Fig. 2. Data from 141 trials of 18 individual Terrapene ornata walking on the level showing (A) rate of oxygen consumption versus speed for all trials, (B) cost of transport (COT) versus speed for all trials, and (C) minimum COT (COTmin) for up to 10 trials for each individual versus speed. Dashed line indicates the expected COT based on mass (Full, 1989). Average resting VO2 (±1 s.d.) is shown as a filled circle at 0 m s–1.
