High Elbow Catch

[katypfarmgirl]

I am confused...once the hand is extended, leaving the patient lead hand, then there is a theory (if i understand this) the hand and elbow drop below the elbow which stays in place/high so there is a 90 degree angle at the elbow. And then the push to the hip.

So in TI the "anchor is where the hand floats comfortably down to in the water which seems much deeper under the surface than conventional swimmers. Does that precluded getting a " high elbow catch".

Mike Phelps video really exemplifies the high elbow catch.

How important is this for the TI technique??
