| Outline of Final Research Achievements |
Competitive swimming start needs sufficient water depth in order to avoid the head crash accident to pool bottom for competitive swimmers. The purpose of this study was to investigate the relationship between the depth of swimmer's head in water and posture above water for prevention of crash accident in swimming start.
Thirteen male competitive swimmers participated in this study. Kinematic data of the swimmers during swimming start were obtained by motion analysis. The correlation between the deepest point of swimmer's head in water and the trunk angle (at take-off and at water entry) were investigated. There was no significant correlation in any variables. This result suggests that motion in water after water entry strongly affects the depth of swimmer's head. It is difficult to avoid the head crash accident by monitor only motion above water before water entry in competitive swimming start.
