FIS points correlated against gross efficiency (GE) and work rate accounted efficiency for 31 male and 19 female elite cross-country skiers while roller ski skating on a 5 and 12% inclined treadmill in the G3 and G2 skating technique respectively.

Incline	Group	GE	E-WR
5%	Men	r = −0.65*	r = −0.55*
	Women	r = −0.75*	r = −0.63*
	All pooled	r = −0.64*	r = −0.53*
12%	Men	r = −0.75*	r = −0.72*
	Women	r = −0.81*	r = −0.72*
	All pooled	r = −0.65*	r = −0.69*

E-WR, the measured metabolic rate was subtracted from the estimated value for metabolic rate at each individual's measured work rate (using linear interpolation of the work rate–metabolic rate relationship).
