Much of the equipment in these videos is solely used, designed and made by Leafe Elite Swim School. At this stage children have already learn`t basic skills, a straight leg flutter kick and good extended high body position in the water. Below you see 5 year old Tyler with a small floatation device in hand this does a number of things. (1) It ensures good muscle memory and consistency of stroke due to the fact the hand returns consistently to the same position.(2) The small board lacks boyancy and sinks if there is to much downward force, this enables the head to be in the correct position when breathing limiting lateral hip movement and aiding stroke timing. NoticeTyler has very little lateral hip movement and good extension of stroke, you might say she looks efficient through the water. Same can be said with her backstroke kicking good extension and body position in the water and a straight leg flutter kick.
