Take a Big Enough Backswing so your Subconscious has a Smooth Choice



By the time you have at least 6 full years of lawn bowling experience, your subconscious can be given responsibility for controlling the weight in your lawn bowling delivery. As David Bryant suggests in a useful video tutorial: you choose an aim line to bowl down; you take a stare point on that line; and then you look back and forth between this stare point and the target position (usually the jack) until you feel comfortable with the visualized trajectory. Then you let your mind go blank and send the bowl over your stare point.


Now, even though I have been bowling for 13 years, I have been playing rubbish bowls for the first few weeks since coming to Valverde LBC in Almancil Portugal, where I am spending the winter months.


What was going wrong? Usually, the most common error I make is failing to get my stepping foot planted before my arm swing delivers my bowl.

No— that wasn’t the problem. Maybe I wasn’t careful and methodical enough drawing my bowling arm back along the extension of the aim line behind the mat. No— checking that didn’t solve things.


Analyzing my bowl results suggested that the problem was related mostly to weight. For too many shots I found myself pushing out the bowl and applying too much energy at the end.


Well, I have now found the answer. Often, my backswing wasn’t high enough to smoothly propel my bowl the required distance and my subconscious was trying to compensate for this by over-accelerating my swing somewhat, trying to ‘steer’ the bowl and destroying smoothness from the motion.


In contrast, my subconscious had no difficulty slowing my arm motion down when bowling to a short jack even though my higher backswing would have permitted me to easily deliver to jacks at any length.


P.S. When you have less than 6 years of experience playing lawn bowls I have found you need to consciously control those elements of your swing that affect length (backswing length, crouch degree, step length, etc.) because your subconscious does not have a big enough ‘training set’ to do it itself.

Interpreting What You Can See from the Mat




Above you can view a head of bowls with a long jack as seen from the mat (top) and then taken from just in front of the head (below). Using the rules in the table below you can quickly work out the disposition of the bowls without visiting the head. 

In order to bowl the proper length, you must be able to provide accurate information to your subconscious computer.  You need to tell it whether your last bowl was long or short and by how much. Particularly in singles, this must be done at least part of the time by an estimation done from the mat. You can't go back and forth to the head after every bowl! Even in non-singles games, some skips may not be competent to properly and concisely convey important information. Other skips may modify the truth to save your feelings or as part of their own strategy to correct your play. Such misinformation will only confuse your natural gift for making adjustments.

In lawn bowls, the jack may be placed anywhere from 21 meters to 29.5 meters in advance of the front edge of the mat. My eye level is 66 inches from the ground (I am six feet tall). Thus at 29.5 meters the angle between the horizontal and my line of sight is 3.25 degrees. When the jack is at 21 meters, the corresponding angle for me is 4.56 degrees. My bowls when lying flat have a height of about 4.25 inches and these bowls' diameter is 5 inches, so standing up each has a height of 5 inches.  A jack’s diameter is 2.5 inches. Doing the calculations I get the numbers in the table below.

It is worth noting that a bowl can be as much as two feet in front of the jack and still completely hide it, so even though the jack is covered a good draw can readily become the shot bowl.  Also, even if the jack is completely hidden as seen from the mat, there can be plenty of room to catch and trail the jack without touching the covering bowl.
