説明

Ventilation threshold (VET), threshold of decompensated metabolic acidosis (TDMA) and lactate threshold (LT1, LT2) were investigated during incremental bicycle exercise for 20 boys (11.7±0.1 years) and 10 girls (11.2±0.2 years) .<BR>Maximum oxygen uptake (VO2max) was measured by treadmill running. There was significant difference between boys and girls in VO2max per body weight, but no signif-icant difference per LBM. Mean values of each threshold (% peak VO2) were as follows. VET was 53.3±2.2%, TDMA was 69.0±2.2%, LT1was 51.8±2.2% and LT2was 72.8±2.2%. These values were not higher than those of previous adult's data. There was no significant difference in lactate and ventilatory parameters between boys and girls, except LT2and LT4mM.<BR>In conclusion, it seems that no difference is seen in lactate and ventilatory responses between 9-12 year boys and girls. VET and TDMA by bicycle exercise could be estimated by ventilatory responses in prepubertal children.
