Maximum Clubhead Speed is achieved almost instantly
at Release for
both Swingers and Hitters (2-M-1 and 6-F-0). The Clubhead does
not
pick up Speed during the Release Interval (the Overtaking of the Hands by the
Club). Instead, it tends to slow down!
Swingers use the Body Pivot as a
Rotor to accelerate the
Left
Arm. This generates Momentum Transfer (from the Rotating Body into the
extending Radius of the Left Arm and Club per 2-K) and the Throw-Out Action
of Centrifugal Force. This combination virtually eliminates Clubhead
Deceleration during Release, and as a result, the Clubhead maintains a
constant speed into Impact.
Hitters, on the other hand, use the Body as a
Launching Pad
from which to Drive the
Right Arm. Hence, Momentum Transfer is
unavailable to prevent Release Deceleration. Therefore, the Timing and
Trigger Delay of the Right Arm Thrust become critical in preventing a massive
slowdown of the Clubhead during Release. Learning to handle this Release
Deceleration problem is one of the biggest stumbling blocks the Swinger must
overcome when learning to Hit.
For both Swingers
and Hitters, Impact is a violent collision of Ball
and Club. Since the Ball hits the Club as hard as the Club hits the Ball, the
Clubhead decelerates significantly. The Ball's mass is about one-fifth (20
percent) of that of the Clubhead, and so the Clubhead's Approach Speed is slowed
to approximately 80 percent at Separation. It is important that this Impact
Deceleration be minimized because in addition to its own 70 percent
Coefficient of Restitution, the Ball picks up 100 percent of the Clubhead's
Speed at Separation. In this department, the only defense is the familiar
mantra of
The Golfing Machine...
Sustain the Lag!
