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.

스쿠버 다이빙 경력에 따른 무감압한계 잠수환경에서의 반복잠수가 Epinephrine, Norepinephrine 및 Dopamine 변화에 미치는 영향
소이용(So, Lee-Yong),한길수(Han, Gil-Soo),오문엽(Oh, Moon-Yeop),강명학(Kang, Myong-Hak) 한국체육과학회 2016 한국체육과학회지 Vol.25 No.1
The purpose of this study to verify the effects of repetitive dive in the No Decompression Limit(NDL) diving environment on the changes in Epinephrine, Norepinephrine and Dopamine depending on scuba diving experience. This study targeted 9 healthy adults of an unskilled group with less than 40 diving frequencies and 10 ones of a skilled group with over 40 diving frequencies. The study findings are as follows. After repetitive dive, Epinephrine decreased to 29.14% in skilled divers (p<.001) and increased to 48.34% in unskilled divers, so there was a statistically significant difference (p<.05). Norepinephrine decreased to 40.22% in skilled divers, so there was a statistically significant difference (p<.001). Norepinephrine decreased to 4.21% in unskilled divers, but there was no statistically significant difference. Dopamine decreased to 75.02% and 59.96% in skilled divers and unskilled divers respectively, so both groups showed statistically significant differences (p<.001). Norepinephrine and Dopamine declined in both skilled and unskilled groups after repetitive dive in the NDL diving environment, but Epinephrine decreased in the skilled group, while it increased in the unskilled group. This is because long stay or exercise in the cold environment led to an increase in heat production for maintaining a body temperature, the metabolic rate rose, shivering was caused by the decrease in body temperature and excessive stress lasted long during a dive.
