The purpose of the present study was to clarify the physiological characteristics of grass skiing from the viewpoint of aerobic and anaerobic metabolism. In slalom (SL), O_2 requirement was 3.488l and the energy sources were derived 11.7% from aerobic, 69.8% from alactic and 18.5% from lactic metabolism. On the other hand, in giant slalom (GSL), O_2 requirement was 4.086l and the energy sources were derived 31.7% from aerobic, 52.8% from alactic and 15.5% from lactic metabolism. In 20s maximal bicycle ergometer pedaling, O_2 requirement was 4.443l and the energy sources were derived 8.8% from aerobic, 55.7% from alactic and 35.5% from lactic metabolism. On the other hand, in 50s pedaling O_2 requirement was 5.848l and the energy were derived 29.4% from aerobic, 38.2% from alactic and 32.4% from lactic metabolism. O_2 requirement in SL and GSL was corresponded to about 70% and 80% of O_2 requirement in each bicycle ergometer pedaling. And they were represented by low blood lactate concentration. From these results it was concluded that in grass skiing the energy supply derived from lactic metabolism would be little and the contribution rate of alactic metabolism would be high.
