Outline of Final Research Achievements

The aims of present study were 1) to develop the experimental setup to examine central and peripheral circulation during water immersion (WI), 2) to explore the relationship between both circulation system, and 3) to examine whether water temperature affect this relationship. In experiment 1, we developed the experimental setup to examine central and peripheral circulation during WI. Using this setup, we found increased oxy-hemoglobin concentrations during WI, and these activities depends on brain area. The results of experiment 2 showed oxy-hemoglobin concentration during WI depends on water temperature and water level. Based on these results, we should consider the effect of peripheral circulation activity, autonomic activity and heating during WI on cerebral circulation activity to develop new criteria for aquatic exercise in safe.
