Walking, running and sprinting
Walking, running and sprinting are the actions of moving the body forward. Similar muscles are used in all these actions. But the mechanics and the level of muscle contraction and aerobic respiration are different. Muscles are mainly used for support and forward propulsion. They work harder during running and sprinting and some muscles and tendons function differently, soleus and the Achilles tendon for example.
Running and sprinting differs from walking in several ways: the time spent in the stance phase, whether the knees are flexed of locked in extension and the level of involvement of the Achilles tendon in recovering energy from ground contact for propulsion. Aerobic respiration in running is greater than in walking.
Running is over longer distances for endurance and sprinting is over shorter distances and for speed. Running includes jogging, road racing, cross country running, fell running, trail running and marathons. Other forms of running include running and jumping over hurdles and running and weaving such as in rugby and some types of football. Weaving will increase contraction and tighten the lateral muscles of the body, for example ….
