CoPF VPOWER, SPEED & ACCELERATION(sub components) powered by instructors alliance Jonathan Blake BSc (hons) BSc (physio)
Definitions • Acceleration • change in velocity over time (highest possible rate of velocity increase)
Speed the complex ability to perform fast motor actions in the shortest possible time
Power • (the time rate of doing work) • strength incorrectly associated with force production at low velocities and power is force production at high velocities – • (explosive strength) • the rate at which physical work is performed ability to exert maximum muscular actions (instantly) in explosive bursts of movement
The Speed|Strength Continuum • (pre)determined by the external resistance that must be overcome • starting strength • acceleration strength • absolute strength
Plyometrics • the ‘shock’ method (Verkhoshansky ‘77) • harnesses the Stretch Shortening Cycle (SSC) to increase power output
