Bioengine,

In my lessons, I often use video. Most people learn well visually, especially when the subject is themselves!

As you have implied, video is a limited presentation of (1) alignments (geometry); (2) stroke component variations, action and sequencing (physics); and (3) any recommended improvement (objective and subjective analysis).

I am intrigued by your work, and without bias or an attitude of confrontation, ask the following questions:

1. At what point -- 100-shooter, 80-shooter, 70-shooter or TOUR pro -- do your quantitative 'physical' measurements (segment speeds, acceleration/deceleration, muscle groups and their 'firing', etc.) add value to the more limited video procedure?

2. Assuming the data indicate inefficiencies and the potential for improvement, how do the procedures you recommend differ from that of more conventional instruction?

3. Finally, how do you help your student translate that quantified data/information into its athletic equivalent, i.e., a more efficient golf stroke?

Yoda,
Biomechanic companies also use video to capture data, They place the sensors on the person and then use video to capture data. Although they capture data at full speed. To capture human motion you only need 11 hertz. A stock standard camera has a capacity of 30 hertz.When you lose data is when you slow the video down or break into frames. We don't lose data cause we don't slow the data down.

An example was the other day we tested a guy on video when we slowed down his swing it appeared the guy was engaging his lower body first. The coach and I swore he did. When we process the data and we look at his 3D data he was starting his downswing arms first. This was due to this transition was between frames.

We test and provide evaluations for many sports. In golf, Tennis and baseball, testing thousands athletes in all three sports they all had something in common. The kinetic link. They all create speed from the ground up. All three sports had similar movement patterns.

There is a natural way the body wants to natural move to create speed from the ground up. This is from conservation of momentum (starting from the ground up) and muscular loading, The muscular loading is what drives conservation of momentum.

In the golf swing we look at movement patterns and how a golfer creates speed or power. Also identify if there is a power leakage and can tell you why.

An example a golfer always hit the ball fat, what causes this. Arm deceleration to early in the downswing. What is causing arm deceleration to early in the downswing. A power leakage some where. We pin point when this occurring and why. This could be even to do with ground forces. Or muscular loading a ton of reasons. By measuring hip accel/decel,upper body accel/decel,arms accel/decel and club accel/decel, the kinetic link and muscular loading, with tell us what the human body is doing and if this is effecting your geometry. There's tons of other stuff we measure as well like ground forces, lower body stability and club dynamics.

Any level of golfer should get tested, even a beginner should get test to work out if you have a geometry problem of physics problem. Movement pattern issue.

We use our 3D data to develop a training program, which is designed for each individual, the exercises and training programs are designed to train the body to create better movement patterns or kinetic link. They are also designed to train the body how to load and fire muscle in each body segment in the right timing and sequence. You can't train your body to achieve this on the practice fairway. We are training movement patterns not geometry.

Ever exercise, drill and training program has been tested to see if they improve a certain movement patterns and body speeds. There not made up on belief systems, every thing we do is tested.

We teach people how to create better movement patterns not geometry, once we get someones movement patterns right they go back to their coach to apply geometry.
