Document Summary
Pronghorn: really fast organisms consume a lot and have a very high metabolic rate. Running speed for tetrapods: relationship between speed and metabolic rate is a linear relationship, big mammals consume less energy running at the same speed. The larger individuals need less energy to go a faster speed. Optimal costs of transport for a horse. Predicts what speed an organism uses the least amount of energy to engage in a certain gait to move a certain distance. Minimum cost of energy expenditure at a certain speed. Optimal cost of transport for a bird flying. Running may be more cost efficient than walking depending on the speed: biomechanical differences. Feet leave the ground when you run. Big tendons store energy that is captured in gravitational potential energy. Legs act as springs when you run: various locomotion. Minimum cost of transport in relation to body size is used to determine efficiency. Flippers (coddle fins) help fish move in the water.
