The competitive running is a part of Athletics. Many body parts are used in the activity of running. The lower body is directly used in running. Upper body is used indirectly and for support and balance. The major limbs used while running are the legs. Applying force through the leg muscles prompts the runner to move forward. More vigorous the leg movements, the faster the runner will run. Running activity is very similar to walking. But the difference is the speed. Another difference is that while running, both the feet of the runner are off the ground quite regularly, whereas, in walking, at least one foot will be on the ground all the time. Running is also more vigorous than walking.

The upper limbs of a runner assist in maintaining balance and works as a support system. The movement of the arms while running helps in maintaining body balance. This action helps in maintaining the center of gravity at the proper place. Apart from the arms, the other limbs that are used in running include torso and shoulders. It is also possible to run without the help of the arms. But it will definitely be inconvenient. The application of proper running techniques is essential for a professional runner. This will help in remaining injury free. Serious injuries can cut short a professional running career. The use of wrong running techniques has all the reasons to injure a runner.
