Fig. 2From: Behaviour, temperature and terrain slope impact estimates of energy expenditure using oxygen and dynamic body accelerationa Predicted relationship between \({\dot{\text{V}}\text{O}}_{2}\) (ml min−1) and DBA (g) while pygmy goats were walking on a treadmill at three different slopes; level (0°), negative slope (–15°), and positive slope (+ 15°). The shaded area shows the 95% confidence interval. b The correlation between DBA (g) and walking speed (km s−1), while goats are walking on a treadmill at different speeds and different slopesBack to article page
