Document Summary
What is speed and agility: speed, the ability to reach a high velocity of movement. Clear mechanical definition (distance/time): agility (sheppard & young, 2006, the ability of an athlete to accelerate/decelerate and change direction rapidly, the ability of an athlete to accelerate/decelerate and change direction rapidly in response to a stimuli. Is usain bolt agile: different sports have different movement profiles, speed and agility are related traits, but are often seen to only share small amounts of common variance (little & williams, 2005, anthropometry, morphological, technique/neural control, biochemical. Limb length: directly impacts on biomechanical outcomes, changes height of com from the ground, somatotype clear sporting bias towards certain body shapes. Involves maximising motor unit recruitment ft motor units: firi(cid:374)g rate a(cid:374)d speed of ap"s, regulation of excitatory and inhibitory reflex feedback. Intermuscular coordination: the ability of the agonist, antagonist and synergist muscles to contribute fully to the target activity. Involves minimising antagonist co-activation and maximising synergist contribution.
