She points out that the one thing every great Olympic freestyle has in common is pulling with high elbows, and mastering this, not reducing drag, is how swimmers get faster in the water. Cheers, Kevin I don't think the debate would last very long because the purpose of a high elbow catch IS to reduce drag. It's not because it is a powerful catch. When considering the drag forces that result from different ways of pulling with the arm underwater, one must really concentrate on what is happening with the upper arm, more than the lower arm. It turns out that when one decides to pull deep with the pull, the upper arm gets off axis immediately and the drag coefficient of the swimmer skyrockets. Pulling with the early vertical forearm position keeps the upper arm more in the line of motion of the swimmer at the beginning of the pull. When the swimmer is finally forced to sweep the upper arm to the side for the recovery, the upper arm remains in the unfavorable drag position for a shorter period of time. Remember, tenths of seconds in unfavorable drag positions are enough to nearly stop us in the water. Gary Hall Sr
