Twenty-three male collegiate swimmers underwent a spinal alignment test and a passive drag test. The spinal alignment test measured the angles of thoracic kyphosis and lumbar lordosis when the participants took the prone streamlined position on land. The spinal alignment data were collected using a Spinal Mouse to record the sagittal outline of the back. The passive drag test at streamlined position was measured by the passive towing method using a towing series comprising four 20-m towing trials at towing speeds of 0.7 m/s, 1.2 m/s, 1.7 m/s, and 2.2 m/s. Significant correlations were found between the angle of thoracic kyphosis and the coefficients of drag at 1.2 m/s, 1.7 m/s, and 2.2 m/s. No significant correlations were found between the angle of lumbar lordosis and coefficient of drag at any towing speed. These results suggest that the angle of thoracic kyphosis during the streamlined position would have a significantly effect on passive drag generated by towing.","PeriodicalId":187035,"journal":{"name":"Japanese journal of sciences in swimming and water exercise","volume":"48 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115783902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In swimming competitions, the same criteria as for other sporting events cannot be used, because participants use the spectators' seats. In a swimming competition, crowded and/or close-contact situations are not formed, since each swimmer uses each lane in the race. However, swimmers in a competition may be crowded in the warm-up pool and locker room. Therefore, it is necessary to consider the control of the number of participants in the swimming competition in the order of the locker room and the warm-up pool. The results of this study show that the number of swimmers using the locker room at the same time is an important factor.","PeriodicalId":187035,"journal":{"name":"Japanese journal of sciences in swimming and water exercise","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132779173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
