TURNING TECHNIQUE OF ELITE SWIMMERS IN BUTTERFLY AND BREASTSTROKE

Abstract

The objective of this study was to determine the kinematic differences of the turning technique in butterfly and breaststroke between elite Hong Kong swimmers and the finalists of British Commonwealth Games (BCG) in 1982 during 100m butterfly and breaststroke events. A video head was fixed into a water-resistance box which was put underwater and mounted on the side of the pool. The motion of the butterfly and breaststroke swimmers were filmed in the sagittal plane. Then the video materials were processed usirlg a PEAK Performance System. The kinematic parameters included distance out, time out, and average horizontal speed out. The results showed that the average horizontal speed out for most of the subjects were smaller than the average horizontal speed out in BCG (1 982).
