 note = {text, The purpose of this study was to clarify the training process during crawl stroke flip turning motion by use of under-water force plate and NAC high speed video camera system. A beginning swimmer was employed as the subject to perform flip turn motion during about 30 days training. The results were obtained as follows, 1. There were significant differences in the 10 m total swimming turn time between pre (7.74s±0.25) and post (7.54s±0.23) training (p<0.05). 2. The depth for the trajectory of C.G decreased from 38.9cm to 23.5cm. 3. However ,The magnitude of impulses during push off phase increased from 532.0N to 827. 6N respectively. 4. It was suggested that stream-lined position should be taken at the twist- turning phase smoothly. 5. Moreover, the turning motion would be improved skillfully when the swimmer should be acquired the appropriate magnitude and the direction of power at the push off phase.},
