I saw this picture in my recently received USA Diving magazine.  What an amazing pike position!  This is interesting biomechanically, for two reasons; 1) Moment of Inertia – I recently discussed how to make a somersault spin rapidly and here is the picture perfect example.  I don’t think a pike could be any tighter and for him, his moment of inertia is as small as he is … [Read more...]

Susie Corona and I use the AmmTrainer3D software with one AmmSensor between her shoulder blades to demonstrate how we can effectively train the top of back swing posture.  The software is set to give a positive tone when she is in the correct posture for all three angles; forward bend, side bend and turn.  This method allows the golfer to quickly recognize where they should be … [Read more...]

Gord stated that 3D quantifies the motion of the golf swing objectively; this is true, but one might immediately think “But wait, I can measure distance and angles on a 2D video screen by drawing lines.” Yes, you can … [Read more...]

Here is an article written by Gord Workum; a Titleist Performance Institute Instructor on why 3D Motion Capture (and Analysis) is better than simple 2D video analysis with regard to the golf swing.  I like it and I will follow up with another article adding my point of view. The only way to measure the efficiency of a golf swing is with 3D Motion Capture; with 2D one can just … [Read more...]
