Document Summary
Skeletal muscle is striated, while cardiac muscle is not (allows for forming joints) Intrafusal muscle: monitor how much the extrafusal fibres have stretched (length: gives a proprioceptive sense, allows for knowledge of body position. Motor learning: a set of internal processes associated with practice or experience, leading to a relatively permanent gain in performance capability. Motor control: an area of study dealing with the understanding of the neural, physical, and behavioural aspects of movement. Performance benefit: get better at performing the skill, but it does not mean that the skill has been completely learned! (learning benefit) The historical development of motor learning/control is composed of four areas. In the 1960s, it became a real field of study: psychology: Arthur melton: pilots can be selected based on specific individual abilities. A battery of tests given to recruits. Turns out he was wrong-simple tasks don"t show how one will perform on complex ones.
that measures the performance of someone learning a skill as a function of the training time t. At ļ¬rst, the rate of learning is rapid. Then, as performance increases and approaches a maximal value M, the rate of learning decreases. It has been found that the function
where 
and 
are positive constants and 
is a reasonable model for learning.
