/-2.5 ml/kg/min volunteered as subjects for the study. The children performed a series of steady state workloads in order to construct the linear regression for predicting supramaximal workloads for estimates of 110, 130 and 150% of VO2max. The three supramaximal constant load tests were performed to exhaustion in random order using Douglas Bags for expired air collection. The accumulated oxygen deficits at workloads predicted for 110, 130 and 150% VO2max were 1.27, 1.32 and 1.29 litres, respectively. There was no significant difference for the accumulated oxygen deficits at the three supramaximal workloads. The results demonstrate that the maximal anaerobic capacity of children may be obtained via the method of accumulated oxygen deficit. The results support similar trends, but quantitatively less values than those obtained in adult populations. Verf.-Referat
