So to start this week I got off to a great start with a really good workout tonight. I hit it extra hard tonight to try and make up for some of my time off. I felt really good, but did get a little tight in the hamstrings and quads. Obviously the time off does have its effects. My only regrets of lately have been my diet. I have gotten away from making my food and eating healthier and have fallen back on quick and easy food. Partly because of work/school stress and time constraints and partly because I got bored of eating the same foods. I will try and do some meal planning tuesday night and some food shopping wednesday evening so that I can get back on track. I am toying with the idea of another 24 day challenge!!
I believe two weeks ago I mentioned there was some big things in the works. Well there was! On Wednesday February 29th my coach and I drove down to Penn State to visit Mike Duffey and Eric Handley and do some one of a kind data collection. I was fortunate enough to be the test subject for a first of its kind data collection of a golf swing utelizing three 3D systems, AMM/TPI 3D, Qualisys and Zenolink. For those of you not familiar with these systems you can find more information about all three systems at their respective websites, AMM/TPI, Qualisys and ZenoLink. I will give you the cliffs notes, AMM is an electromagnet system, you use a pick up to define the space and have electromagnet sensors placed on your body and wires that connect them to a computer. Qualisys is a video motion capture system that uses reflective orbs on a spandex/velcro suit and ZenoLink is done by using two video cameras, one face on and one at an angle of 30 degrees from down the line. You film a calibration cube and then film your swings. You would then upload the information to ZenoLink and then will perform a direct linear transformation and process your data.
This would be the first captures of its kind ever done. Getting a single swing on all three systems at one time to compare the information between all three mediums is pretty spectacular to say the least. The whole experience was pretty awesome. Mike and Eric has their research center all set up for our arrival and even recruited the help of some interns, One PGM senior named Matt, and two Kinesiology students named Julie and Eric. Here are a couple pictures of the facility.
To caputre the swings with all three systems I first had to be wired up to the AMM/TPI 3D system. After i was all wired up and calibrated, we then put on the spandex/velcro suit and then Julie, Eric and Matt placed all the markers on me and we calibrated me and my golf clubs (driver, 5 iron, 8 iron and pitching wedge) to the space via the Qualisys system. I forgot to mention we had calibrated the space by placing the ZenoLink calibration cube on the mat where Matt is standing in the above picture. We recorded 10 swings with each iron and 15 swings with the driver.
I dont have any pictures of me all suited up, I had forgotten to grab my camera and give it to Dan before we got started, but I think Eric might have taken a picture or two and hopefully I can get my hands on a copy to put up here as well. It was really quite the sight.
I am very fortunate to take part in some pretty cool stuff. I would like to take a brief moment to thank Mike Duffey, Eric Handley and the Penn State students Matt, Eric and Julie for their hospitality and for a really good time. I would also like to thank my coach Dan Parks for allowing me the opportunity to take part in some cool research. Look for a write up in a future issue of JAGR.
As always thanks for reading. Stay tuned there are more things in the works!
