Outline of Final Research Achievements

The purposes of this study were to develop a method for reconstructing the body surface dimensions of human body in motion, particularly during the performance of swimming, and to determine the influence of adopting different breathing techniques to the mechanism of maintaining the horizontal body alignment and to the swimming efficiency. We have succeeded in developing such a method and confirmed its validity in reconstructing overall shape of the entire body in various motions -- repeated simple motions performed on dryland as well as front-crawl swimming. However, we failed to reach a satisfactory result in accurately reconstructing the changing patterns of abdominal shape of swimmers in response to adapting different breathing techniques (abdominal breathing maneuver and chest breathing maneuver) during the performance of front-crawl swimming. We are determined to continue working on this problem to make the system fully operational so as to achieve the original goal.
