The ideal forces to train movement adaptation are movement forces. Learn how to use acceleration, deceleration, change of direction, and coordination activities/drills for an holistic approach to training. For example the external active forces involved in sprinting can reach five times bodyweight and some internal forces associated with this activity are ten times bodyweight and occur in less than 200 milliseconds. It makes sense to pay attention to the way we are producing forces (acceleration) and reducing forces (deceleration) from a central perspective. This knowledge can complement the other forms of training that you are currently using.
