高校生のスポーツによる生体負担度

(高校生の生体負担度の研究 第一報)

抄録

The purpose of this report is to measure physical load of students on practice of sports in a senior high school.
Donaggio's reaction on urines before and after practice of base-ball and kendo by students demonstrates the following results.
1) A coefficient of correlation between the titer of Donaggio's reaction of deprote-inization treatment by heating urines and that of omitting the treatment by heating urines before practice of base-ball shows 0.84 and that after practice of base-ball shows 0.83, which are very correlative.
2) The titer of Donaggio's reaction corrected with specific gravity of 1.024 is better than actual titer of Donaggio's reaction.
3) The results on the high titer of Donaggio's reaction corrected with specific gravity of the urines of students before practice of sports indicate accumlation of fatigue, which needs to be taken steps for them to encounter more exhaustion and to get over tiredness.
4) Counterimmunoelectrophoresis shows the presence of HH, Znα₂ and myoglobin in the urines before practice of sports and the increase of Znα₂ and myoglobin after practice of sports. The presence of myoglobin in the urines before practice of fatigue of foregoing day.
5) There is little correlation between titer of Donaggio's reaction and complaints of fatigue caused by physical load on practice of sports.
