Golfer Services at TWU Biomechanics & Motor Behavior Laboratory
The Biomechanics & Motor Behavior Laboratory at Texas Woman¡¯s University currently provides two types of golfer services: swing analysis and reprogramming. Select the service suitable for your needs and qualifications.
Swing analysis is tailored for elite golfers such as professional players, college players, teaching professionals, and low-handicap junior players and amateurs (5 handicap and lower). Please note that after an initial assessment of your swing clips, your request may be converted to a reprogramming session if the swing issues are evident.
Reprogramming is designed for less-skilled golfers or those who do not wish to undergo a swing analysis.
We typically conduct swing analyses on Fridays and Saturdays, and reprogramming sessions on Thursdays and Sundays only. While you may request a session on a specific date outside the regular schedule due to special circumstances, it may not be honored as it depends on the availability of the Lab and students. Please contact us in advance at kwon3dxp@gmail.com.
Sessions are currently available on the calendars up until July 2024. Check available time slots:

Swing Analysis
The swing analysis service is tailored for elite golfers and is designed to detect subtle issues that cannot normally be discerned through simple observations. The swing analysis at TWU is based on our research findings and offers an in-depth analysis of your swing.
This swing analysis service is part of our golf biomechanics research program. We utilize a 10-camera optical motion capture system operating at 500 Hz, along with two 3-dimensional force plates, for swing capture. The Kwon3D Motion Analysis Suite is then employed for data analysis and report generation.
Time Requirements
This is typically a three-hour process:
The 1st hour is for swing capture and processing. A typical motion capture session (7 trials per club condition * three club conditions) will take approximately 45 minutes, including marker placement and trial capture. A total of 65 retro-reflective markers will be placed on your body, club, and the ball mat. Additionally, data processing (marker labeling) will take about 20 minutes.
The 2nd hour is for feedback. Allow 1 hour to go over the analyzed data.
The 3rd hour is for mini reprogramming of the swing pattern. Based on the data and diagnosis, adjustments will be made to the gross movement pattern with a focus on specific areas.
For long-lasting effects, it is ideal to come with your coach. A junior golfer must be accompanied by a parent or coach.
Analysis Areas
A typical swing analysis covers the following areas:
- Detailed stick figure representation of the swing
- Postures at various swing events
- Functional swing plane analysis
- Motion planes of the hand center
- Ground reaction forces and moments
- Torques generated through the foot-ground interaction (GRF torque and pivoting torque)
- Center of mass motion
- Linear and angular motions of the pelvis
- Kinematic sequences
The feedback session will be recorded, and the video will be available for review.
Motion Capture Attire
Optical motion capture necessitates the use of retro-reflective markers. A total of 65 reflective markers will be placed on both the body and club. To minimize marker movements on the skin or clothing (marker motion artifacts), specific motion capture attire is required.
Men are required to wear spandex shorts. You will be asked to remove your shirt. If you do not have your own shorts, you may use ours.
Women must wear spandex shorts and either a sports bra (preferred) or a sleeveless spandex shirt. Please bring your own spandex. These clothing requirements are enforced to ensure accurate motion capture and analysis.
IMPORTANT: Please refrain from applying lotion to your body, as it affects the adhesiveness of the double-sided tape used to secure markers. Markers may fall off during the swing capture if lotion is applied.
Since the force plates are covered with artificial turf that provides sufficient traction, you may wear your golf shoes or sneakers. If wearing sneakers, please avoid those with reflective emblems or tapes, as shiny tapes can cause issues during the marker labeling process.
Clubs
Please bring your clubs. Our standard swing analysis includes three club conditions: the driver, an iron (5-iron for men and 6-iron for ladies), and a wedge (pitching wedge). Additional clubs may be added depending on your specific needs, so it's advisable to bring your whole bag.

Reprogramming
The reprogramming service primarily caters to less-skilled golfers. A reprogramming session differs significantly from a typical golf lesson, as its main focus is on reprogramming your movement pattern. Essentially, we aim to teach proper body movement during the swing. During a typical reprogramming session, we utilize a series of useful practice drills, including the two-step drills, along with simple yet effective tools to enhance the golfer's gross movement pattern.
To benefit from a reprogramming session, the golfer must have an adequate level of fitness and body control, as a considerable number of swings will be taken during the session. It's important to note that while the reprogramming session aims to improve poor movement patterns, it may not be effective in overcoming limitations imposed by physical conditions or health issues. Additionally, it may not be suitable for novice golfers who have not yet established a consistent swing pattern. Furthermore, a reprogramming session is not intended to replace regular lessons, and we encourage participants to attend with their coach, if possible.
Examples of typical reprogramming sessions can be found on YouTube: @DrKwonGolf. The entire reprogramming session will be recorded, and with your permission, the recorded video will be posted on the aforementioned YouTube channel.
Typically, this process takes about 2 hours. We begin by recording your 'before' swing and then use various swing drills tailored to your needs and responses.
Attire & Clubs
Wear comfortable athletic clothes and shoes that won't hinder your full-effort swings. Avoid clothes that are too loose. A glove will be required as numerous swings will be taken. Please bring a towel if you tend to sweat a lot. Golf shoes are not necessary.
For the reprogramming session, bring your driver and an iron. Although we'll primarily use the driver, you may use an iron for warm-up. We'll allocate 10 minutes for warm-up and stretching.
