Although carbon dioxide had an increase action of a skin blood flow, a blood-pressure fall action, etc. to the human body, in order to utilize these actions for conditioning of Athlete, experiment using carbon dioxide-rich water produced artificially was performed. The upper limbs of both sides were immersed in artificial carbon dioxide-rich water and fresh water which were set up lower than the temperature of a human body and comparison examination of the recovery process of the skin temperature of since it is immediately after taking out from water was carried out by fresh water and artificial carbon dioxide-rich water. In five healthy adults who do not have trouble in the blood circulation of a finger, subjects are two men and three ladies. A temperature set up three temperature belts, 15 degrees, 20 degrees and 35 degrees, and immersion time was performed in 5 minutes, 10 minutes, and 20 minutes, and observed the recovery process of skin temperature in thermometer. Three fixed points were established in observation of skin temperature and three points, a middle finger tip, mid-palm, and distal portion of forearm, were made into the viewpoint. Result: The early recovery tendency of skin temperature after immersion was seen to carbon dioxide-rich water between fresh water and carbon dioxide-rich water. Further the skin temperature of the portion immersed in carbon dioxide-rich water from immediately after immersion showed the tendency higher than the skin temperature of portion immersed in fresh water and which becomes large as it went to the tip, and the temperature of the portion dipped in carbon dioxide-rich water from immediately after immersion was the largest at the middle finger, and showed the small tendency by distal portion of forearm Moreover, the difference may not be seen in recovery time of skin temperature, by evaluation with thermometer. When both upper limps were immersed to the water set as 35-degree, recovery of skin temperature happened for a short time and the difference of recovery of skin temperature showed the few tendency in the comparison between fresh water. Consideration: The increase effect in a skin blood flow which carbon dioxide has also in artificial carbon dioxide-rich water was observed, and it was thought that it was utilizable for maintenance of condition of Athlete or rehabilitation. However, there is also a case from which the increase effect of a skin blood-flow was not acquired, and it was thought that examination was required further.
