Outline of Final Research Achievements

The performance of autonomic nerve indicator was improved in the following manners. [1] an algorithm for reconstructing the data timeline in which data were rearranged in reverse from each ventricular contraction event to respectively required elapsed time, because almost athletes have a psychologically preference for the indication synchronizing with their own ventricular contraction. [2] the introduction of a small prototype device made it possible that the attachment site of measuring device changed to the nasal bridge where less interference to competition practice for athletes. These devices was combined with the frequency analysis with the use of the maximum entropy method, resulting in a vital control support system aimed at aimed at the enhancement of shooting ability.
