Video analyse voor elke sport

SwingerPro is the ideal software tool for the analysis of motion in sports. It is primarily used in golf, tennis and cricket. A digital video camera and a laptop computer are also needed.

SwingerPro has all the functions and features that will allow you to make good use of video while training or teaching a golfswing, especially the full swing. In the full swing, the golfer can't know what he exactly did or does. The mirror on the driving range is rather useless. Your eyes are supposed to be on the ball only. To know what you do (wrong) you should be able to see what your coach sees. There are many ways to work with Swinger. But a striking example is depicted by the following situation: hitting balls on the driving range. The video camera is on a tripod and feeding the video frames to the laptop computer. The laptop is showing in real time what the camera sees. An acoustic trigger controls all recordings while you are training on your own or taking a lesson with the golf pro.

Here above you see Wouter de Vries training in that way. With every ball he hits, the laptop records and stores the full swing on the harddisk of the computer, about 2 seconds at a time, as triggered by the sound of the ball being struck, that is 1 second before the ball was hit to show the backswing and downswing and 1 second after the hit to include the forward swing and finishing position. After making the swing he walks over to the laptop and sees that last swing play back automatically even without touching the computer. He judges his swing and goes on for the next swing. The computer stored that swing and is ready to record the next swing. This way, using 'enhanced capture mode', he works on his golfswing only and needs not bother with the operation of camera or computer.

And the golf coaches does not waste his time by looking at the video's after the lessons, while playing tapes back and forth. But the golf coach can do something extra: put the swings on CD! You take all the video clips, add some comment, put them on a CD and let the pupil have them and to look at it in his own time. To repeat the lesson. The golf pro may even include some examples to look at or drills to work on. A lesson to remember. That's added value for you.

In conclusion, the golf pro will not lose valuable time while benefiting from the advantages of digital video, but will be able to generate extra business. Not only by distributing and selling CD's with the captured golf swings of his students, but also using the same CD's to market and promote his method, his golf school, clinics and pro shop items. And finally, the same CD is a very good way to include information of your sponsors. Sport-in-Beweging can help you produce these items.

In comparison to previous ways of using video in sports, Swinger has the following striking benifits:

Technical (with Digital Video and PC) sharper images with shutter speeds such as 1/3000 or better interlaced images in 25 fps are transformed to 50 fps no need for video tape, video clips are stored in the computer direct access to video clips as stored full control for play-back, slow motion, etc. text can be added to any frame video clips can be edited, stitched together, compressed video clips put on CD to play-back on any PC

Organizational (new ways for teaching) video clips during the lesson, not in extra time quicker analysis of faults visual feedback, not words understanding of the dynamics, not statics matching with examples (LAW's of the golf swing) swings on CD can include drills or marketing material swings can be emailed for distance coaching added value and new business

A nice example of one of the functions in SwingerPlus can be seen from the following image. Joanne Foreman, a former Tour professional demonstrates her swing. Using the 'strobe' function, it is immediately clear how much power she generates. The path of the swing demonstrates proper weight-shift and well maintained wrist hinging.

Additional measurements showed good rotation with 45 percent torque, only 3 degrees left bend; about 30 degrees right bend. Just marvelous. From "the Science of the Swing" by Michael Mc Teigue: "Proper hip and shoulder rotation is critical to generating power. But it's not simply how far the hips and shoulders rotate; rather it's the difference between the two rotations on the backswing (torque) and the ability to close this gap on the downswing."
