Hopping run
The hopping run is a bipedal gait. Mainly children between kindergarten and elementary school age show this moving picture, which is different from walking , running and symmetrical hopping . The child jumps alternately with the right or left foot, while the other leg is pulled up at an angle as a swing leg . Then it first lands on this foot again and with a slight delay with the other foot, in this intermediate step the talus is changed. In contrast to walking, the hopping run has a phase without ground contact, longer even than when running, and in contrast to running, a phase where both feet touch the ground.
For adults, the hopscotch run is a slower or less efficient locomotion than running, but for lighter children and people in low-gravity environments, the metabolic profile shifts . The astronauts Ed Mitchell and Gene Cernan of the Apollo missions preferred an intermediate form of hopping and hopping out of several possibilities of two-legged locomotion on the moon's surface. Hopping runs can also be found in some birds , lemurs and jerboa .
