Dave Scott talks about four common faults:
head position
overreaching
overextension
dropped elbow

the videographer analyzes Ian Thorpe's stroke, and while I disagree with much of his analysis it is great slow motion video of Thorpe.
BUT, Thorpe enters his right arm fully extended with the elbow and forearm actually entering the water just before the hand does, see attached video frames. This is exactly what Dave Scott describes as overextension.
I am wondering whether it actually makes any difference how you enter the arm if you are fully extending the arm before starting the catch?
back to your original question on over extension (assuming head is in correct position).......i have been trying to slightly increase my arm extension out in front and it seems to help with a more forceful body rotation and a higher angle of rotation (ship vs barge). also seem to be able to get into a rhythm better......:dunno:
