Components of the Swing:
In the beginning, the ball is placed (NOT pushed) into an arc by means of control, and if held at waist level of lower, with some force. It is controlled (NOT pushed) in order to accommodate the initial relationship and movements of the feet and ball. When the ball in the stance is held at waist level or below, force is used in order to effect an arc in the ball placement. Once placed, the ball moves down into the backswing by means of gravitational acceleration. At the bottom of the backswing, kinetic energy (stored energy) is employed until the ball reaches the height of the backswing.
After a momentary pause at the height of the backswing, the ball moves into the downswing, once again under the influence of gravitational acceleration. In the delivery, the ball reaches a point where its gravitational force begins to compromise with kinetic energy (at the point of release). At this time, acceleration (force) is applied, and the release and follow-through ensue (fastest part of the swing).
Some other important points to remember:
From shot to shot, the length of the swing must be consistent.
Place a towel under your bowling arm and don’t drop it until your follow-through begins. This is an excellent training method since only by keeping the arm against the body can one succeed in keeping the towel in position.
Keep your elbow behind the ball throughout the swing (inside part of the elbow faces the body), which in turn will place your bowling hand under and behind the ball, effectively ensuring leverage at the release point.
Basically, there are three areas to consider when addressing the swing: 1- its nature in terms of length, speed and type of energy used 2- its direction 3- the relationship of its movements (in the delivery as well as the approach) to other parts of the body, especially the feet.
Problems usually arise during the approach sequence, beginning with stance, pushaway direction and timing with the footsteps, direction of the bowling shoulder and bowling arm during the pushway, speed of the pushaway as related to the length and speed of the steps, etc.
Work on one thing at a time, and if you can’t figure out what to correct or even where to start, seek the advice of a “Qualified†coach, and not just someone who sees you as a walking dollar-sign.
Good luck
