CHANGES IN SERUM CHOLINESTERASE AND TRANSAMINASE ACTIVITIES AFTER EXERCISE IN MAN / 体力科学

ABSTRACT

Changes in serum enzyme activities (GOT, GPT and ChE) were investigated in trained and control subjects both of which were made to perform exercises of three different intensities (mild, moderate and heavy) . It was thought that this study might aid in elucidating the relationship between serum enzyme activities and the blood lactic acid level as an index of hypoxia.<BR>The results are summarized as follows<BR>1) Both activity levels of the serum enzymes and the concentration of blood lactic acid were higher at rest in the control subjects than in the long distance runners.<BR>2) Activity levels of serum ChE as well as GOT, GPT increased in propotion to the intensity of work.<BR>3) In serum GOT, GPT and ChE activities no statistically significant difference was found between the two groups in all work loads.<BR>4) Relationships between the increase of blood lactic acid concentrations and those of the serum enzyme activities at three minutes after the exercise were all found statistically significant (P<0.001) (with GOT r=0.845, GPT r=0.768 and ChE r= 0.835) .
