The Physics of Human Flight

Running is not just moving fast; it is a series of controlled jumps. Unlike walking, where one foot is always on the ground, runners spend moments completely airborne during every stride.

To the laws of physics, running acts like a bouncing spring rather than a pendulum. Your tendons and muscles store energy like a coiled spring when your foot hits the ground, then release it to propel you upward. This unique mechanics allows us to minimize energy waste during high-speed travel. It is fascinating that your own body functions as a sophisticated trampoline every time you decide to pick up the pace.
