TIME ANALYSIS OF SONKYO MOTION IN PROFESSIONAL SUMO-WRESTLERS
Keywords: etiquette, sumo, time analysis
AbstractThe purpose of this study was to investigate the spend time for sonkyo motion in professional sumo-wrestlers. The sumo tournament which held in September 2007 was videotaped. And using this film, the motion time was measured. Moreover 5 motion phases were defined in matches respectively. Results indicated that Yokoduna (the highest ranker) showed the longest motion time in these wrestlers. It is generous that slow speed motion indicates having room to breathe. This may suggest that Yokoduna has the dignity as the highest in rank. Therefore Yokoduna showed this result. However there is no evidence to clarify that thing. It is necessarily to correct more data of motion time in order to clarify the relationship between motion time and rank in further study.
