An Evaluation for the Development and Motor Patterns of Backstroke Swimming in Children

The motor patters and development for school children in back stroke swimming measured by the method of observational evaluation on VTR movie analysis. The results were as follows; 1) The percentage of motor pattern 1 and 2 for Ba, Cr and Br stroke swim showed approximately 50% for appearance. This suggested that the three styles of swimming ability for school children could be integrated in these motor pattern levels. 2) The body position during swimming was considered as the remarkable critical motor pattern changes due to reduce the passive drag against streamlined position. 3) The timing of stroking and rolling of upper body for backstroke swimming were estimated highly difficulty in terms of motor pattern development. 4) With the progress for the development of motor pattern, the ability of three styles swimming could be improve these swim velocities when appropriate teaching opportunity should be done individually
