How much body weight does running impose compared to walking?

When considering the forces acting on the body during running compared to walking, research indicates that running can impose forces that are approximately five and a half times a person's body weight. This significant increase in impact is due to the dynamics of running, where the body experiences greater gravitational forces during the push-off phase and landing, resulting in a more substantial load on the joints, muscles, and bones.

This heightened level of impact can lead to increased stress on the body compared to walking, which typically only imposes forces around one to one and a half times body weight. Understanding this distinction can help in recognizing the implications for training, injury prevention, and the physical demands placed on the body by different forms of locomotion.
