Table 2. Angle displacements of the chest joint during giant slalom (GS) gate running and reference free-skiing.

Mean (Standard deviation)				12.4 (6.3)			8.9 (7.1)

The reference data are angle displacements in free-skiing (middle turn with a slalom ski) and were measured on the same slope among three sit-skiers. The overall trend was similar in both runs, and the mean of the differences was approximately 10%.
