| Outline of Final Research Achievements |
We investigated whether the immersion of extremities including agonist muscles into artificially made CO2-water influences improvement of muscle conditioning in fatigue after exercise. Recovery of muscle hardness due to resistance training was promoted by CO2-water immersion. In addition, the forearm muscle blood flow after the intermittent handgrip exercise increased significantly in the CO2-water immersion compared with the tap-water immersion. The gene expression level of PGE synthase was higher in CO2-water suggested that PGE 2 might be involved in vasodilation when dipped in CO2-water. Furthermore, there was a tendency to promote recovery of muscle fatigue after very short maximum effort exercise and to promote lowering of blood lactic acid concentration. The results of a series of the study suggested that high concentration artificial CO2-water may promote recover from muscle fatigue induced by high intensity exercise and contribute to improving conditioning of the muscle.
