Introduction: Agility defined -- Biomotor requirements for agility -- The Parisi approach to agility training -- Preconditions: Introduction -- Base of support -- Center of gravity -- Muscle force vectors -- Parisi formula: A=acceleration -- D=deceleration -- S=stopping -- R=reacceleration -- C=conditioning -- I=Injury prevention -- Parisi agility rule -- Progression. Stationary exercises: Broad jump / land / acceleration -- Side jump / land / acceleration -- Broad jump / land / run -- Side run / land / stop / reaccelerate side run -- Movement exercises: 5 yard side shuffle -- 5 yard forward and backward -- Sample workout
