Essay Instructions: Analyse the muscles involved in the backhand action of the tennis shot. this should include all of the muscles that initiate and assist in this motion. Include a table of the origins and insertions of each muscles involved. The muscles of the legs that play a distinct part in the action should also be included.
The first part of the investigation should be to define the action, and what each of the body parts is doing at each point in time.

Essay Instructions: Essay to be based on: A right-handed male is playing a game of tennis.

Analyse the muscles involved in a ONE handed backhand tennis shot. please include all the of the muscles that initiate and assist in this motion. Include a table of the origins and insertions of each of the muscles involved. Break the moves into the 1) the push off 2) trunk 3) swing also describe what is happening at each phase, for each joint that is involved. You will need to use the following terminology: flexion, extension, abduction, adduction, medial/ lateral rotation, ect when describing the movements. Break the moves moves into phases. Those muscles of the legs that play a distinct part in the action should also be included.
The first area of investigation should be to define the action, and what each of the body parts is doing at each point in time.
