Just wondering. How many of y'all are using the front quadrant swimming technique? I have been using the book and DVD-Total Immersion and trying to adjust my stroke. When I do the stroke correctly it is so much easier-effortless. I feel like I am able to reduce the drag I create when swimming the way I was taught to swim years ago. I'm interested in anyone's experience with FQS. Thanks:)
I recently picked up a copy of the TI book and have found it most interesting. I was particularly interested in the concept of how the hips seem to provide the power in the arm stroke. The examples used were of golfers and baseball players and how by rotating their hips, they can hit the ball a "mile". I then looked back at the Counsilman book, the New Science of Swimming, for a discussion of hip rotation and found the following:
"It has been suggested that body roll can be used to enhance force output in the arm pull. This line of reasoning goes so fas as to suggest that hip rotation is the "power source" of arm movement in the crawl stroke. This idea has been extrapolated from the use of hip rotation in swinging a baseball bat or golf club. Aside from the unique biomechanics of these activities, the use of hip rotation as the primary means of generating movement in the baseball and golf swing is possible because the lower extremities are in contact with the ground. Such activities constitute what is known as a closed kinematic chain. Swimming is considered to be an open kinematic chain because water is not a solid enough medium against which feet can plant themselves. This makes it unlikely that hip rotation can contribute to the generation of significant force in the arm pull of the crawl stroke. It is even less likely to occur in the strokes in which no body roll occurs, such as breaststroke and butterfly."
Given that rebuttal, can anyone explain the TI concept of hip rotation and force output in the arm pull?
