| Outline of Final Research Achievements |
This study examined possibility to use artificially carbonated water (CO2-water, CO2>1000ppm, 32-35 C) for maintenance and improvement of muscle performance. A dominant forearm was soaked in CO2-water during rest-time of ten minutes between series of intermittent hand-grip exercises. In comparison with the case of fresh water of a same temperature, progress of the muscle fatigue tended to be inhibited by CO2-water. During the immersion, muscle blood flow was significantly larger in CO2-water than in freshwater, similar to the skin blood flow. Recovery from the fatigue, however, did not show any difference between these two water kinds so far. The results suggest that soaking of a body part including dominant muscle of the exercise into CO2-water during rest-time of intermittent exercise (e.g. the throw movement during a baseball game) improves muscle blood flow and might inhibit a deterioration of the muscle performance in the exercise following the resting.
