Just for fun I have posted a video clip off my desktop showing the graphics used to illustrate some of the new 3-D motion capture software out there. This is a side view, frt view, and an ariel view along with a chart showing in degrees the rotation of the pelvis, upper body, and the separation (x-factor) btw pelvis and upper body vs. time. This is actually a division 1 Sophmore pitcher.
Some of the bennefits of this type of software is that you get any angle without a single camera (the sensors are magnetic). Data is sampled at 240 times per second vs. 30 times per second with standard camera. This type of software will actually give any quantity desired. i.e. rotational segment velocities, linear postition, accelerations, Rotations angles and a graphical interphase to analyze what you see.
I wanted to get some feedback on this persons mechanics based on the video. But I also wanted to know what you all think about the usefulness of the software. Keep in mind I couldn’t show much data (If there is any particular measurement or quantitiy you would like to see please let me know). The animation only has a picture of the body parts that I choose to mark in this protocol. That’s why the legs are missing, except the feet. I can actually measure where the knee is located based on original position and segmental measurements taken before the software was used. Any feedback or ideas would be helpful.
This is the first video i’ve posted so if it doesn’t work I’ll try again
