concentric function
|
|
aggregate muscle group
|
all muscles that do elbow flexion
|
|
view activity
|
determine which muscles are preforming the movement, what type of contraction,what kind of exercise are appropriate to develop the muscles--look of weak link
|
|
break down all movements into
|
phases
|
|
number of phases varies depending on skill
|
3-5
|
|
prepatory phase
|
movement phase follow through phase
|
|
may also begin with
|
stance phase

|
and end with
|
recovery stage
|
|
major phases may be
|
subdivided
|
|

|
|
action
|
part of skill
|
|
usually near maximal concentric contraction of
|
