Document Summary

Skeletal growth: some examples of similar constraints, individual constraints: two arms, two legs, upright posture, environment: gravity, can be seen across variety of motor skills, often produce more force, velocity, or accuracy. Force generation aided by planar movements: use force in the plane of motion where you want to move yourself or an object, avoid rotational movements that reduce force in the desired plane. Increase rotational velocity (swing it faster): larger radius of rotation = larger linear velocity. Increase relative length (fully extend it at release or contact): linear velocity = rotational velocity*radius of rotation. Increase base of support widen stance, point toes outward: lower center of gravity bend the knees. Final comments: the principles of motion and stability apply to all actions and obects, be aware of changing individual constraints, manipulate task and environment to aid in optimal skill performance, not everyone will become proficient.
