The combination of forces produced by different parts of the human body. When a person is moving or attempting to move an object, several different parts of the body act together to maximize the force. In theory, force summation occurs when all body parts act simultaneously In practice, the strongest and lowest body parts around the center of gravity (e.g. trunk and thighs) move first, followed by the weaker, lighter, and faster extremities. This is known as sequential acceleration and results in successive force summation. To obtain a maximum force, summation also needs sequential stabilization of body parts, with some body parts having to be fixed at stable points while other parts produce the effective forces.
If your practicing an event in your mind and not actually doing it that's called mental rehearsal.
