It has been called club release, wrist uncocking or club lag. What is really being discussed and how does it affect your swing? Club release or wrist uncocking refers to the angle made between the club shaft and the plane of the arms as they move around the axis of the trunk.
In the downswing the golfer's arms drive down to the ball. Using energy created by the lower body and passed through the core region to the upper body, the arms achieve increased rotational speed.
As the arms accelerate, the angle between the arms and the club shaft remains the same, in a cocked position. When the arms begin to decelerate, however, energy passes from the arms to the club, causing it to increase in rotational speed.
The visual result is a change in the angle between club shaft and the arms, hence the phrase club release or wrist uncocking. If timed properly, the club accelerates to maximum velocity upon impact with the ball, resulting in optimum power production.
Club release is easily seen by the unaided eye as the increase in angle between the club shaft and the arms when the swing nears impact with the ball. Until now, however, we have not had the technology to measure and analyze this action objectively, causing the evolution of many erroneous explanations of the visual perception.
Two common misconceptions are the benefits of holding the club in a cocked position until impact, or forcing the release by throwing the club from the top.
Holding the cocked position interferes with the action of the arms accelerating around the axis of the trunk and reduces club head speed. In reality, the action of the arms accelerating around the axis of the trunk is what creates the cocked angle and maintains that angle during the downswing.
When the arms begin to decelerate, the club angle should increase into impact as the club accelerates. Tension in the muscles of the wrists and arms caused by trying to hold the cocked angle typically results in the disruption of the natural energy flow.
This disruption creates a premature deceleration of the arms and consequently a premature release of the club angle, as well as increased stress in the upper body and arms. Be sure to avoid this mistake.
The other common misconception is throwing the club from the top. Again, the club achieves greatest acceleration when the arms decelerate and the cocked position automatically releases.
Trying to force the release most often disrupts energy flow and creates tension in muscles, causing a premature deceleration of the arms and less impact power.
Effective golf swings create and release the club angle with productive arm action. Productive arm action results from the following combination of sequential movements:
|Power generation using the large muscles of the lower body.|
|Efficient transfer of energy from the legs through the core muscles to the upper body and shoulders.|
|Acceleration of the arms for optimum energy culmination and maximum power production.|
