Golfer Services at TWU Biomechanics & Motor Behavior Laboratory
The Biomechanics & Motor Behavior Laboratory at Texas Woman¡¯s University offers two types of services for golfers: swing analysis and reprogramming. Please select the service that best suits your needs and qualifications.
Swing analysis: This service is designed for elite golfers, including professional players, college players, teaching professionals, and low-handicap junior players and amateurs (5 handicap and lower). Note that after an initial assessment of your swing clips, your request may be changed to a reprogramming session if significant swing issues are identified.
Reprogramming: This option is for less-skilled golfers or those who prefer not to undergo a swing analysis.
Swing analyses are typically conducted on Fridays and Saturdays, while reprogramming sessions are held only on Thursdays and Sundays. You may request a session on a specific date outside the regular schedule in special circumstances; however, such requests are subject to the availability of the Lab and its staff. Please contact us in advance at kwon3dxp@gmail.com.
Sessions are currently available on the calendar through July 2025. Please check available time slots:
Swing Analysis Calendar | Reprogramming Calendar
Go to Swing Analysis or Reprogramming to schedule a session. Please begin the scheduling process only when your current swing clips are ready.
***ON-SITE GROUP REPROGRAMMING SERVICE: If you have a group of 4-5 golfers interested in reprogramming at your golf club, please contact Dr. Kwon at kwon3dxp@gmail.com for available dates and conditions. Sessions are typically held on Saturdays.
Swing Analysis
The swing analysis service is tailored for elite golfers and is designed to detect subtle issues that cannot typically be discerned through simple observation. Based on our research findings, the swing analysis at TWU offers an in-depth evaluation of your swing.
This service is part of our golf biomechanics research program. We use a 10-camera optical motion capture system operating at 500 Hz, along with two 3-dimensional force plates, to capture swing data. The Kwon3D Motion Analysis Suite is then employed for data analysis and report generation.
Time Requirements
This process typically takes three hours:
- First 1.5 hours: Warm-up, preparation, marker placement, and swing capture. A typical motion capture session (7 trials per club condition across three club conditions) takes approximately 45 minutes. A total of 65 retro-reflective markers will be placed on your body, club, and ball mat.
- Data processing: Marker labeling and report generation take about 30 minutes.
- Final hour: Feedback and review of the analyzed data.
For long-lasting effects, it¡¯s ideal to bring your coach. Junior golfers 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 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 requires the use of retro-reflective markers. A total of 65 reflective markers will be placed on both your body and club. To minimize movement of the markers on the skin or clothing (marker motion artifacts), specific motion capture attire is necessary.
- Men: Please wear spandex shorts and be prepared to remove your shirt. If you do not have spandex shorts, we can provide them.
- Women: Please wear spandex shorts and either a sports bra (preferred) or a sleeveless spandex shirt. Bringing your own spandex attire is requested.
These clothing requirements ensure accurate motion capture and analysis.
IMPORTANT: Avoid applying lotion to your body, as it reduces the adhesiveness of the double-sided tape used to secure markers. Lotion may cause markers to fall off during swing capture.
Since the force plates are covered with artificial turf that provides sufficient traction, you may wear golf shoes or sneakers. If wearing sneakers, please avoid those with reflective emblems or tapes, as they can interfere with the marker labeling process.
Clubs
Please bring your clubs. Our standard swing analysis includes three club types: the driver, an iron (5-iron for men and 6-iron for women), and a wedge (pitching wedge). Additional clubs may be included based on your specific needs, so it's recommended to bring your entire bag.

Reprogramming
Our reprogramming service is designed primarily for less-skilled golfers seeking to improve their swing mechanics. A reprogramming session differs significantly from a typical golf lesson, as its main focus is on retraining your movement patterns. Our goal is to teach proper body movement throughout the swing. In a typical reprogramming session, we employ a series of effective practice drills, including two-step drills, along with simple but powerful tools to enhance the golfer's gross movement patterns.
To benefit fully from a reprogramming session, golfers should have a reasonable level of fitness and body control, as the session will involve a substantial number of swings. It¡¯s important to note that while reprogramming aims to correct inefficient movement patterns, it may not be effective in overcoming limitations caused by physical conditions or health issues. Additionally, it may not be suitable for beginners who haven¡¯t yet established a consistent swing pattern. 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 video may be posted on this YouTube channel.
A typical reprogramming session lasts about 2 hours. We begin by recording your "before" swing, then work through various drills tailored to your needs and responses.
Attire & Clubs
Wear comfortable athletic clothing and shoes that allow for a full range of motion; avoid clothing that is too loose. As the session includes numerous swings, a glove is recommended, and you may want to bring a towel if you tend to sweat. Golf shoes are not necessary.
For the session, please bring your driver and an iron. Although the driver will be our primary focus, you may use an iron for warm-up. We¡¯ll allocate about 10 minutes for warm-up and stretching.

How to Schedule a Session
To schedule a swing analysis or reprogramming session, please have the following information ready along with your swing clips:
- Name
- Age
- Gender
- Status (junior/college/professional) or handicap (low-handicap amateurs)
- Brief sketch of your golfing career
- Physical characteristics such as injury/surgery history
- Residence city/state
- Swing clips (face on & down the line)
If you HAVE YOUR CURRENT SWING CLIPS READY, and would like to schedule a session,
Step 1. Open the Swing Analysis Calendar or Reprogramming Calendar, depending on your needs. Check available time slots and sign up for an open spot. 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, 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.
Step 2. Submit the Swing Analysis Request Form or Reprograming Request Form. You will be asked to attach your current swing clips (required). Enter the scheduled appointment date on the request form.
Requests without a scheduled appointment or appointments without an accompanying request form will be automatically deleted within three business days.
Blockout Dates
No golfer service is available during the following periods:
- Mid Dec - mid Jan
- Mid Mar
- Late May
- Mid July - mid Aug

YouTube Videos
The reprogramming session will be fully recorded. Typically, the entire session video, along with a short highlight video, will be posted on YouTube (@DrKwonGolf) as public videos after minor editing. However, if you prefer, you may request that the session video be posted as a private video, so it is not shared publicly on the channel.
The feedback video from a swing analysis will always be posted on the aforementioned YouTube channel as a private video.
