3D Motion Capture Systems for Golf
An Overview for Golf Professionals
What is 3D motion capture technology?
3D motion capture technology is used to record and analyze the movement of humans or objects using sensors and/or cameras. It is used in film and animation, robotics, and virtual reality to record and recreate realistic movement. 3D motion capture is also used in biomedical research and education to study the movement patterns of certain diseases and teach biomechanics. Lastly, 3D motion capture is utilized in sports science to study and optimize sports-related movement patterns.
What 3D motion capture systems do golf instructors use?
3D motion capture systems are popular with golf instructors to analyze movement patterns in the swing and show video analyses to their athletes. Some systems can also be used to monitor motion in real time and give feedback to correct athlete movement.
There are several different options on the golf market that range in price from $1,500-$100,000. Some current options are:
K-Motion: K-Vest is a wearable sensor system that tracks data at four points on the body during the golf swing and shares it to a mobile device.
Swing Catalyst - Swing Catalyst uses force plates and cameras to track motion and records data points that include pressure shift, weight distribution, and ground reaction forces in the swing.
Trackman - While Trackman is a launch monitor, it uses ball data to estimate swing plane, club path, club speed, loft, launch angle, and more.
Gears - Gears is the most technically robust system. It uses 8 high-speed cameras and 32 sensors placed around the club and body to measure numerous data points.
ETRAK - ETRAK provides 3D motion data from 1-2 sensors at a time and provides accurate, real-time data on range of motion, velocity, or acceleration at any point on the body or club. Two sensors can be used to analyze motion ratios (ex: hand speed versus torso speed). The ETRAK system can also find point of impact to use in comparing data points. Lastly, ETRAK can be used in training sessions to provide auditory feedback to ensure quality reps.
Why should I use 3D motion capture as a golf instructor?
Motion capture systems provide objective data points on your athletes so you can monitor the effectiveness of your program and show its value to clients. When athletes are able see movement and understand the impact that even small changes have on their game, buy-in and training adherence increases. Finally, systems that provide training feedback can improve communication with your athletes and help you get better results faster..
How do I choose a 3D motion capture system?
When picking a 3D motion capture tool for your golf academy or team, make a list of:
what data you want to collect
your budget
where you will use it - in one place or multiple locations and inside or outside
Also, be honest with your knowledge of biomechanics and choose a system that provides educational materials to support your understanding and continuing education. 3D motion analysis is complicated but can be mastered with time to make you an even better instructor.
Using this list, research the tools above to see what best fits your knowledge level and goals. Interested in getting a free ETRAK demo? Send us a message at info@etrak.tech today!
