The Motion Analysis Corp. golf swing analysis application creates measurements of the critical biomechanical parameters during a full left or right handed golf swing. It supplies a complete kinematic and kinetic report of the legs as well as measurements about the player's technique. The information can be used compare the biomechanics among players, or show comparisons of the same player over time. This guide will step through the procedures to properly acquire the golf swing trials and then operate GolfTrak.

Data Collection Setup
Data collection for GolfTrak is similar as with any collection. There are some settings for calibration and data collection that you should use that will help ease the process. Learn about the recommended data collection settings in Data Collection Setup.
You should already be familiar with how to collect 3D data using Cortex. However, JumpTrak requires some specific collection procedures to ensure correct calculations. Trial Collection describes the recommended workflow to collect your trials.
Running the GolfTrak Application
Now that the trials are collected, data are clean and events selected, you can use the GolfTrak Application to perform the calculations and generate the reports. Click to watch the Video Tutorial on how to use the GolfTrak Application:
To run GolfTrak, Click Applications>GolfTrak
Complete the Subject Information fields for the golfer: Now Select the Trials that you want to process with GolfTrak, and click on the Generate Reports button. The Kinematics and Kinetics graphs will be populated for the last selected trial. Check that the graphs are filled and do not have errors. If you want, you can print out these reports by right clicking in the presentation graphs pane and selecting File>Print Graph Image. Open the MS Excel program and select the trial that you want to view. The Excel workbook will have three tabs. A listing of the data will be on the first tab, with the Graphs and WebReport on the other tabs. Here is an example report in Excel:
A green check box and a red check box will indicate within or outside normative ranges.
