“Anyone who hopes to reduce putting or in any other department of golf to an exact is in for serious disappointment and will only suffer from the attempt…”
“It is wholly a matter of touch, the ability to gauge a slope accurately and most importantly of all, the ability to concentrate on the problem in hand, that of getting the ball into the hole…nothing more!”
- Bobby Jones

What is Biomechanics?
Biomechanics is the science of human movement: Sports biomechanics uses the scientific methods of mechanics to study the effects of various forces on the sports performer. It is concerned, in particular, with the forces that act on the human neuromusculoskeletal system, velocities, accelerations, torque, momentum, and inertia. It also considers aspects of the behavior of sports implements, footwear and surfaces where these affect athletic performance or injury prevention. Sports biomechanics can be divided up into two sections: Performance Improvement & Injury Prevention

“Putting is an art!! But you must have the five basic keystones of putting”
Dr. Paul Hurrion

Quintic Ball Roll
• Automatically track roll and spin characteristics of the golf ball first 12”
• Speed of putt
• Backspin / forward rotation (degrees)
• Side spin – hook or cut (rpm)
• Distance to true roll
• Vertical bounce / Launch angle

You must understand what the ball is doing…

The Five Keystones of Putting

1: Posture & Set-up

2. The blade of the putter needs to be square at address and at the strike position. If somebody addresses the ball with the blade open and / or closed and they say ‘But I always hit it online…’ but when the pressure’s on, it doesn’t work, they are vulnerable

3. The blade of the putter needs to be square to the path of the stroke through the hitting area. In other words, you don’t want to put a slice or hook spin on the ball, because if you do, on its first contact with the ground, the ball will endeavour to spin just like an off-break or a leg break in cricket… It may only be a minute amount of spin, but it will be sufficient to cause the ball to track off the intended line of putt.

4. It is crucially important that the ball is struck with a slight upstroke, so that when you strike it you create forward roll on the ball. That can be achieved but have the ball in the perfect position and having the right plane of strike as you hit the ball. There’s no magic secret to it… roll the golf ball!

5. Every putt is a straight putt, but it depends on how hard you hit it, whether or not it takes any break that you may read into the green. To achieve the desired result one needs an ideal, smooth acceleration, not deceleration, through the ball.

Rapid Acceleration (short backswing)

• Speed at impact 1.75 msֿ¹
• Max speed 2.11 msֿ¹
• 0.06 seconds AFTER impact
• Poor distance control

Deceleration of putter through impact (long backswing – short follow through)

• Poor distance control
• End up quitting on the stroke
• Speed at impact 1.63 msֿ¹
• Max speed msֿ¹
• 0.08 seconds BEFORE impact!

It is very difficult to control the putter head (open or closed) with a blade that is slowing down…

Constant speed at impact: No acceleration (Backswing 48% & Follow through 52%)

• Constant speed = Good rhythm
• Speed at impact 1.84 msֿ¹
• Max speed 1.86 msֿ¹
• 0.025 Seconds AFTER impact
• Constant speed at IMPACT = great distance control

“Most three putts aren’t cause by bad green reading, but by bad judgement of speed”
Ben D. Crenshaw

Fit the putter to the golfer!
The 3 L's: Length, Lie, & Loft

• Find the correct weight of the putter head and shaft,
specific to the individual.
• Eye alignment and perception of square
• Measuring the ball's performance is key
