We spent a little time lately going back over body position. My group is made up of some older kids, so I take a chance to explain to them more of the science part of body position. Some will grasp it with the discussion, and then some will hopefully grasp when we get into the water.
Explaining about Center of Gravity in the water, and explaining that gravity still effects us in water. The added force to our body is buoyancy which is dictated by oxygen. They grasped the concept that the oxygen is mainly held in the lungs and a drawing on a white board to show how this would effect our body position in the water compared to on land with a human on a scale.
We discussed what it would mean to "lean on the lungs" to adjust the body position in the water. Also talked about how many swimmers resort to trying balance on their center of gravity rather than their center of buoyancy and we talked about what position that would result in while swimming in the water.
My challenge to them was to adjust their body positions to try to find their own center while swimming. Many made adjustments. Although not all of them have found that center, they seem to understand a little more about changing their body position and how to do it. Noticed much better undulation in butterfly and breaststroke as they know the desired position, and now they know how to adjust that body position they have tried to make adjustments to get to those desired positions.
Freestyle has been harder to make the adjustment, but I have noticed many of them attempting to make that change. Hopefully as they struggle with obtaining the desired body position, they learn this skill into their muscle memory or myelin (whichever one you believe in).
