Outline of Final Research Achievements

This research aimed at exploring the commonality and diversity of swimming motion for competitive swimming. As a result, the commonality recognized that swimming speed could approximate exponentially with age from junior to senior. The diversities were observed in the pull motion, the recovery motion and the both arms coordinated motions. The presence or absence of respiration motion, which is one of the stroke diversity within the individual, revealed that the stroke time increased by about 0.03 seconds due to the addition of respiratory motion, causing a decrease in swimming speed. Furthermore, it was suggested that the phenomenon that the underwater hand trajectory slips backward during respiration was a factor of deceleration.
