Fig. 2From: Can metrics of acceleration provide accurate estimates of energy costs of locomotion on uneven terrain? Using domestic sheep (Ovis aries) as an exampleEffect of treadmill angle and speed on animal pitch, VeDBA and rate of oxygen consumption. A Animal pitch, the angle of the spine, (°) against the slope angle of the treadmill (°); B vectorial dynamic body acceleration (VeDBA, g) against treadmill speed (km h−1); C rate of oxygen consumption (log (V̇O2, mL kg−1 min−1)) against the slope angle of the treadmill (°). The black line denotes the predicted linear effects model and the red line denotes the predicted quadratic effects model; D rate of oxygen consumption (log (V̇O2, mL kg−1 min−1)) against speed (km h−1) of the treadmillBack to article page
