| pubmed-article:7182603 | pubmed:abstractText | We assumed the possibility of adopting FDP as an index of fatigue and carried out examinations upon various load conditions causing stress. For our observations other indices which are thought effective for fatigue evaluation, such as urine CA, flicker values, response time, Uchida's Kraepelin test, and examination of subjective symptoms recommended by the Japan Association of Industrial Health, were adopted at the same time. 1) Both mental and physical loads increased FDP values both in serum and in urine. 2) These changes in FDP values agreed comparatively well with the changes in CA by load. 3) The FDP value showed changes by load which was so light that it did not induce functional deterioration detectable by the response time or the flicker value which was considered to be one of effective physiological indices. 4) The extent or degree of subjective symptoms found by the survey agreed well with the changes in FDP values. Through above examinations, FDP values of serum and urine seem to be useful as an index of transient fatigue; especially they can well reflect mental fatigue which cannot be indicated well by other biochemical indices. Also FDP can well show individual characteristics, namely FDP indicates comparatively satisfactorily both individual sensitivity and specificity. Furthermore, this method does not require special techniques and examinations can be done simply. | lld:pubmed |
