Understanding Motion

Moe Norman’s swing is a biomechanical masterpiece. Every part of his body moves like a finely tuned machine. Yes, Moe was a ball-striking machine. If I had to describe his swing in just a few words it would be – powerfully efficient.

Having an efficient golf swing describes how each part of his swing moves the right amount at the right time in perfect sequence and time. When this happens the club produces speed, the goal of all efficient golf swings.

In the graph below, you can see the colored lines showing how each part of the body moves in relations to each other part.

There are some significant details to recognize here. You can see them if you just look at a few of the lines together. Looking at the Red and Green line (Pelvis and Torso) you can see how related they are when it comes to producing speed.

Notice that as the swing moves into the backswing where the Green line is lower than the red line. This is the middle of the backswing where the torso moves faster than the pelvis. As the pelvis slows into the backswing (red line) it then begins to move forward and beats the torso into impact. This is called Separation where the pelvis separates and moves independently from the torso.

As the torso (green line) moves from the top of the backswing into the downswing it is speeding up and you will notice that the torso and pelvis slow down at the same rate into impact.

The next graph might be the most revealing. where you can see the torso movement (green line) as it relates to hand movement/speed (brown line). You can see that as the torso slows into impact, the hands accelerate into that final moment.

My favorite chart is to look at the fastest moving part of the body vs. the slowest moving part of the body – the Hands (brown line) vs. the Pelvis (red line).

Here you can see the wide ranges of the speed of the hands vs. the speed of the pelvis. While the Pelvis (Red) is slowing, the hands are moving the fastest – a clear indication that as the pelvis slows down (decelerates) the torso is able to rotate and accelerate the arms and hands.
