Behaviour, temperature and terrain slope impact estimates of energy expenditure using oxygen and dynamic body acceleration

Table 1 Top model set explaining energy expenditure associated with; (a) standing at different temperatures, (b) walking at different speeds on the level and (c) walking at different speeds for each slope, with all simpler nested models within ΔAIC_c = 6 retained for inference

Sl = terrain slope. The degrees of freedom (df), amount of variation explained (R²), AICc’s and Akaike model weights are shown for each model.
