Document Summary
Change is motor behaviour over the lifespan through maturation, and impacts of learning on movement. Organ development, cranial development, circulatory system ~5 weeks. 40% blood flow to the brain and upper body. Movement transition to games and athletic skills. Sexual maturation, through anabolic hormones and increase in muscle mass for males, and advanced motor performance. Peak performance, however dependant on opportunity and frequency of skilled performance. Physical activity and nutritional interventions can slow age related decay in motor function. Increased attentional focus, cognitive function, mu recruitment, reaction time and fluid intelligence. Learning of skilled movements through practice and experience. Response programming: organise and initiate the action. Can be measured via the reaction time. Reaction time can be slowed by making cues so the task is more difficult. Number of different plays forming the same formation. Complicate movement so the opponent must process information more before responding. Increase difficult of the skill so more difficult task must occur for successful outcome.
