Alexander Slayton…

is a graduate of Lafayette College where he studied Mechanical Engineering with Dr. Steven Nesbit. Alex joined the Jacobs 3D team in 2017.

Jacobs 3D is the first ever golf teacher analysis program to derive the forces that a golfer applies to the club during the golf swing. It is expanding our understanding of exactly what, how, and when the most important elements of the swing happen. Instead of “waiting” to see kinematic results, Jacobs 3D is giving us a look at what is happening earlier in the chain of events. Having access to this information will transform how everyone studies the golf swing—and provide a much clearer, quicker path for player improvement.

In 2017, Nesbit and Jacobs added a Full Body Bio Mechanical analysis to the existing club program. We now have access to the internal forces within a golfer and we can figure out faster than ever how golf swings differ from each other.

Over the past 30 years, Mechanical Engineering Professor Dr. Steven Nesbit has conducted the most influential research in the history of our sport. As a researcher for the USGA, he conducted research on equipment, the actions that the golfer applies to the club during a swing and a full bio mechanics study on the human body. His research has shaped the rules of the game and the understanding of how the golfer moves the club and body in a swing. After his work with the USGA, he went on to study other sports like baseball and tennis.

Other than a few “student interest” research papers, his work was dormant beyond published papers and unpublished studies at the USGA. In 2010, Jacobs met Dr. Nesbit and they discussed and studied his prior research and he was very intrigued to see a dedicated golf pro applying the findings and conclusions of his research papers. Steve’s interest in golf was reinvigorated in 2014 and they decided to launch a new layer of research together with the commission of the Jacobs 3D golf swing analysis software.

Jacobs 3D, evaluates both the kinematics and kinetics of the golfer. You can break a golf swing down into those two categories, but the kinetics category had never been attempted before by a golf teacher.

KINEMATICS DESCRIBE THE MOVEMENT

KINETICS ARE THE FORCES THAT CREATE THE MOVEMENT  

Traditional software packages are great at measuring kinematics (movement), but they don’t show the kinetics, or forces at play. For example, we could already see kinematically the motion of the club twisting on the downswing as the player squared the face. We could see that it twisted, and how fast it was twisting, but we wanted to know how much force/torque it took the player to twist it, and when in the swing that twisting effort started to happen. The ability to do that wasn’t out there, so Jacobs decided to solve the problem . He built his own software —Jacobs 3D.
