[Changes in the content of sulphydryl groups in rat tissues under the effect of muscular activity].
The muscular activity was established to affect the content of SH-groups in the tissues of skeletal muscles and myocardium. During 15-minute swimming the total content of sulphydryl groups lowers in them due to a decrease in the content of protein and nonprotein fractions. Swimming for 2-2.5 h has no effect on the content of SH-groups in the skeletal muscles and evokes its decrease in the myocardium. A more prolonged swimming (4.5-5 h) causes an increase in the amount of sulphydryl groups in the skeletal muscles due to its growth in the protein fraction. In the myocardium the total content of SH-groups and nonprotein fractions lowers. A long muscular load has no effect on the content of sulphydryl groups in the liver.
