It’s Racquet Science, not Rocket Science!
A number of unique scientifically-devised tests* were carried out under controlled and dynamic conditions in the test lab and on the tennis court to check the efficiency and performance of the Own the Zone band vibration dampener on tennis racquet vibration. These special tests were performed by Dr. Nissim Benjuya Ph.D. Senior Lecturer, BioMedical Engineering and Physical Therapy, Ben Gurion University, Be’er Sheva, Israel.
Dr. Benjuya, age 53, an author and co-author of 53 scientific articles in the field of bio-mechanics, recently passed away. Dr Benjuya was also the Director of Motion Analysis at Children’s Hospital Sheba Medical Center, Ramat Gan, Israel and Director of the BioMechanics Lab at Kaye College of Education, Be’er Sheva, Israel. May his memory always be a blessing to those who knew him and to everyone he helped during his lifetime.
Specifications
All balls impact the racquet in the central region of the strings
- “Control” has no dampener on strings
- “Volts of Excitation” refers to an electrical signal caused by the movement or vibration of the strings and racquet immediately after ball impact
- Graph 3 recorded at ball speed of 40 – 50 miles/hr
- The sampling frequency was 10 Khz for one second of recording
- Graphs capture 300 – 500 millisecond (ms) time frame
- See Bar Graphs 4 and 5 for testing of Zone and other vibration dampeners
Test 1: Zone vs Control (no dampener on strings)
