Experiments show that the more muscle elasticity is used, the less energy is consumed. Because the reaction force generated by muscle elasticity can make it easier for you to reach the required position and save energy for your body to move to this position. Taking animals as an example, the elasticity of mouse tendons is worse than that of horses, so mice consume much more energy when walking than horses (assuming the same weight). If you run the same distance, the oxygen consumption of mice is about 16 times that of horses. Similarly, people consume 2-3 times as much energy when walking fast as when running the same distance at the same speed. If you pay attention, you will find that horses often like to trot for a while after running at a medium speed to rest their muscles. Race walkers will also jog for a period of time after the race, using muscle elasticity to relieve fatigue and reduce consumption. All animals, including people, have the instinct to adapt their feet to energy consumption. It is for this reason that walking slowly to visit the exhibition is much more tiring than running the same distance slowly on the road.
This study shows that walking consumes much more energy than people think. Then, at the same speed and distance, running is actually not as good as walking.
