Abstract |
INTRODUCTION The purpose of this study is to analyze changes in blood lactate and hemoglobin level following scuba diving with 3 different types of decompression. METHOD The subjects of this study were 12 students from M university with scuba diving experience. All subject conducted scuba diving 3 times with each type of decompression in the random order. Decompression types include 5m safety decompression stop, deep stop, and circular (spiral) decompression. Blood samples were collected before and after scuba diving for biochemical analysis of blood lactate and hemoglobin level. RESULT Blood lactate levels were increased in all decompression types after scuba diving. 5m safety decompression stop increased 28%, circular (spiral) decompression increased 25%, and Deep Stop increased 17%. However, there was no difference in an increase in blood lactate level among decompression types. Blood hemoglobin levels were also increased in all decompression types after scuba diving. There was a significant difference in an increase in blood hemoglobin level among decompression types.
While Deep Stop increased 6%, 5m safety decompression stop and circular (spiral) decompression increased 3% each.
CONCLUSION The results of this study suggest that 5m safety decompression stop and circular (spiral) decompression may have the better protective effect on decompression sickness compared to Deep Stop. |
