Swing Analysis at TWU Biomechanics & Motor Behavior Laboratory


WelcomeGolfer

Biomechanics Laboratory at Texas Woman¡¯s University currently provides swing analysis services primarily to elite golfers such as professional players and competitive amateurs (junior/college players and low-handicap [5 or lower] players). The swing analysis is designed to detect subtle issues and is mainly for elite and low-handicap skilled golfers.

Swing analysis at TWU is based on our research findings and provides an in-depth analysis of your swing. This swing analysis service is a part of our golf biomechanics research program. A 10-camera optical motion capture system operating at 1,000 Hz and two 3-dimensional force plates are used for swing capture, and Kwon3D Motion Analysis Suite is used for data analysis and report generation.

We also provide re-programming sessions without formal swing analysis to non-competitive amateur golfers (5 handicap or higher) on a limited scale. If you'd like to schedule a reprogramming session, please go to the Reprogramming Service at TWU Biomechanics Lab page.

How to Schedule a Swing Analysis Session

To schedule a swing analysis session, you will need to send the following info and 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 are ready, click here to request a swing analysis session. While filling out the request form, you will be directed to the scheduling calendar. Please sign up for an available time slot and enter the date in the request form. Requests with no scheduled session date will be deleted automatically.

Note that, after the initial assessment of your swing clips, your session may be converted to a reprogramming session. We normally do the swing analyses on Fridays and Saturdays only. You may request a session on a specific date but it may not be honored as it depends on the availability of the Lab and the students.

Motion Capture Attire

To minimize the marker movements on the skin/clothes (marker motion artifacts), we require the following motion capture attire:

  • Men must wear spandex shorts. You will be asked to take off your shirt. If you do not have your own shorts, you may use ours.
  • Ladies must wear spandex shorts and either sports bra (preferred) or sleeveless spandex shirt. Please bring your own spandex.

We enforce these clothing requirements to assure accurate motion capture and analysis.

IMPORTANT: Refrain from wearing lotion on the body as it affects the adhesiveness of the double-sided tape used to fix markers on the body. Markers may fall off during the swing capture due to the lotion applied.

Since force plates are covered with artificial turfs that provide sufficient traction, you may wear your golf shoes or sneakers. In case of sneakers, avoid those with reflective emblems/tapes as shiny tapes can cause issues in the marker labeling process.

Clubs

Bring your clubs. Our standard swing analysis includes three club conditions: driver, iron (5-iron for men and 6-iron for ladies), and wedge (pitching wedge). Additional clubs may be added depending on your specific needs. It may be a good idea to bring the whole bag.

Time Requrements

This is typically a three-hour session:

  • 1st hour: swing capture and processing. A typical motion capture session (7 trials per club condition * three club conditions) will take approximately 45 min. including marker placement and trial capture. A total of 65 retro-reflective markers will be placed on your body, club, and the ball mat. In addition, data processing (marker labeling) will take about 20 min.
  • 2nd hour: feedback. Allow 1 hour for going over the analyzed data.
  • 3rd hour: re-programming of the swing pattern. Based on the data and diagnosis, the overall movement pattern will be re-programmed. Intuitive and instinctive swing drills such as the step drills will be used in re-programming your swing pattern.

Since TWU-Denton is located about 30 min from DFW (Dallas-Fort Worth) International Airport or 40 min from DAL (Dallas Love Field), you may arrive in Dallas in the morning and leave on the same day in the late afternoon.

Analysis Areas

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 mid-hand point and upper body joints
  • Ground reaction force and moment
  • Torques generated through the foot-ground interaction (GRF torque and pivoting torque)
  • Center of mass motion
  • Linear and angular motions of the pelvis
  • Kinematic sequence
  • Mid-hand force and torque

A report and select stick figure animations will be provided after all trials are fully processed.

Some useful drills will be suggested during the feedback session so it is ideal to come with your coach. Junior golfers must be accompanied by a parent or a coach.

Donation

The Biomechanics & Motor Behavior Lab is a research component of the School of Health Promotion and Kinesiology, operating through grants and donations. Please support continued research activities through a ($500 suggested) donation for a golf swing analysis.

Directions to TWU-Denton and Location of the Lab

mapTWU-Denton is located in Denton, Texas, about 30 min. north of Dallas, Texas. Please do not be confused with our Dallas campus (TWU-Dallas). The closest commuter airports are DFW (Dallas-Fort Worth) and DAL (Dallas Love Field). It takes about 30-40 min from these airport to the campus.

On weekdays, use "304 Administration Dr, Denton, TX 76204" as the destination in your navigation app. This will lead you to Administration Dr on the campus. Please park at the Main Visitor Parking Lot on Administration Dr (Location 1 in the map). Visitors can pay for parking in this lot through ParkMobile, a pay-by-cell parking app. For this, you will need to download the ParkMobile app from Google/Apple Store and create an account prior to your arrival. Or you can use your existing ParkMobile account.

During the weekend (Sat-Sun), Use "1607 N Bell Ave, Denton, TX 76209" for your navigator app. You can park anywhere on the compus near Pioneer Hall except the 24/7 reserved parking lots. No need to pay the parking fee in the weekend.

Biomechanics & MB Laboratory (Location 2 in the map) is located in Pioneer Hall (Room 123), the red-brick gym building on N. Bell Ave. Swing analyses/reprogramming sessions will take place in Room 124, Motion Analysis Laboratory (Location 3 in the map). Come directly to the Motion Analysis Laboratory (Location 3).

For your information, TWU campuses are "smoke-free." Per Texas Woman¡¯s University¡¯s Tobacco Policy the use of tobacco products is prohibited indoors and outdoors on the Denton, Dallas and Houston campuses. This includes all facilities, student housing units and the off-site TWU Select Apartments. E-cigarettes are permitted outside TWU buildings. Visitors must comply with the university¡¯s Tobacco Policy.
