WHAT YOU DON’T KNOW, DOES HURT YOUR GAME! As a rising tennis champion, your dreams are your life. You work hard. You know your strengths. You know your weaknesses. You have searched for help from highly reputable professional instructors. However, chances are, without 3D motion analysis, you and your coach do not know the real cause of your weak spots. Even the greatest pros and coaches cannot see or detect problems with certainty without the help of 3D motion analysis.
Tennis motion happens fast. Too fast for human eyes to accurately quantify and analyze. 3D Motion analysis gives you and your coach the information you need to maximize your technical performance by displaying visually and quantitatively where you can improve and capitalize on your talent.
Based on research in the area of Dynamic Visual Acuity, (the visual discrimination of an object when there is relative movement between the object and the observer), in a high speed collision sport, such as tennis, certain high speed events simply cannot be observed with human eyes.
Eastman Kodak Company reported that events occurring in less than 1/4 of a second usually cannot be seen by human eyes. Even video replay misses critical action because it takes only 30 pictures per second in 2D. Replays are chunked and choppy and regularly miss critical moments of the swing. 3D motion analysis will reveal essential details about your swing that cannot be seen or measured by advanced slow motion video software.
With 3D Motion analysis it is possible to detect and analyze essential elements to strengthen and perfect your swing. For example, did you know that, accelerating knee extension on your serve by a few hundredths of seconds too early will cause your center of gravity to raise too soon and fall too early when serving? The habit of accelerating two hundredths of a second too early causes constant falling at impact. This falling decreases serving performance by impeding the upward velocity of your racket head at impact and significantly increases your chance for injury in the wrist elbow and shoulder joints of the hitting arm.
No human coach can see these two events standing on a tennis court. Dynamic Visual Acuity deteriorates rapidly when the eyes move at an angular velocity of greater than 60-70 degrees per second. As the coach moves his eyes from the knees to impact on a 5′ 10″ player who meets the ball at 100″, the angular velocity of his eyes is typically 80 deg/sec. (This is assuming the coach can be in a controlled environment, with an unobscured view, leaning against the back fence, giving him/her the best chance to specifically observe the knee extension with the naked eye.)
And what about video? Can this be done with robust sports slow motion editors or analyzers? No. It cannot. Non-3D systems have many calibration and focal challenges that make calculations tedious and most often inaccurate. They might calibrate a value of knee flexion, but it will be inaccurate over multiple frames. Knee joints change positions due to hip joint rotations, and additionally, velocity and accelerations are not measured.
