스쿠버다이빙 초보자의 부력조절기 사용에 따른 공기사용량과 실패횟수 분석

초록

This is an experimental research to verify a buoyancy compensator’s rolls for a beginner of scuba-diving. Subjects of this study is 66 adults who are participated in the summer camp for the Leisure Sports Events of 2010 Summer(Leports 2010). the 33 subjects are involved in the comp arative group, while the other 33 subjects are in the experimental group. The volume of air consuming was measured at the point of decent, underwater swimming, and ascent to the surface of water. Results of the study indicates as following:Firstly, the non-using buoyancy group uses more air at the point of decent to compare that of the using buoyancy group, that indicates more probabilities of diving related injuries such as sinus squeeze, carotid sinus reflex, breathing resistance, or barotrauma of ear can be developed. Secondly, the non-using buoyancy group uses less air during the underwater swimming from the point of decent to the point of ascent. However, there are many chance of unwished ascent with the non-using buoyancy group. Thirdly, the relationship with a partial correlation between the number of mistake and the submerging at the decent area was significant, that indicates more chances of accidents may happen at the beginning of diving for the novice diver. Discussions regarding that the instructor should teach and request using a buoyancy compensator to the beginner to prevent unexpected accidents are provided.
