How do humans run?
Running uses a lot of different muscles as your legs move you forwards, for example, your quadriceps (thigh muscle) extends your leg forwards and keeps your knee stable, and your calf muscle lifts your leg off the ground. Running is physically different than walking. When you walk you always have one foot on the ground, but when you run you are pushing your body off the floor so both feet are off the ground. Sweating to cool off and your body using water and nutrient stores to keep your body going can leave you dehydrated and in need of nourishment. You need to replenish these supplies by drinking plenty of water and eating a healthy snack after a run.
Why do humans run?
Runners around the world have many reasons to run. For some, it simply might be to manage weight, while others it might be for competitive reasons. Exercise is an effective treatment for mental illness such as depression. Exercising releases endorphins, which are natural chemicals in your body, that make you feel calm and positive.
How should someone get faster in running?
Running takes practice. If you want to run faster, try increasing your speed by about 10 seconds every time. This helps increase your stamina and eventually helps you run faster.
