| Research Abstract |
Skin blood vessel is dilated at the water temperature of around 35 degrees Celsius when we take a bath in carbon dioxide-rich (more than 1000ppm) hot-spring, and skin blood-flow increases. Animal experiments revealed that prostaglandin E2 (PGE2) is involved in this vasodilatation. In contrast, PGE1, PGI2 nor nitric oxide may not contribute to the vasodilation. Expression of enzymes contributing to the final step of the biosynthesis of those PGs was not changed during CO2-water bathing for 30 min. The results suggest that bathing with CO2-water may affect not the amount but the activity of the enzyme in the skin. On the other hand, the blood vessels in skeletal muscle of underwater body part was dilated, which produced increase of blood flow. Muscle soreness and hardness after resistance exercise was recovered by bathing with CO2-water more quickly than that with normal water. The result suggest that the CO2-water bath may improve a myofunction.
